- I picked up a new rescue truck, a 1989 Chevy K3500. This beast is equipped with the big block 7.4 liter 454 engine. You have to love these GMT400 / C/K series trucks ! Like a ROCK :)..
WOW, Jason, that ione is KEEPER in the collection! You'll never find another one inthat condition in the North East... What a score!
Gotta love the ole 88 89 Chevy’s because of their moon gauges and I didn’t know in 1988 to early 1991 they had extended cabs with those gauges.
Jay, I will be first to say. I envy you for having this truck. A great OBS find. I've always loved this style and having owned one myself for 14 years they are a great truck and built to last in the right hands.
thank you JB5101
Amazing truck Jason, what a great buy. Keep it as is. Not too often you can find a 24 yr old vehicle in that condition. Congrats. God Bless
34*
let's stick with 24 years haha :)
I wouldn't do anything I wouldn't change that truck the way that is it's absolutely gorgeous special the cap that matches the paint they don't do that like that way anymore keep it all original
Great truck! Leave the top on to keep the bed from going bad + you can haul interior parts without them getting damaged from weather.
The smoke is white. Could be a lot of water in the exhaust from condensation and sitting. I would check for pressure or bubbles in the coolant reservoar. You could also check for CO in the water with a test kit.
If that's fine I would make a longer drive to heat the whole exhaust system up. There's no water in the oil by the looks of it.
its fine just let it warm up some, think l have some of the rims that are on it 3
you have everything lol
Great truck.
That will pull a house.
Beautiful truck! I'd start off with a compression test on all cylinders before you do anything drastic.
I have a 5.3 Silverado from 2014 with 75000 miles, and it makes a lot more noises than that 34 year old! My uncle used to say his 454 suburban could pass anything but a gas station! Nice truck, keep it away from the salt!
Do not flip the air cleaner lid and forget headers you will have perpetual exhaust leaks with headers especially if you tow with it . The steam you saw from exhaust seemed excessive but thats a big engine moving lots of air so unless it smelled sweet or like burning oil I wouldn't worry about it. Your right about the wheels the factory offset will get them back under the fender. You want to make sure the cooling system is in good shape as heat and excessive rpm are the big blocks biggest enemy saw it a lot in Class A motor homes . And a second mortgage for gas will be helpful. Beautiful Truck and only 50k miles you lucky dog.
Nice Truck Jason. Really hard to diagnose on a Video, Maybe flip the Belt off and spin the idler pulley under the Power Steering Pump, as it seems to be from that area. The Mrs Hopes no - one was sat in the Camper getting smoked to death !
Has someone who runs a 97 2500 HD as my one and only vehicle for many years now with a 454 I can confirm that I'm on a smoke coming out of a cold exhaust is normal and will not clear up until it's been up to operating temperature for a minute or two it is just moisture in the exhaust I loved it because living in the deep south always told my neighbors I'm just controlling the mosquito population lol or I called it my James Bond smoke screen can't catch what you can't see
thank you for the feedback , much appreciated . It only has like 53k and sat a lot so it's going to need some love
@@5150mxVW just a little looks mostly good to go to me Just in general maintenance
Nice truck. No irony in having a “bug shield” 😂
thank you ......🤣 :)))
Wow - a veritable torque monster! 👹👹👹👹 I have a 402ci BB in my '71 Chevy Monte Carlo, and ya gotta love these Chevy BBs. Jason, this is a nice looking rig for an '89... I definitely like the color combo. As for the noises up front, I'd take this puppy for a decent ride, then determine what is making noise from where. It could be an idler pulley/pump/alternator bearing - as some people have already suggested, if you can't figure out where the source of the noise is, you could disconnect the accessory belt, fire up the engine, and see if noises are still there. If not, the culprit is probably one of the units that is driven by the belt. The smoky exhaust? Drive it, get the vehicle up to normal operating temperature, and see if you're still getting lots of smoke. Could be lots of condensation in the exhaust system.
Hi, thank you for the advice . Turns out it broke a push rod … I have yet to pull the intake etc and repair it .
Amazing truck! I would take the serpentine belt off and hand spin all the accessories...It might be the alternator or ac clutch bearing or something along those lines .. super jealous
Absolute GEM 💎
Cap should definitely stay! I just bought one for my truck and I'm a changed man. Built a raised bed in the back and were 🏕. Look at all those windows to wake up to...
No wheel spacers they all stuck out. What another score!!! Like new that was really fancy in the day. Nice!! Especially for up here. Would definitely
do belts pulleys water pump fuel filter. She seems to be idling high but it could be a vacuum leak.
thank you, i did not know that. Yes it was idling high, thank you for the tips
Heck yeah! That 454 still put out 400lbs of torque.
Might be a cracked exhaust manifold…listen near the donut gasket too.
Valve seals probably with the smoke. Change oil and add a good additive. Grab some Lucas!
Great find….solid truck!!
Congratulations, it looks amazing for its age, leave the Top on it, will be a great rescue rig.
Great grab These trucks are tough if you take care of them they will take care of you!
That's a big score right there
That is a lot of smoke, mine did that for while after getting it then it went away, my guess was moisture in the fuel tank. because it was white smoke, and as you mentioned the valve seals were leaking, I put magical valve seal restoring additive in and it worked. that smoke was blue. it's all good now.
Leave it exactly as it is!
😁👍
Noise is possibly tensioner/ idler pulley….big on GM
Awesome find!!
thank you
Hey Jason, I’ve owned a lot of GM’s. That noise sounds like the smog pump. It pumps air so! And that’s not smoke, it condensation, it will disappear when it warms up good. Keep driving it. I got a 2005 GMC 2500HD with 55k. Everyone that sees it wants it. Thanks much for sharing your video!
Wow, that is really nice. How can't you love it?
I had a 1991 gmc sierra extended cab short box back in the day. Same red and black color scheme. Same red interior. 350 v8 automatic. I loved that truck! This video brings back a lot of great memories!
OK, first thing is you absolutely scored with this truck. Maintain it well, and it will live as long as you need a truck. They are very well built. Don't worry about the gas mileage, just compare that to what a new truck costs. Also don't change out the hard tune up parts until you inspect the old stuff. It may be just fine. But do change out all of the fluids. They degrade with time and/or use. Cheap insurance.
Now, I drive a 91 Chevy Scottsdale that currently has about 72K. I bought it with 48K about 5 years ago. Outside of the basic tune up stuff and wear items it has been fantastic. One thing that happened that I really want to share with everyone interested in these trucks, is the fuel pump can be an issue. Keep the fuel level above 1/3 tank at minimum. The "in tank" pump is cooled by the fuel, and they like to burn up if run low.
This leads to the next thing. A couple years ago I was in the middle of a 3K mile road trip in my 91 when it started to act up. Stumbling on acceleration, but always started and cruised just fine. Obviously starving for fuel. Long story short, I was losing fuel pressure. I finally gave in and decided to change the fuel pump. I cut a hole in the bed since I was at my dad's house and had limited tools. Turns out the pump was fine, but the 3" length of rubber fuel line connecting it to the tank outlet had begun to split, and was spraying fuel, thus dropping pressure. The new pump came with a new piece of rubber line that was modern fuel rated. Problem solved.
So, to all of those out there putting low mileage GM trucks back on the road, be sure to check that chunk of fuel line at your convenience, rather than at the side of the freeway with a trailer hauling your next great find.
Nice truck. I like that yellow 1303 Beetle (SportsBug?) too! 😉🙂
Thank you , yes good eye 😁
Take the fan belt off and run the engine without it. If there is no more "strange" noise then you know it is not the engine itself but it must be one of the auxiliaries. Good luck!
Love it. I have two on my boat. love that engine.
thank you Timothy....wow, it must cost you 500 just to idle out of the marina haha
@@5150mxVW Twin 454's
Luv it. We don't see those in Europe, ever, we get the odd pickup though living rurally. It looks well kept and I always love the US style interiors, you guys are more gutsy in the use of colour and chrome and stuff. I love the burgundy.
Pretty colors.....nice truck
thank you Todd
You lucked out on this truck! What a beauty.
Smoke doesn't look like oil smoke whoch would be blue-ish. Just water vapor from a cold start. It's a big engine so lots of cold start vapors. As forvthe mechanical noise, hard to say when listening to it on a phone. But it can't be much because a spun rod bearing you would hear much louder.
Could a be a collapsed lifter.
Maybe the engine would benefit from a good drige on tge highway where it and the oil can get warm. A cold engine is always hard to evaluatie and judge specially when it has stood around for a longer time.
Wow Wow Wow, Go out and buy a lottery ticket cos you are one lucky guy. !! Its just great.
than you Harry, I'll need it for the gas bill haha
They can have issues with cracked exhaust manifolds and the donut gasket between the manifold and the exhaust pipe. Fantastic truck !
Nice truck Jason. Looks well taken care of. I have a 2014 1500 Quad cab Silverado. Got 12,495 miles on it with a tonneau cover, bed liner and side step bars. It still has bar code stickers on the frame and shocks! Cherry shape condition.
Looks like a nice truck, well done Jason. I would suggest the knocking was that bar you pulled out? A compression test wouldn't do any harm. The oil didn't look 'milky' so no water in it.The smoke was not black so no piston issues. If it hasn't run for a while it could be condensation and the cold weather. I don't know these trucks, we don't have lots of them in the UK but I would check for belt change intervals. That is something people overlook. Hope she gives you good service, she's clearly been looked after. Once again well done Jason.👍👍
Over the years I've had 88 1990 mini in red color with the red interior I thought it was a really good redesign in 1988..... Remember is the first fuel injection or shall we say a box with a couple of spray nozzles in it.. of course around here they rot away but they rotted away slower than the ones from the 70s did in the sixties to
that's a camper shell, build a bed and heater, a cooker. Make that a camper
That just might be the nicest vehicle you have ever brought home! Most of those trucks were used up many years ago. Have not seen one with the original style dashboard for some time. Big engines with big exhausts make lots of condensation in cold weather. Might be nothing at all; unless the coolant level is dropping that is... Did it smell like sweet antifreeze or oil burning? Noise did not come through in the video, although as others have said it could be a leaking/cracked exhaust manifold or broken exhaust bolt. Or maybe a noisy lifter that comes and goes. Anyway looks like a great truck that should give decades of service if you look after it...
Dear 5150mxVW.
👍👌👏 Congrats! This good looking, big vehicle seems to be in a really great condition! Hope the gas mileage isn't too 😱 scary/frightening! ;-) You asked for information: I guess that Mr. Hevyshevy is the right guy to ask about those kind of pick up trucks.
Best regards, luck and especially health to all of you.
That’s a lovely truck . Def put steelies back on and leave as is after the service. Colour perfect. Great purchase Jason. !!
thank you , nah I'm rolling the old school american racing rims :)
Wow, that's less then 2k miles a year. If it's been sitting I'd change all of the fluids and drive it. Give it a chance to lube stuff back up good, work itself back in and then see what starts leaking or lets go. Nice old Chevy!
lol.. seeing what you come home with 99%of the time i think jen has a good reason for asking what are they hiding ...😀
Beautiful truck and so minty
thank you Max
Don't remove anything Jason🔧. It looks so great!!! John here, from the back-roads of Northeastern Tennessee. It's awesome.
Hi John, thank you
Beauty truck. Sounds like a pulley , do a tune up, bring it up to temp and go for some nice easy drives to get rid of the cobwebs and garage disease.
Looks like a good truck. Would love to see Jen driving it around your side roads on a sunny Sunday afternoon. May after wait a little while longer for that one bud. Keep on keeping on.
Sea foam the heck out of it. I'd leave it as is. The topper will allow you dry storage and bug shield is pure classic. As my wife would say....An old man truck.
leave it as is, as i'm an old man :)
That's just cold engine vapor! Idler pulling bearing definitely going. Speedo goes haywire on that style. Other than that those are great trucks. Up here on michigan the frames rusted badly on them.
Nice truck clean that’s been garaged change coolant also
Nice looking truck Jason ... Hopefully it serves you well ...
The front and rear track widths are different on those 4wd trucks. It's done that way so that the rear wheels aren't in the ruts the front tires are creating. It always bugged me but it does have a purpose.
Nice buy you can,t beat the older trucks I have 98 GMC suburban with 6.5 turbo diesel great truck
Nice, thank you Dennis
nice job.
Nice vehicle, I'm a little jealous. My opinion...remove serpentine belt. Check each and every pulley for sloppines (excessive lateral or radial play). All pulleys should spin true and not make ANY noises as you spin them by hand. Replace defective pulleys and the serpentine belt with new ones. As others commented, test all cylinders for compression. Put bottles of HEET or Seafoam in gas tanks until April. At oil & filter change time, add a bottle of ATP AT-205 Re-seal additive to rejuvenate engine seals. When engine sits (not running) too long, the seals don't get the oil on them to keep them tight. Thanks for another fine episode.
Excellent video Jason :) also a close friend mine had same color but was 1988 Chevrolet 1500 with 5.0 305 V8 TBI (Thorttle Body Injection 2 barrel carb looks like ) , Turbo 700SR 4speed Overdrive Automatic, with 377 rear end gears plus Air Conditioning, Cruise Control, Tilt Steering, Slider Back Window, Extended cab, tons power options even seats , long box of Z71 version and 2 wheel drive! It was Oshawa Ontario Canada GM plant number 2 built, that smoke be need Air Filter change plus PCV change also put grey bottle of STP Total Treatment fuel injection and carb cleaner in fuel tank too with 89 (5 % Ethonal or 91 or higher with no Ethonal % and oil Change use 10w30 engine oil no synthetic type plus oil Filter too ! If smoke doesn't disappear may need change Charcoal Cannister from TBI to Brake Booster on left back engine and fuel filter too ! If not it O2 sensors on exhaust on manifold or by Catylic Converter need both replacement too ! Also do OB1 test on computer see if code come up ! Maybe have Weak Injectors too or something!
These trucks were known for cracking manifolds. The brake light could be the ABS module. I had to bypass my ABS system. I could night find the module. Check out LMC online as well. That smoke is common when they sit awhile. Great truck enjoy.
For fuel system and or oil this is an excellently engineered cleaner
That truck looks awesome Jason! Great buy!
thank you!
Sweet truck! Nice score Jason!
thank you JP!
Used to have one, Exhaust Manifolds Cracking are common on them. Still a Awesome Truck, Would love to have it for myself. Now you can hook up the Trailer and buy more VW'S ! Your going to love the power and Torque, Gas Mileage Not so Much, mine was the same about 10mpg, loaded or empty, it didn't seem to care.
That's a beautiful rig Jason
Thank you , I do dig it 😁😁
Very nice truck. It'll pull your trailer loaded and not even notice. That engine noise means the stereo isn't turned up loud enough.
Thank you , oh so I can bring home bigger toys now 😎😁
I’d suggest a diagnostic stethoscope. They are great for isolating “floating” suspect engine noises. I’ve had a few low mileage older vehicles and my approach has been address what is obvious and then expect a process of repairs as the your initial mileage adds up.
Nice truck jay ... 454 big block air cover top flip over for better air flow those engine gotta keep in maintenance and swap exhaust manifold to headers for performance... Good luck I hope u keep it Chevy rules !!!!
First that truck is beautiful. Looks great with the cap but I think shes more useful without it maybe at a tool box instead.
You said its been sitting and since you need to do the tune-up and check all systems maybe you can and some of the reconditioning fluids and an Italian tune-up ans she will come back around.
You can always go deeper later but that truck is a keeper.
I will be honest these are some of the best trucks ever made to be honest. I have an 88 with a 305 v8 and a 5 speed. They are built very well. Valve seals are always an issue on the chevys. But they typically only smoke bad on startup and then it goes away. If you decide to sell this beautiful truck let me know!
I think it’s a cracked manifold. I had that problem on a truck of mine love the truck. I think that would make a good truck to haul motorcycles around in big super fan to your channel. Keep making awesome videos. Thanks.
Great find the only thing that is not good about the 454 is that they are not that good on gas but other than that they are wonderful you got a great truck so just in joy it and take care of it and it will last a long time so keep on keeping on
These are working beasts. I have a 93 suburban 2wd. It has 300k on it. We bought it new. You can't kill.these trucks. Mine is a 350SBC. I bought a 454 SS about 10 years ago. Man, what a truck. That was one that I wish I never sold. Check out Brothers online
Awesome! I have the same exact but singal cab and blue. I love it, best truck in the world! Can't wait to see more videos on it soon.
Nice 👍, thank you
@@5150mxVW 👍
Beautiful truck!
1 vote for cap on.
thank you RR
I personally would put the OEM wheels on that beauty. Go old school to locate noice. 3ft piece of garden hose to your ear and poke around. It should jump out at you. I'm jealous
That year 454 still has a plastic tooth cam gear in it ,at its age it might not be a bad idea to replace it,they get very brittle and when it comes apart you will have 8 bent intake valves real quick! Seen it happen many times
plastic !?!?!?! thank you for the heads up Randy
Beautiful truck! She's a keeper. Stupid hose belongs to some air pollution control gimmick? Check that idler pulley it sounded like it was noisy. It's hard to judge with a mic on phone or camera. Smoke? No, vapor maybe, it appeared to be dissipating as it went higher.
The only thing I can think of the fuel lines run in between the cab and the back of the engine now this was on the 305 sand 350s and when the cab out start to go it will pinch the fuel line but looks like that truck is in solid shape and you don't need to worry about that other than that I mean I think they go go go
Awsome truck😎🔥👌
Thank you my friend
Evening mate
That's a great truck in fabulous shape. I'm thinking that truck wasn't driven in the snow and ice. Definitely do a frame protection on it.
What a nice truck, better than the new ones in my opinion, exhaust tic maybe ?
thank you, I think it was the pulley but the rocker noise I was hearing the other day was gone
It'll go through gas like a fish through water, but where else are you going to find a truck that clean? Worth fixing.
Dude that thing is perfect, if you ever want to sell it send me a message haha
I wouldn’t worry about the condensation.
Pretty normal for a cold big block.
That's funny man, besides VWs I've got a 97 two door Tahoe (blazer). It made me fall for the gmt400s, they're great trucks.
342 good on hiway //454 does crack on manafold out side of engine
The front wheels sticking out is normal for the 3500. Nice truck.
thank you, i did not know that
Check to see if your losing antifreeze. Could be a head gasket.
I bought a 1993 4 dr 1 ton dually 8ft bed in 1994 with the 454 and a 411 rear diff. 10 mpg up hill or downhill didn't matter. My suggestion would be to pull the valve covers remove rockers and push rods. Check for bent push rods. If you know how, change the valve stem seals. But first run a compression test all 8 cylinders.
I was thinking that's why it's only got 50k miles, lol.
I'm going to agree with Gary H. down below. That motor (I call them motors) pushes a huge amount of air, and it is cold outside. So yeah, steam. As for motors. Detroit is not called The engine city. Just sayin. Besides, I'm old, so leave me alone. 😜
Change oil take out on the freeway see if it clears up by the way Super Nice Truck!!!!
That is a good one. The only thing is the Gas mileage is going to suck. The 6.5 turbo diesel would be better. I had one of those and it was a beast. Pulled all day long at 10 to 18 mpg. 10 fully loaded 9k empy 18....that 454 will do about 6 pulling same and empty 8 to 10. But the 4x4 will be nice. 4l80e is a good trans too. better than the same year ford. they were trash. Looks good because he kept it oiled. that truck Is MINT for an 89 New Englander
Nice truck. For a truck that big, you need some truck nuts hanging off of the trailer hitch. I think that I would buy one of those kits from an auto parts store that lets you check the anti freeze for exhaust gas in it ( for a bad head gasket. Sometimes a leak at the exhaust header can sound like its tapping. To me the smoke looked white, not blue.
Check the serpentine belt idler tension pulley.
👍👍
I think that I would like to own it, sir same color as my Harley
Lucas oil is pretty good about fixing dry valve seals,if that's what's causing the smoke.
Hey Jason nice truck get yourself a mechanic's stethoscope there not that much money looks like a doctor's stethoscope only with a long aluminum rod or probe (don't let Jen see it she might use it on you for buying all these vehicles) 😂 but get one and put it on and probe the valve cover exhaust manifold anything like the area where pulleys mount and you'll find your noise location don't probe moving parts like the pulleys themselves or get to close to the fan check the water pump though just be careful. The smoke you saw may just be condensation in the exhaust worse case its coolant getting threw a crack or bad head gasket. check the exhaust just take a quick smell see if it smells sweet and check your radiator and coolant tank level. I had a blazer years ago that when cold had a kind of low level knock on the drivers side which ended up being a worn piston skirt but when it warmed up the noise went away the car had almost 200k on it when I sold it and was still going until the last owner got in an accident and totaled it. Hey I bought a 1994 4.3 vortec with 63000 miles on it for the car because I thought I would need it and you know what I still have it why? well I paid $500 dollars for it and couldn't find anyone that needed one go figure. Well good luck Jason.😊👍
