Balls deep with the 10 mm
I just did my intake gaskets and injectors on my 2004 yukon 6.0 and while I had the intake off and I was cleaning I had oil pouring out of the throttle body, probably a 1/4 quart.... This is common for these trucks to suck oil into the intake causing all kinds of problems from plugs fouling to rough idle to gunk building up etc. There is an updated driver side valve cover that can be installed that will help this as well as a catch can to alleviate the problems with oil infiltration of the intake. Hope this helps somebody else, and thanks for the videos as always matt.

I love watching your Tahoe videos. I have one myself and it runs great. I love working on my own truck and your videos make things for me to work on a lot similar. THANKS MAN!!!!
I wish I would've seen this video months ago. My Tahoe was giving me the same problem and couldn't figure it out. Very helpful video!!
It's funny how extensions and 10mm's can bring out the best in us! 🤣
I got 99 sockets but a 10mm ain't one.
That's a crazy job to do when you need to be at work in 1.5 hours......
Started watching your Channel about 3 months ago oh, I have a 03 Denali and I'm doing almost all of the same things you have done. The intake manifold gasket on mine was original Factory period after replacing it my Yukon runs like brand new.
Love the videos and I try to watch everything you put out. I recently purchased a 2004 suburban and have been through much of the same as you. My next step is to add remote start with a viper kit. I would be interested in seeing you do an install too.
Love this! This is me yelling if I drop something to love that u kept it original and plus the help you have showed me!
This one was funny. Glad you got that fixed. You make fixing things look so easy. thanks
Amazon sells a full kit for this for about $ 70 dollars. Includes valve cover gaskets, injector o rings, valley pan cover gasket and the intake manifold gasket.
I normally never comment suggestions on videos to make as this is not my channel, obviously, but I'm sure that we could all benefit from seeing you service your tire monitors!! Great video :)))
I love this car, I drive the Tahoe 2002 in Germany :D - I love how clean is your engineroom - love it - Best Regreats from Germany
You the Man! keep it real.. This is how I work on my car, Spend more time looking for tools .
Glad this was recommended. Got a similar issue with bank 1 lean. Time to do knock sensors and harness while I'm at it 🙄
Nice job I can’t wait for more video of the Tahoe 👍
Love your videos bruh, keep up the great work. When you got your extension stuck got me dead. The same thing happened to me and I left it but I got in a wreck and I saw my extension on the ground I was so happy to see it again lol 😂
Best video I’ve seen of yours so far! My wife was like what are you watching that is making you laugh so hard!?
The coolant hose going thru under the throttle body is to keep the throttle blade from freezing in the winter but I live in PA and have bypassed most of the cars & trucks I've had with no problem.
Whatever camera you are using, it captures nice clear angles on how to do this job, thanx man...
@ 6:18 all that "I have done plenty of them" really pays off🤣
I had this issue a while back with a 236k mile Sierra except it was throwing a knock sensor code too. So it’s a good idea to throw new ones in as well as an oil pressure sensor. I hear those are pretty common issues. That’s probably why someone had been under that manifold before you. I know you mentioned the knock sensors, but I was just throwing that out there for the viewers sake. Great video by the way.
Just ordered a sweat shirt. Keep up the great work.
Can't wait to do this on a van! That's where a mechanic comes into play.
Bro great content! Nice quality too I might add. I have a 2011 Tahoe but all these engines are the same you helped me thanks!
Shouldn’t be too much... OHH THAT IS ALOT
I subbed for the comedic value but stayed for additional comedic value.
Great vid, nicely edited too. Thanks very much. LOLOL, that extension fiasco was priceless.... something similar happens to me every time
Looking back at this job I can't believe this was the first thing I ever did mechanically to an engine with no experience. Probably saved myself a bunch of money though.
I say this every time I see this truck, BUT DAMN IS IT CLEAN!
Got to love the 70's pornography music........not that I know what it sounds like😏!
Your engine bay is CLEAN!! Looks good.😃👍🏁🇺🇸
@ 0:02 You get a great demonstration of how the G80 works. This truck has over 200K and it is still holding up and doing its job.
Great time to change the oil pressure sensor on the LS1 when the intake manifold is off. The knock sensor covers looked good and tight but you might be back in there some day for those, too.
Great video! Had a question I’m having a similar issue but think the vacuum leak is also affecting my brakes vacuum booster. Sometimes my brake pedal become stiff and hard to depress. Wonder if it’s all stemming from my intake gaskets
thanks for the part numbers and tips!
That's a clean Tahoe considering the year.
Had an 02 z71 gave to me free of charge..fixed the rusted brake lines and the oil pump o ring..it wasnt missing but now it does but only on cold start ups like yours but it soon goes away..think this might be my problem as well...but i didn't watch your vid until after i had ordered 70 $ worth of new coil packs..oh well thanks a lot for the footage.
Lmfao 😂🤣😂🤣😂 @ 7:46
"SORRY IF YOU'RE IN MY ARMPIT RIGHT NOW!!"
Also all your comments and frustrations you make when you work on your car sounds like when I work on my cars. Lol.
😭😭😂😂🤣🤣 swear that proves we are human! I hate when I get stuff flying in my eyes and I'll tell myself that 'I don't need my eyes' because stuff is flying in them
O w that smell
This has happened to my Tahoe the same problem as yours and it was the intake manifold and also the rpm jumps up and down!
Love his comedy 🎭
Depo brand projector headlights is what I’ve ran on every Tahoe I’ve owned. They come in chrome or black.
Your video is awesome shows problems you would come across like dropping tools
Nice video, i got the same problem with my gmc sierra , im looking forward to do it , wonder how much would it cost to take it to a mechanic??
Enjoyed your vids ! as a owner of a 04 lt tahoe & 02 Silverado many things apply here for me. It’d been nice if you’d had the time to go ahead & pull/replace the oil pressure sender & filter below it while you had the intake out of the way as these are notorious for problems.
I was actually thinking the same thing when I was watching it.
My Tahoe does the exact same thing. Cool video
My we have a moment of silence for the extension and socket as they are in a "better" place.
Funny video Matt 😂 you’re killing it !!!!
Some suggestions for tail lights/headlights: silicone the housings so they don't leak/weep water. Try to avoid embedded LED lights so the whole unit isn't trash when they go out. The quality from 100 to about 300 are the same. Don't spend more than a couple hundred on all the light upgrades.
You should do OEM key sets and find that would be a good video!
I know this video is old, but there is a Schrader valve on the fuel rail so you can relieve fuel pressure.
Love the vids especially the tahoe vids. Are you a mechanic? how did you learn all these things
The green gaskets are the new better updated version of the old orange ones
Ray Romano fixes his Tahoe.
When you do buy your lights and taillights, don’t buy from DNA Motorsports from the L.A. area in California! They sell on eBay and their customer service sucks!! I’ve been trying to return a pair of lights for over a year and nothing. Great video by the way.
Hey I live in the nyc area and having similar issue with my 2002 suburban. I’m not 100% sure if it’s the manifold gaskets but pretty sure as the flashing engine light and rough idle goes away after my engine temp hits about 170-180F. I do t have access to a driveway or garage since city life lol but I was wondering if I got the parts and if you’re still in the area can you show me how and help? Obviously will compensate for time.
I have the same issue with my Ford Expedition, I did a smoke test and found out it was my manifold Intake gaskets.
Relay AND Fuel pump fuse. Some GM models also supply power to fuel sys as a weird backup
10 mm socket.. YUMMMMM the Tahoe has consumed it and will properly shat it out at 70 mph. Just to infuriate you it will make a loud noise whence shat
i love doin intake gaskets
New to your channel love your content in my dream project is a 87 to 89 convertible I rock I’d like to know your input on engine choice 5.3 or 6.04642 looking to say naturally aspirated I make 450 to 500 at the wheels
Sorry for the broken comment I am using voice recognition
Haha one of my favorite repair videos ever your hilarious
I bought a 2004 Chevrolet Express with the 6.0L engine and it has 107K miles. I have a P0300 Misfire and sometimes a P0200 Fuel Injector circuit codes that come and go. The misfire doesn't start until in has been driven for an hour and then the engine light comes on. The engine light flashes when I back off the throttle and stops flashing when I get back on the throttle. Looks like the plugs are new. Maybe the 6 & 8 coils have been changed as those are the misfire cylinders. Sometimes misses on #1 also.
I've seen where there are a dozen causes so you have to test until you find it. I need to find someone who I can trust to do a professional job without rebuilding the entire engine so for now I have to hunt for it. What do you think about the fuel filter being a problem? It probably hasn't been changed. I just put in a new air filter. Is there a "Most common cause"? Anybody? Thanks.
Any thoughts on direct air intake vs the stock with all the crazy shapes?
Mine did same thing but it wasn’t throwing any O2 sensor codes. I thought all the same things that I had intake leak, bad injector and other kinds of crap. What ended up being that ceramic in a 02 sensor had a crack in it. When the exhaust had condensation buildup like cold start or at a stop light it would act up. So when It acted up I started unplugging 02 sensors until it cleared up. That’s how I found which one it was but It never once threw a code for that. I found the tip on a old Ls forum.
Did you just replace the o2 sensor and not have the problem no more ?
@@elegantcaraudio yes. I was able to find which one was bad by unplugging it while it was running and it clearing up when I unplugged the right when it was having the issue.
So much for a “clean repair” lol wrong relay? The “steam line” serves 2 purposes none of which are anything to do with emissions. 1 it’s the high point of the cooling system, it’s helps with bleeding the system. 2 it apparently helps with warm up and prevents excessive frost and water moisture buildup in the throttle body.
are the stock valve cover gaskets blue or are those felpro replacements?
When I take my intake manifold off my trucks, I pull the relay and then loosen the fuel cap. I typically end up with minimal fuel at the rail when I disconnect it. Didn't read all the comments, so I don't know if someone mentioned this already.
P1175 is the code I'm getting and p420 any ideas if it could be the same issue, I already replaced the cat
The felpro gaskets I used had a metal base.
BIT EXPENSIVE, BUT, THE BEST!! I CHANGE THOSE ABOUT 1 YEAR AGO!!!, FUN AND ESAY TO DO
Would a blown head gasket cause the truck to sputter and die while driving?
Not only is there a torque spec, but there's also a sequence to tighten the bolts.. in case anyone else needs to know. They also recommend replacing the bolts too.
Oh...the sexual innuendos HAHAHA
Lol always a fight with the wayward extension.
Do yourself a favor and get the metal intake gasket it's right around $100. Better quality with a thicker rubber for a better seal. Fixed p0300 p0171 p0174. 2001 yukon with 266k miles. The lean codes were caused by vacuum lines. Especially the larger hose and seal at the front left side on the intake. That corrected the lean codes.
I hope the valve it's OK to much vacuum in there 😂
I have 2005 Chevy Tahoe and did my intake manifold gaskets, knock sensors, 1 coil, all spark plugs and connectors but still having some idle issues hmm not sure what's wrong I don't see any vacuum leaks or leaks of any kind.
I believe that maf cleaner works better for that stuff
Mines doing the same thing but knocking on the front driver side cylinder and stops knocking when I unplug that coil, swapped coil and still does it
Matty,
to save some cleaner. Use WD40 to do a basic clean. It will cut thru the grease/oil/dirt. Then finish up with the brake clean/MAF cleaner. Also isopropyl alcohol will cut grease and clean just as well.
And it's ALOT cheaper. You can buy a container for ~$3 at Rite Aid/Duane Reed.
to spray the gunk off the motor ?
Is your pass loc security system bypassed. I noticed the non factory key. My 05 tahoe leaves me stranded at least once a month. I have to do the 45 minute reset to get it started. About to send out my ecm to reprogram it out of there. Also check out my vid on broken tahoe drivers seat back.
I’m not sure, it came with only that one key.
Get video as always have you ever checked the purge valve
🤣🤣🤣😂😂 thanks for being human. Great video.
When it would have a rough idle at start up, would it sound cammed? Like a misfire but only for a minute or two.
what was your problem ?
Lol, the vacuum extension in the port
I went the hood cus the idle was really rough and I unplugged something and it seemed to fix it
Also remember to use brake clean to clean out sum gunk and coolant from belts. Easy job.
you need like a brief case to keep your 10mm sockets to store them in, always gotta be careful lol
I buy 10 mm sockets in bulk. Lol
Hey Matt. My 99 k1500 cranks up perfectly in the cold but if it’s hot outside it kinda hesitates to crank up sometimes. It’s very weird. Any ideas?
Check your ignition system
This video had me crying I was laughing so hard. Glad to see I am not the only one this crap happens to. You could just hear the fucker dinging around down there.
Get a pair of oe rep headlights and retrofit them.
What oil do you run
I'm getting P0-171 and P0-174. If I unplugged the mass air flow sensor it doesn't throw the code and idles normal. But it throws the code for maf sensor. Went and got a new maf sensor and did the same thing. Mine does it cold or hot at idle only. Driving down the road it's fine. I need help. It's driving me nuts.
You need to change the intake gaskets like I did in this video. It runs better with the mass air flow disconnected because that puts the tune in speed density mode which bypasses the maf sensor in case it fails. So basically the maf isn’t reading the pirate air being sucked through the leaking gaskets, so the engine does not like the unmetered air. P0171 and P0174 are lean codes for each bank.
Edit: It could also just be a vacuum leak from somewhere else, so check the intake tube for tears from the maf sensor to the throttle body. Also check the pcv and vacuum lines on the engine.
I had to do same repair on my 2004 tahoe.
Id change the knock sensors while you have it off and put sealer around while its apart
The slo mo vacuum penetration was cracking me up
Same BS with my 2001 6.0 LQ4 Silverado. Horrible rough idle/missfire @ cold start then 3 minutes later runs great
300,000 miles on my tahoe and still strong
What double din is in your Tahoe?
12:56-12:35 sounds of a true man
