I bought a fully loaded 04.5LLY 8 years ago,89,000miles, I’ve drove and worked in 27 different states with this truck without a hiccup. It’s been in cold-30 deg Colorado winters to 110deg New Mexico summers. I’ve driven over a dozen trips from Pa-Tx without shutting the truck off and napping in a parking lot while watching dvds in the back seat. This truck has been the most dependable vehicle I’ve ever owned! These trucks are mind blowing dependable. Don’t worry about the motor, trans, rear etc. the only thing your gonna be replacing is brake lines, fuel lines, and front end parts. Do NOT lift:level your truck with T-Keys!!! The truck will eat front end parts for breakfast!!! Spend the money on proper lift kit or leave it be! I made mistake and did T-keys running 33/11/18 and I personally was rebuilding the front end almost yearly, untill I upgraded everything to kryptonite/PPE parts. My PPE tuner, gets me +21-23 mpg highway and +-18 city. Just remember if you buy one, there almost 20years old, prepare for stupid issues I mentioned(brake lines, hoses, fuel lines) once you replace these parts your good to go. If your not a do it yourself, mechanically inclined person, (learn the truck), do the work yourself, or prepare for spending $$$. Meaning replacing brake lines cost $200 for every line. Having a mechanic or dealer replace them probably $1,500-2gs. Do the work yourself, save money or buy a Malibu! DURAMAX FOR LIFE HERE!!!!
Thanks for the comment and stopping by the channel!! I agree 100%! I plan to eventually redo my LLY front end as well with quality stuff like you did and not have to worry about it.
I totally agree , I just bought the DT750 trans from calibrated power 6spd conversion and wow my LLY rolls down the highway at 1,920rpms at 80+ mph pulling down 22+ Mpgs
So far, this video is one of the best breakdowns I’ve seen for Duramax. Are there any major differences between the 2500 setup and the 3500 that should be mentioned? What are these trucks rated to tow legally? I’m not interested in hearing from someone that towed their neighbors 747 across the cow pasture.
@@stayfreenotsafe Thanks for the compliment, a lot of thought went into this video! One major difference between the 2500 and 3500 is that all 3500s get the larger 11.5" rear end (gas/diesel) whereas only the diesel 2500s get the 11.5 rear end. Good question though. Thanks for watching!
I think it’s funny how relatable this is for me because I travel the country pipe welding in plants and I bought a malibu to travel with for the fuel mileage. I’ve been all over the country from the carolinas to cali and everywhere in between and the only thing I’ve replaced on the Malibu was the battery and 1 headlight bulb. Extremely reliable. I just bought one of the cleanest lly’s I’ve ever seen a month ago with cash and in the process of modifications and preventative maintenance. Taking the torsion keys off of it from previous owner and dropping it back down to stock. Now I’ll be able to take my Harley on the road with me instead of having it shipped. Really Looking forward to traveling with the lly, always wanted a duramax hopefully it’s good to me.
My 05 lly just hit 800000 miles today and is still strong never had a problem
Congrats!! That's by far the highest I've read in the comment sections haha! Keep on truckin' and thanks for watching!
Pictures or it didn't happen
Ur a random stranger on the interwebs talk shizz section...me nor anyone else has anything to prove to you. What do i care of some random person or the Gods of diesel trucks have a certain faith in milage on my dang truck dude. Please explain why we should all post a pic of something just so you and all the other little minner-net doubters are worth validating my life too. If the sarcasm wasn't enough I'd be obliged to tell you to somewhere and f@#k off. @jimjim6803
Show us a picture
I met a guy a couple of years ago he had 780,000 miles on his 2011 Chevy Duramax. . He was running hot shot towing.
LLY’s are probably one of the best Duramax’s you can get. If you replace that mouth piece and intake with a LBZ one and put a oversized aftermarket radiator, tuned and deleted they’re just great. Also if you upgrade the head gaskets and studs it will be pretty much bullet-proof
100% agree!! Thanks for watching!
My next project thank for the info john
You pretty much described everything done to mine and it runs like a beast
Easy to do yourself? Cost to get all this work done self installed?
@@OurFulltimeAdventure The head gasket job is not easy but once you do that. Should last the lifetime of the truck for the most part.
I AGREE, I have 2004.5 that I bought in 2006, it now has almost 500k miles, I’ve put S&B mouth piece and Banks Economind tuner, Banks cold air intake and Banks exhaust, I had to do head gaskets about 325k miles and a new OEM Garrett turbo at about 400k. About every 150k miles I’ve had to replace the fuel filter head/primer. That’s all I’ve done in 17 years. I just bought another 2004.5 with 143k miles on it, for my 16 year old son. So yes I defiantly agree.
That's awesome!! Long live the LLY! Thank you for watching!
i have a 2004 6.6 lly with 364k kilometers on it and it still drives like its brand new
LLY is way to underated
I agree!
let's keep it that way, don't need prices going higher than they already are...
I like your video bro. I’m actually glad I got an LLY as opposed to anything else. I’m super happy with it
Thank you for the compliment! Likewise - I'm very happy with my LLY! No regrets!
I have an ‘07 LBZ with 651,000 and counting.
No injector issues yet, no head gaskets, only mods I’ve done was egr delete and 4” straight back exhaust.
I think that's the most miles of any comment I've read on this channel! Thanks for watching and keep on truckin'!
All thats needed
My 07 LBZ is at 533,000 all original including injectors
Lbz lmm the best
I have a 05 LLY with 260k miles I’ve done a head gasket and EGR delete. Done a turbo swap along with down pipe to straight pipe. Full cold side HSP piping followed up with EFI tuning from calibrated power to play it on the safe side. I’ve driven this truck from west coast to the east and it’s been thru Ohio winters and Minnesota as well. Love my truck even when your offered more then what you paid for it. I bought it for $15k back in 2010 still have it till this day 🎉2023 coming soon
I can totally relate! Wow 15K sounds like a good deal!! Thanks for watching and the comment!
It’s crazy they still worth like 15k today 😂
@@m57.ruslan So true considering its age!
I bought mine in 2012 with 125k miles for 20k. Did not realize at the time that it was a great deal! Now I’m at 286k miles!
I own 2 2004.5 duramax LLYs the reason they run hot is yes the intake airhorn , but also the radiator and clutch fan is smaller diameter and the fan has 9blades and moves less air , but you can upgrade with LBZ rad and fan , great engine and I've had no serious issues
Good to know on the fan, I'll look into upgrading that someday! Thanks for watching!!
The upgrade parts is so worth it
I just picked up an 05. Added S&B MP. Mbrp down pipe mbrp 4" exhaust with muffler. Modded stock air box slightly. And a banks hot side 3" turbo pipe. No tune yet. Truck is a whole new beast! Love it
Nice setup!! Love the 05. Thanks for watching!
Do you think the hot side intercooler made a significant difference
@@2smoker_775 everything together is noticeable. Each on its own. Eh.
Lly has had AFE CAI, PPE tuner(tow setting level 3),4" cat back exhaust, 3 inch lift, 285/70r17 tires, and custom Transmission tune since new in 2005. Pulled 13k pound 5th wheel it's whole life over the Dakota's, mountains, and the south. Never seen the temp gauge over 190 and only a slight uptick on the trans. I was surprised to read about people having cooling issues on them. 180k miles had to do the head gasket though, that's a real thing. I Get 25mpg empty 18.5 mpg pulling that 13k pounds. Will be adding a lift pump to hopefully extend the fuel system. Father has a 2020 rocky ridge addition, super cool and beautiful truck. You barely know you're driving a diesel and that 10 speed seems flawless. That truck is also ginormous compared to the 2005 body style. My 08 half ton physically seems bigger but the older ones have a lot better visibility and they really did have better build quality then the decade after
Solid truck!! I was also surprised to first hear about cooling issues on LLYs. Thanks for watching and keep on trucking!
I've had an LLY for 4 years. Had the injectors gone over and the head gaskets (along with a tune from the shop I did work) done along with odds and ends everywhere including the y bridge. Literally after 3 years of running on the 1 tune, I just figured out that I need to turn on efi live on my edge and now I got the sauce I've always thought I was missing. Still barely smokes at all, but will absolutely blow the doors off a powerstroke
How hard is a upkeep on one of these diesel duramax? I’ve been looking for a new hauled truck and the cat eye Silverado always catch my attention.
@@CSERepair all diesels are gonna be a gamble if they aren't new, but either way still expensive. Just gotta know what you're doing, make sure your injectors and pump are lubricated. And unless you got deep pockets, keep your foot on a diet.
Thanks for watching!
My 2005 LLY has 208 and I love it
Keep on trucking! Thanks for watching!
Very informative! I love my LLY!
I appreciate you watching & commenting!
Just getting my 2005 GMC Sierra 2500HD off non op. It was overheating after a deer hit that also damaged grill and bumper (both of which I have replacements for). It is at the mechanic's and he thinks a new radiator is needed. SHould I get a larger aftermarket one? Should I also have him replace intake elbow while he's at it? New tranny/engine oil cooler while he has it? Or should I get these done later? It's all stock with factory tow package and I am original owner--has 220K mi. Will be putting a 1900 lb. truck camper on it. Previously used to haul hay and 23' gooseneck horse trailer. No problems until deer hit. I'm putting 265/75/16 tires on it. It needs to pass CA smog, so no deletes. Objective: safety and reliability.
That's a good question, and I'm no mechanic myself so i don't really feel qualified to answer that. I know it's a late response, but I would look into getting the LBZ radiator and just for future reliability and resale value. I never had overheating problems with my stock LLY radiator though. Thank you for watching!
I have LLY 2005 I've had it 5 years never had a problem I love my truck
Right on! Thank you for watching!
LLY is the goat most definitely,
I'm running a mishimoto high performance radiator, intercooler and transmission cooler, full HSP Max Airflow deluxe kit, Flopro 5inch straight pipe, no muffler or resonator, 3 inch Flopro turbo direct pipe..
Currently looking at the RDS 64mm 9 blade turbo as well 💯
Right on! That's a solid truck right there. Finally someone else who agrees with me! Thanks for watching!
I love my LLY, it’s a work horse. You should consider custom tuning! You’ll love yours even more. So much more power, I don’t ever put mine on stage 1 because it feels gutless after keeping it on stage 4 daily driver tune (70hp) when not hooked to trailer. It’s hooked up to fully loaded dump trailer 90% of the time, I maintain it religiously, and it’s quicker than my supercharged Sierra! Just with tune, intake, mouthpiece, and exhaust.
It has definitely crossed my mind, just have no idea where to start! That's good to know though!
Also thanks for the sub!!

MOTOR OPS EFI LIVE CANADA 🇨🇦
Love my LLY Sierra! Lol, 0-60 in 4.79s and has hauled every trailer with tractor or truck I've hooked to it so far. 336k miles and still strong! 🥰
That's awesome!! Keep on truckin'!
Just a tune?
What mods to do 0-60 in under 5 seconds like that?
So I have a 2006, LLY five speed, Kodiak Monroe package, RV hauler. Is there a downpipe from S&B for that unit?
I have 128,000 miles on this unit and have just replaced the fuel primer pump in the is a Filter between the two rear tanks everything I read says it’s a good idea to put a premium Pass fuel filter and separator on my truck to help preserve the P3 pump and help longevity of the injectors. Is this a good idea
I'd definitely recommend installing a lift pump for better fuel delivery, reliability, and filtration. That's a good question about the down pipe, I'm not as familiar with the 2006 LLY so I don't feel qualified to answer. I have heard that the 06 LLY is just a de-tuned LBZ so I would think a 3" S&B LBZ down pipe would still work. Thanks for watching!
I use the AFE turbo mouthpiece, Diamond Eye down pipe along with keeping the cooling stack clean and there is no over heating. Don't abuse the truck when towing and the LLY will be just fine.
Nice setup! Totally agree. Thanks for watching!
i have ran my hard and it runs like a horse on crack. but yes before too long tranny will slip but that's the point to get a built tranny😀
Got a question I have a 2005 lly duramax that has 262k on it and got it at 252k couple of things I've noticed with it runs fine but one problem that just came up was when I was trying to pass someone it went to shift down and slipped out of gear had to pull over shut it off and ran well after that. one other question is that it's starting to start slower and slower not bad but noticeable I know I live in MN so its cold but it will be plugged in and on a trickle charge as well and over the winter been starting slower even in warmer weather im thinking its starting to be time for new injectors. if that is the case what injectors should I get and when I go to do them should I replace things such as head gaskets I wouldn't know what brand to go with or what to go with and then I would also do ARP head studs just looking for anything else you guys would replace well its apart. I tow a 40ft toy hauler for work around the country as im a pipeliner so it gets worked good speedily going through the mountains.
Thanks for the comment! I've never experienced the trans slip in my LLY so I don't even want to try to guess. As far as the slow starting, my truck has certainly done that and it turned out to just be bad batteries, sucked since it was like $450 for both and the old ones weren't that old I thought. Sounds like you may have already tried that kind of thing though with the help of a trickle charger, those tend to help batteries last much longer. Thats a good question on other suggestions for replacements while you're in there but I honestly don't feel that qualified to give advice haha. I haven't done much/any internal mods yet unfortunately. Thanks for watching and keep on on trucking!
It went into limp mode. Usually happens on the 5-4 downshift. If it happens once or twice you may be okay but it will get easier and easier to have happen. Injector choice depends a lot on what you want to do with the truck. You want a little or a lot of power. If you do bigger injectors and a tune or a big efi live tune. You will need a trans or additional supporting mods. Lift pump is a good idea also. LLY Duramax doesn't have one from the factory. As for head gaskets. Thats up to you. If you want the extra cost or downtime
'05 GMC 378,000 miles on it with no mods and completely stock....still strong!!! I'm getting ready for some tuning soon
Love reading this!! Keep on trucking! Thanks for watching!
I have a 2006 LLY, and the factory Allison 6 speed transmission. I bought it secondhand in 2018 with 84,000 miles, I currently have 160,000 miles with no major issues. The previous owner had installed a Banks cat-back exhaust, I decided to match it by replacing the factory air intake with the Banks as well. I sometimes refer to it as "old faithful", it's never let me down.
Right on!! Thanks for watching!
I have over 380,000. Did head gaskets my self.
Nice! Not to many of them out there. I have a fully built 2006 LLY myself
@@countcuda70 they're definitely hard to find (especially in an affordable price range). I have a short bed crew cab, which is what I wanted. The only thing I'm missing is the 4wd (I've gotten stuck a few times), but there weren't any available when I bought mine.
@@jerryreding7369 Took me a while to find mine also. I have a crew cab, short bed, 4x4 though. Had to drive 7 hours for it. Was a decent price but then came all the additions. It's fully built, front to back. Axles, engine, trans $$$
Fire Punk Diesel just put up a video of an LLY with stock internals. It put up 1400+hp with nitrous. 900+ fuel only. Even had stock head bolts
They aint going for reliability tests though
@@javadose317 It's been going strong for a while now. They tried to blow it up when they did 1400. It held and kept going.
I just purchased a 2006 GMC Sierra SLT Duramax 6.6 crew cab motor runs amazing motor and service was well looked after it has 639599km on it unfortunately has some rust but I’m fixing it up.
Right on! That's a lot of Km. but they are solid trucks!! Thanks for stopping by the 605LIFE channel!
Agree with your points. In 2005 I bought a new GMC with LLY Duramax been and excellent work truck, retired in to a yard plow truck few years ago but going to put it back on the road and park my 2014 Ram, still no codes on my GMC when you put a scanner on it, the dash on the Ram looks like a Christmas display, cant keep the warning lights off, seems there is always something setting them off
That's awesome you bought one new!! Thanks for the comment and thank you for watching!
I’m loving my LLY which I’ve owned since new.
I’ve I replaced the air inlet elbow, I replaced the turbo outlet down pipe, I replace the exhaust pipe went from 4 inch to 5 inch with a 6 inch top tip. I removed the cat. I removed any obstructions from the front of the grill. I replaced the transmission oil from Dextron 6 to Amsoil torque Drive and installed a PPE Deep and finned transmission oil pan. Finally I unplugged the EGR valve.
Now when I tow my 32 foot fifth wheel with a boat behind it my fan clutch doesn’t even kick in and my transmission barely gets warm amazing!
One more thing. The water pump is gear driven. So If the fan belt breaks you still have cooling fluid pump operation ( marine grade)
Forgot about the cold air intake I installed a while back.
Also went from 16” wheels to 18 inch wheels
Love to hear this!! There aren't many 1 owner LLYs left out there! Those all sound like great modifications and I can't wait to do the rest of that to my LLY! Does unplugging EGR valve cause a C.E.L.? Good to know about the water pump, that is sure nice! Thank you for watching!!

Can you tell me what part is and the name of the part that you put on the back of the turbo inlet mount piece so it won’t overheat where did you get the part and where do I find your video on installing it on a Duramax 6.6 turbo LLY. 👍
Here is my Amazon link to one that is only $60-70:
amzn.to/3YWEJsF
I bought the S&B brand turbo inlet but it was like $200 no joke. This one on Amazon has good reviews and seems to get the job done for way less the cost! You could also swap one from an LBZ - I have heard that it will directly replace the LLY one.
Thank you for watching!
You can buy a factory LBZ INTAKE AIR HORN and it fits the LLY you just have to trim your intake hose to fit it on super easy
I have the 06 LLY and honestly I think it’s probably the most reliable duramax. With it being a detuned lbz you can tune it up a little bit and be at a decent horse power level and get the benefits of custom tuning at around the original hp of an lbz so your not loading it up with power your getting good times and getting good power while keeping it very reliable and still being nice to that 6 speed trans. Mind you I’m at 330k stock trans and everything still drives smooth knock on wood. Good trucks.
I totally agree! Thanks for watching and the comment!
you have a lbz
I actually just had a DT 750 trans from Calibrated Power put in my truck with the 6spd conversion and tuning , I absolutely love the trans and lower rpm highway cruising and top end power it has , 80mph 1,920rpms
@@codyyellott117 There are 2006 LLY's. Now I will say this is only due to engine coding issues that occurred from EPA issues GM had coming out with the LBZ. That is at least to my understanding, I could very well be wrong about the reason. The 2006 LLY's are "Essentially" LBZ's that are detuned from the factory. There's not very many 06 LLY coded Duramax's, so it's actually pretty neat to see someone who has one. But to your defense as well, they are mechanically and short of tuning and code, an LBZ.
Nah my dude, if you look up the VINs there were indeed some 06's with LLY, I have one and I have crossed and matched all numbers on the vehicle@@codyyellott117
someone mentioned airbox mod, the factory box is just fine... there is tape from factory on fender well, take that off and run some foam insulation strip around airbox and you have one of the best TRUE CAI you can get...
That's really good to know, I ironically just changed the air filter yesterday, but I still have the stock air box. Thanks

ok i have a question that hopefully will get some answers. Im from europe and want to buy a pickup. Been thinking either 2005 GMC Sierra with LLY or 2000-2003 Ford 7.3 Powerstroke. Parts are not so big problems here in Norway. It would be my first pick up ever as a owner but i drove few and love them. I wont be hauling really big weights but for some reasons US pickups are cheaper then european 'versions' made strictly for up to 3.5T of total mass. Are those trucks good choice or is there anything else i should consider? I am interested only in diesel.
In my opinion those would be great trucks, especially an LLY - but I'm obviously biased! Thank you for watching!

If you want a solid reliable diesel that starts in the cold and has great power and fuel economy, go with the 2004.5 -2005 LLY DURAMAX over the ford 7.3 , I personally own 2 2004.5 chevy silverado 2500hd with the LLY DURAMAX, THEY ALSO CAN BE TUNED TO 530RWHP on a stock fuel system and small upgrades , get the DURAMAX you won't be disappointed 😉
@@rexgratteaux8655 thank u for good input 😎
i bought my LLY in 2007 I now have 235k trouble free miles. ive only replaced batteries and water pump... and #2, #7 icepick harness mod after limp mode, for $60 get the LBZ mouthpiece, keep fins clean on radiator i tow my boat in mid summer and never gets over 200f... cheap and fun to mod, i wont post all ive done to motor😀
They are SOLID trucks!! I've heard about the ice pick mod - hoping I don't have to do mine anytime soon but at least I sorta know what to do when it does happen. Keep on truckin' and thanks for watching!
Could you us an earlier or later radiator from day lb7 or lbz? To up the cooling?
I was wondering the same thing, I think you can swap and LBZ radiator to an LLY but not sure how involved it is. Thanks for watching!
No. In 06 with the lbz the radiator support got taller but not out the top but out the bottom
My buddy spent 30k on a 07 lbz with 120k on the clock. Then, he had to spend another 10k to get it road worthy. It's from the rust belt, so the undercarriage is rusted to shit. I bought a 05 LLY for 13k with 72k on the clock. It came from AZ not a spec of rust. I'd rather save 25 grand and put a little into an LLY any day of the week.
Same here!! Price is a huge factor why I believe the LLY is king and underrated. Thanks for watching!
If I can provide any information I own a LLY 2005, about 300,000 miles, have pulled heavy loads at the limit of the truck. installed a custom goose neck hitch.
know issues, fuel filter- water separator overheat in summer 100+ temp. causes leakage and vaporization of fuel in the line. fuel water separator sealing problems due to relief plug-bolt. I have used both brass and plastic. Brass works better in cold weather and plastic in warm weather.
I have replaced the master cylinder, Batteries, seals on the HVAC system, the shocks, the break pads and drums, alternator, serpentine belt, I have replaced the 2 and 7 fuel injector plugs using the repair kit, I have replace the head lamps and their housing, the mirrors (have the original doormans but they are damaged), the tail gate retention pins (with paper clips) and handle, I personally have performed every oil and fuel filter change, and replaced the control unit for the seat.
things I want to replace or upgrade:
I want LED head and tail light.
I need to replace an AC senor that is malfunctioning in the dash board.
the coolant system is leaking somewhere and I cannot identify where.
head liner is falling down.
want a solution for the pressure loss on the fuel-water separator in both extreme cold and hot weather. I'm tired of traveling with water just to cool off my engine when it over heats.
will probably have to replace the compressor for the HVAC soon.
I made a custom retaining pin for the head lamps, lost the original.
I lost the guide tube for the spare tire, I really wanted something I could use a power drill for.
need to repair fog lights (fogged over), and the switch (broken/ stuck from wear).
replace windows with tinted windows to block the sun from heating the cab.
get the upgrade package for towing.
based on my experience the LLY durmax with allison is the best model of the low end of power for the Heavy duty diesels for both day travel and towing.
desired future improvements that may make the truck more effective:
Hybrid modification (hybrid electric)
Heavier steel bumpers
electronic upgrade kit (to improve electrical management and hardware, so I can charge my work tools and computer with the freed up power or add accesories).
under rear fender tool box, so I can free up space in the cab and still carry my tools.
back up and driving camera upgrade kit
collision avoidance upgrade kit
fuel cover locked cover
option to add DEF and DPF (I don't much care if I do or don't, but it may become compliant in the future and I want the option)
most of my grips are with the frame the truck is built on and not the actual engine.
Thank you for the comment and for watching! Great to have someone with lots of LLY experience on here!! I can relate to a lot of those things you've fixed!
Once I was driving a 2004 Chevy 4500 Duramax it had about 104,000 miles on it and pulling a load up a hill it blew a radiator. It had never run hot. I believe it just had a weak radiator. I like the truck and the Duramax LLY that was in it. It had good toque
Sounds like a fluke accident. Glad to hear it was otherwise a solid truck! Thanks for watching!
With emissions it is not that you might have issues, IT'S WHEN. And it will be repeatedly.
Owned a 2005 since January 2007(27k miles).
253k miles.
Egr delete. Ppe tuner level 2.
Replaced front end 1.5 times. Surface level rust on frame. Spent $2500 fixing rocker panels last October. Alternator replaced. Bearing pulley in serpentine belt system replaced.
80-120k miles towing camper across whole USA.
Couldn't be happier with this truck. Funny thing is I didn't want a Duramax. I was gonna get a Cummins or power stroke.
Thats awesome to hear! That's a long time to own a truck nowadays! I am starting to think about replacing front end parts on my truck, but wow it's expensive for quality parts. Keep on truckin' and thanks for watching!!
@@605LIFE TTX has great bang for buck quality on uppers, end links, and outter tierods
Do you no longer have the video for the turbo inlet mouthpiece?
Good question, it's been awhile, I actually may not have done a video on that unfortunately.
By brother and I are currently working on his LLY duramax truck. It has a problem we are unable to figure out. It will run fine until the truck gets up to temperature then it will knock and run badly. The number one cylinder has had the injector replaced with no change in performance. All the fuel lines have been replaced as the lines have been pinched down over time. The FICM has been sent out for repair twice. We've checked the voltage to each of the injectors and they will get voltage when the engine is cold but not when it warms up. After all this work still the problem exists. It happens only on the passenger side of the engine. We are now looking at the ECM. Any other ideas to consider?
That's a tough one. At first I was thinking you might need to do the "ice pick" fix to the injector wiring plug/harness, but that still wouldn't explain why it only happens when it's up to temp. Wish I were more helpful. Thank you for watching!
Do you have a way to see rail pressure? Compare desired vs actual
@@countcuda70 A good scanner would be able to tell you. You might even be able to borrow a scanner at a parts store like Oreillys if they offer the right model.
@@605LIFE That wasn't for me. I was asking a question from the original post here. They said they had an issue. I was trying to get more information from them.

I'm new to the diesel industry. I bought an '04 Topkick C4500 with a second gen LLY. A little underpowered considering the curb weight is 11,500 on this truck. But nothing a tune won't fix
Nice, I dig those TopKicks! Thanks for watching!
The factory turbo on an LLY is 62mm not 64. 2006 Vin code 2 LLY is mechanically an LBZ. The engine came out before the LBZ tune was approved. GM used to offer the retune at the dealer. In 2006 was also the start of the 6 speed. Yes, Allison 1000 from 2001-2005 has a 6th gear that was turned off from the factory. 2003 - 2007 had the same interior/exterior with exception to the hood. 2003 and 2004 have a different hood then 05 - 07. LBZ had piston issues usually in higher HP. LLY/LB7 would bend rods. LB7 and LLY have the same block and rotating assembly. Heads, injectors and turbo are different. Also, most places that used to sell metal impeller water pumps have switched to plastic. They seem to fail less
Great info!! Thanks for the comment!!
Can the 6th gear be turned on

Lbz has 6speed(very big deal) & Lbz also has 50 more horsepower strictly through tuning-oh & my tuned 2004.5 LLY has 643k miles on it & I’ve never been into the engine (other than headstuds & head gaskets) & never been into the Allison 5speed either-it’s driven pretty hard daily 🤷♂️ best truck & the most fun I’ve ever had 👍🏼
Wow 643K might be the most I've seen out of all these comments! Thanks for watching!
I have 4 generations of duramax currently. 03 lb7, 2004.5 lly, 2007 lbz, 2008 Lmm . I love them all….but I’d take the LBZ over any of them. 6 speed Allison, it’s just refined better than the lly. And the cp3 injection pump puts our 26k psi.
That's quite the collection! Really can't go wrong!! Thanks for watching!
The only part on my lly that worries me is the ficm. But with only 146,000 miles it runs perfect and if I drive like an old lady I can get 22 mpg with it on the hiway with a crew cab long bed truck with heated leather seats.
Thanks for watching! Forgot to mention the MPGs in the video, but I agree, 20+ is certainly realistic. Sounds like a nice truck - sometimes wish I had the crew cab!!
If the ficm goes out, have it rebuilt. Pretty simple. Why worry about it!!!

Hey! svtDP Not saying you’re wrong I’m just curious. But I bought a 2005 LLY and I’m wondering does it come with a 64mm turbo or is it a 62?
I’ve been seeing both so I’m just not sure which one it actually is lol. Thanks 👍
It's a 62mm inducer. If you want to get technical. It's an 11 blade 62.6mm inducer. It's the largest turbo put on a Duramax

I have a 05 running 35s and it was always a bit of a struggle to steer at idle. I ordered a new steering pump from PSC. 300 bucks and a Sunday afternoon, I can steer with my pinky now. Best pump on the market.
How do you change the fuel pressure regulator
That's a good question and actually something I may need to do someday on my LLY - it's sometimes a little rough at idle. Thanks for watching!
Take your serpentine belt off , first unborn A/C compressor move to the side , drain 2 gallons of coolant from radiator , unbolt thermostat housing and driverside radiator hose , the fuel regulator is on the top of the CP3 INJECTOR PUMP is in the center of the valley , you will need a T25 OR T20 TORX BIT , there are 3 , 2 top , 1 bottom unplug sensor , use small 1/4 in ratchet , keep a magnet 🧲nearby in case you lose the bolts in the valley , reverse in order to buckle it up
Bought my 04 1/2 GMC dually new. I have removed the converter and installed a summit down pipe back exhaust system. Changed the restricted left exhaust manifold. Put on larger up pipes and a unrestricted down pipe then deleted the EGR system. Installed an AFE turbo inlet with larger turbo hot and cold pipes. Also have a cold air intake, I am sure I have forgot other things. This improved my fuel mileage towing 28,000 lb to 11.5 to 13 mpg depending on my right foot. Empty it gets 20 to 22.7 and has way more power than when I used a tuner adding 100 hp and torque 15 years ago. Now the truck has 200,950 miles and does not use any oil. I am in southwest Colorado

About to get my first diesel but can’t decide between a duramax or cummins I’m still in high school so obviously can’t afford to much but I just worry about a duramax costing more to work on I’ve heard cummins are cheaper and easier to work on but kinda want a duramax
Cheaper, not really. Easier to work on, depends. For the most part yes but plug and play is pretty on the Duramax and Cummins. Obviously not the 12v. You have to work to get power out of them. Some of it can be free though. A lot depends on the year trucks you're looking at. Sure a 12v or 24v are cheaper with initial cost but are hard to find clean. Those will command a price. Most are rust buckets. Unless you're going after a manual truck. The automatic behind the Cummins stock is terrible. Allison is a better transmission. They're about the same to build depending on the horsepower level you want to go. I have a built 12v and LBZ. I like the smooth nature of the LBZ/Allison over the rawness of the Cummins/NV4500. Plus the Duramax is a lot quieter. Makes long drives more pleasant. Not to say the new CR Cummins aren't nice too. Still have the sloppy trans. 47rh/e or the 48re are not really built for the Cummins. The 68re in the new trucks are terrible also. I prefer the interior of the GM more then Dodge/Ram. It's more comfortable to me. With the Ram. You're buying an engine. The rest of the truck I don't care for. All of this is subjective. I gave you what I prefer. Ultimately you will need to go drive them both and decide what's most important for you.
@@countcuda70 thank you so much yeah if I got a cummins it would probably be a 6 speed 24v I drive one and a 5 speed 12 valve at work but have always wanted a duramax so I’m trying to find someone with one that would let me drive theirs
Great insight!
Thanks for watching! Haha I'm biased but I say Duramax for sure, and chances are you'll find an LLY priced right out there somewhere, even in this market!
Everything about a dodge is better than a GM. It’s built like a truck, not a big car. Having worked in autobody, it’s obvious that the GM trucks are just awful. A mild fender bender in a Dodge or ford, you’re replacing the bumper. On a GM you’re replacing the bumper, weak bumper brackets, radiator, hood and fenders will bend right above the wheel arch. Absolute junk. The inner door panels are a joke, they’ve got an interior panel that the window motor mounts to and you have to reach in to get things disconnected, cutting your arms as you go. The engines themselves are about the same, yes the Cummins is easier to work on, no denying that. The auto in the Dodges isn’t that bad stock, and great built.

I just bought an LBZ last month, 4/29/2022. After doing lots of research i chose LBZ over LB7 and LLY for two main reasons. 1) Least amount of issues and 2) 6 speed Allison ready to go. I still considered LLYs, but only if they where low miles for a good price. I didnt come across one before i found the LBZ i ended up buying. Its almost been two weeks now and i am happy with the purchase so far.

Any Duramax is a solid truck! Nice find on the LBZ and totally understand your reasoning! Thanks for the comment!
LBZ has weak pistons.
@@GMCJay_lly They're not really weak. Most don't have an issue until 650+ HP. LLY and LB7 have weaker rods
LB7 and LLY rods can hold 650rwhp but that's pushing it
Head gasket vs piston (cast in Korea then switched foundry) is the best argument for the LLY.
It's not just headgaskets vs pistons. The pistons are not usually and issue until higher horsepower. Headgaskets are an issue on stock and modified LLY. The rods on a LBZ are stronger then an LLY. The block is also stronger on an LBZ

I heard the LBZ has weaker pistons and connecting rods and will melt down easier than the LLY. Is this correct?
If you drag race or sled pull or just hook up to another truck and try to yank each other you probably need to go through your engines anyway and replace all the weak things like the Pistons and injectors /turbo etc ..but if you going to go stock and just use it like a work truck they work just fine bro
LBZ has stronger rods then the LB7/LLY. LB7/LLY pistons are stronger. Pistons usually aren't an issue on the LBZ until higher HP levels. I wouldn't say melt down any easier. The LBZ block is built stronger then the LB7/LLY
So true!

An 06 LLY is an LBZ. No differences at all. The LBZ engine was released before the tune was approved. An 06 LLY is an LBZ engine with LLY tuning. Not sure if GM dealers still do it or not. Years ago you could have the LBZ tune put on an 06 LLY.
Any older Duramax’s are 10x better then any brand new overpriced diesel engine these run forever if maintenance good and don’t have so many issues very built engine, transmission, and the bodies and more likely outlive any brand new trucks.

I had a 2005 lly and there's absolutely no way it will gap a new L5P with a 10-speed.
After driving a new 10 speed you'd never want to tow with a five speed. For the time the LLy was good but it's completely outdated.
Haha that's my bad, I meant that the LLY would get the jump off the line from an L5P, simply because of throttle response, but quickly loose to the finish line. Those 10 speeds are sure nice for towing but I still wonder about longevity since Allison didn't truly make it. GM has a bad reputation for automatic transmissions. I have driven a lot of L5P 10 speeds and they are sure nice if I could afford one!
Also, thanks for watching!
@605LIFE I do remember the lly having very quick throttle response but I prefer more linear throttle response on the new trucks
Also one of my trucks with the 10 speed has 150,000 mi on it and absolutely nothing wrong with the transmission.
@@hyrumh8305 Glad I'm not the only one who thinks that about the LLY throttle response but I totally don't blame ya for liking those L5Ps!! Most L5P guys are too cool for my channel - so thanks for stopping by. Keep on trucking!
Actually the LMM is the last pre deff dmax
I wasn't 100% sure, good to know! Thanks for watching!
Izozo designed the first LLY for GM , than after that GM started to make the motor not to last GM bought izozo
On the money
Thanks for watching!
LB7 is king 😉
LB7s are great!! Thanks for watching!
LLY loosing fuel prime, usually after filter changes. Then they hit you with new fuel lines, my answer was tighten the fuel line clamps. Bought mine new in 05. Had to do the tranny twice, the first switched to Amz--o-l trans fluid, it was too slick, number three clutch failed. A 5 micron water air separator installed when bought. Always used fuel lubricants, head gasket failed, other than that it is a great truck. I won't buy the new ones that run on weasel piss and diesel. Mine has a large exhaust, chipped and can give and has given fast cars a run for their money. So in a year or so I will rebuild the truck and drive it for another 20 years.
That's awesome you bought it new, that truck definitely sounds like a keeper!! Thanks for watching!
No shot it can run on French fry oil 😂😂
They can run bio diesel
Maybe not stock but there are retrofit kits you can install to run 100% veg oil no joke! Not on anything past LBZ though as far as I know.
Definitely can’t go wrong with a LLY but I’m still going to believe the LBZ is the best one lol
