I may be late to this fan club of comments. I have a 86 GMC Suburban 4x4 with this 6.2. 2nd owner since 45k miles and I have 1.1 million miles. Just installed a new injection pump and plan to spend some time in December to sand out rust in the corners. I have pulled lots of things with this beast, but speed is a favorite. Good roomy vehicle by all means.
Hello .. sorry for delay farming got me behind. No issues with parts at all. Napa and Ebay seems to have everything. Funny thing I have found..the US Army still has tons of these non-turbo models with under 50k miles. When my money get right, I am going to purchase 1 of those m1008 trucks. I believe the Blazers were m1009...same drivetrain and heavy duty leaf springs. I would paint it outside, add a piece of carpet inside, and a radio. A++.
@@andrewebanks325 great question. Having grown up on a farm, we always did 3500 mile oil changes, it was a 1 driver vehicle, tires and I did all the work, except tire rotations/balance at Sears auto. Sears was my 2nd maintenance record source...RIP Sears.😪 . It was also easy, cause you keep track how many times the odometer has tripped. Sears would print out the yearly history.
My 85 Chevy 4x4 had a 6.2 L Diesel I upgraded to the 6.5 L Diesel and bombed proofed the engine and it’s so much better I swear it runs for ever I’ve had the pickup for 10 years and I never have any problem since I do regular maintenance!!!
That legendary engine have a great fuel economy in its class and there were very strong built, almost in every old Chevy Van for sale here in Finland have 400 -800k kilometers behind..
Thank you for posting this. I had an 82 k5 with a 6.2 in it and I never changed anything on it and drove it for years before getting married and selling it. I just got a 85k5 with a 6.2 in it again a few days ago and love it.
My LaserDisc player also played right through the menu frame sequence on my 1984 GM diesel disc, because most consumer-market players ignore the Automatic Picture Stop codes that these discs use.
Have a '84 Van with this engine; installed a Banks Turbo setup and holly-cow !! whole new engine. GM's mistake was offering ANY diesel without a turbo; runs much cleaner and now fun to tow. The 700R4 trans is also a turkey behind a diesel; installed a NV3500HD 5-speed and problem solved.
Bolted right up and the tower comes right up between the G20 Van floor braces; just cut one hole for the tower. Trans was the HD version from 1990's pickups ( I bought it new from GM) . Used a LUK flywheel with a LUK clutch kit which includes special clutch disk that eliminates two piece torsional type flywheels. I had the set balanced since I hate vibration. Have 40kmi on this setup.
Hahaha that new venture transmission, was the only thing junkier than that 6.2.. and I am a retired gm tech.. don't run that tranny in 5th gear going at high speed, for more then 20 miles.. pull over and let it idle and cool down ever 20 miles, or use 4rth gear.. tranny has a design flaw, and you will fry it, if you run it hard at freeway speeds in the overdrive gear.. (5th or 6th, whichever it has) .. overdrive spins the main rear power shaft, 30% faster than the front input shaft.. the bearing between those 2 shafts, runs dry of oil, and friction welds the 2 shafts together.. freeway speeds for long periods of time, in high gear, is what does this. And that turbo, on that 6.2, is dead.. unless it's the later design, with the 6.5 crank in it.. external oil seal on the rear of the crank, means, it's the better crank..oil seal in the rear main cap, means junk block and crank. Good luck, glad it's you and not me..
ya the disks get worse at the end. I guess they aren't sealed perfectly and air gets into the seam. most of the older disks have trouble past the 20 minute mark. There is a segment before this on the disk I edited out.

If you had an EGR model you needed to find an air intake manifold off of a 1 ton truck. we had a bigger air opening if I remember right you got 10 extra horses just changing that part. then you turn the screw on the fuel pump and eighth of a turn, and it's a happy camper
You are right. I loved the engine when I had it in my K20. I was in Florida, holding the pedal to the floor for a trip from Texas to Georgia. I was clocked by Florida highway patrol at 83 miles an hour. I looked amazingly at the officer and said it must have been a downhill run as I just leave the pedal on the floor. He laughed so hard, I thought he was going to wet his pants, and let me go without a ticket!
I had a pretty dim opinion of these engines until I got a truck with one in it. Completely changed my mind, boy was I wrong. I have an 84 C20 J code 3.73 gears and 4 speed SM465. Runs with traffic on the highway no problem. It’s a little soft when the revs are real low but perks right up once the tach starts moving. If you have healthy glow plug system and follow the start procedure on the sun visor it fires right up in the winter. As GM stated It was never meant to be a heavy pulling engine, just a diesel option for a gas v8 engine. I think of it as a 350 with the power range shifted towards the lower midrange. It’s a bit buzzy and that’s ok, it’s an old truck. For a diesel it’s super simple to work on. Replace the balancer when they get some age on them and don’t lug the engine around and you won’t have to worry about the crankshaft. Maintain your cooling system and don’t run them hot and no issues with cracking. Use the engine as it was intended, maintain it well ( the maintenance schedule advises to change the oil often, as little as 2500 miles depending on use and for good reason. The oil gets pretty sooty quick ) and it will give you decades of service. Mine was owned by a factory and had a Tommy Lift gate on the back. They used it since new to haul all kinds of stuff for years and years. It’s almost 40 years old and runs great.
..What he was really trying to impress, at the beginning of the video, without actually saying it, was that this engine isn't related to the 350 Olds diesel engine, which GM was hoping to wash their hands of at this point...
All of the 6.2s I worked on had a stanodyne filter on the firewall of the truck. I have never seen a filter mounted on the intake until the 6.5 came along. The original filter had a glass case so you could see if there was any water or dirt contamination in the fuel at a glance. They were very expensive to replace and an aluminum version was available for much cheaper but didn't have the glass viewing capabilities...
A GM guy told me the 1989-1993 models were the better of these engines. Although most of the issues with cracked heads and blown head gaskets were from people over revving the engine when it was cold. I knew a guy who blew his cummins in his dodge because he lived about a 1/8 mile from the highway and never let his engine warm up and give it way to much fuel and blew the head gasket. Mind you it survived about 200000 miles and 6 or 7 cold winters and was never plugged in let alone warmed up or cooled down. If you operate the 6.2 GM/Detroit properly it can be a good engine.
Huh? A guy told you a bunch of crap.. heads crack from heat, not cold.. these engines were converted gas engines. Not beefy enough for the pressures of an operating diesel.. as a gm tech, I have replaced hundreds of these things under warranty... Usually a snapped crank.. the 6.5 had a better crank and some of the last 6.2's got the better crank.. if it has an external seal on the rear crank, it's the beefier engine. The junk engine, has the seal, built into the rear main cap.. but the 6.5 has busted many a crank too.. I have ran both, and I praised God, when Ford, came out with the 6.9.. that was a great engine..
@@zanefitch9343 come-on buddy.. it's a light duty diesel..by converted gasoline, I meant, thin block, weak crank, bad heads and bolts.. the list is endless
@@KBS117 the 6.2/6.5 and the 5.7 Olds diesel are NOT converted gas motors. They do not share any components with existing gas motors. If you were actually a GM tech, you surely would be aware of this???
The guy didn’t point out that this engine was also in some of the full sized vans. This Diesel engine was by far one of my favorite diesels even though it was discontinued before I was born.
My 1984 K20 4x4 that I bought used 22 years ago now has 235,000 miles on it, I've pulled car trailers, horse trailers, hauled a 12.5' Camper etc and it still runs great. Only repairs was an injector pump and a fuel pump. gets 18-20 MPH empty. Now your not gonna break any speed records with it when hauling that kind of weight but I can't bitch one bit.
My wife drove mine for a while when her vehicle was having issues. She called me one day on the way in to work and asked if something was wrong with the truck. It wouldn't accelerate and was surging. It was governing out at 73mph.
I had one in an 84 Suburban. Over 30 mpg on I-80, at 75. Those of you whom suffered through slow acceleration must've missed this segments section on the turbo encabulator.
from what i understand that some 70's heavy duty Diesel applications such as this were used for alcohol drag racing. it is said that the motor was "virtually indestructible".
Being an army helicopter mechanic. I’m accustomed to standard fasteners. I hate how they mix and match metric and standard. I would hope I could swap out the metric with standard fasteners if possible.
You know that is where I heard it from HAHAHA. I had just got done picking up one of these lifters off the shop floor and then watched this right afterwards LOL.
I have two, bought new in 1987 and 1991. I installed Banks turbos. No engine problems at all. One has 230,000 miles, the other 138,000 I know a guy who drove a 1987 GMC 6.2, one million miles. He used two engines to do it. As someone noted, GM screwed up by ever selling these without a turbocharger. The first thing I did was put a 4 row radiator in the trucks. The factory two row tubes didn't cool the engine enough.
+FCFordLord Definitely i have 6.5 Turbo them figures were off back in the day and hook your passat to 15k pounds hahaha different kind of torque and power.
Those that dont know much compare this to current designs and put GM down. I drove one tons when they pulled to about 2000 rpm then fell on thier face, ford included. This is why they force induce most now. It was plenty good if you needed a diesel in the old days. Hope you kids can make somthing in your life worth a dam in between blaming others and playing x box.
Gotta add that obligatory blame the kids statement even if it doesn't make sense! Well played sir. Also, while I love Detroit Diesels, my 4.9L inline 6 gas engine produces more horsepower and torque than this engine does. And my engine is in no way powerful.
@@superduty4556 I've owned both and loved both. The 300/4.9 was a guzzler in comparison to the 379/6.2. They both ran out of steam on the freeway, but always made it home with the load. I sold the 4.9 but still have the 6.2. Both trucks shared one problem- rust. Other than that they both did their jobs without complaints and with few failures.
I have a 1990 model with 400'000 on it not much power but a very good engine. Gona overhaul it in a few weeks found a turbo from a 1999 6.5 that should wake it up.
@@KBS117 again, I can see you have no real experience with these motors. That crank will withstand forced induction. If he is gonna be that worried about the crank, you can purchase a Fluidamper harmonic balancer that will completely resolve any crank issue
100% True... My Family worked at Oldsmobile Powertrain Division. It wasn't the only time Gas/Diesels came from the same block and had endurance issues... GMC Toro-Flow Diesels were built on V6 Gas Blocks... Go back to playing PlayStation children.
I have a nice 1987 V1500 Suburban with a TBI 350 that just won't hold coolant but other than that, a very nice and clean survivor I also have a tired old 1983 K2500 6.2 diesel powered truck. She's rusty and tired but the 6.2 is healthy so I think I'm gonna go ahead and sacrifice my 1983 for the greater good of the 1987
It's funny how many times he said "This engine has nothing in common with the other diesel made by GM." Even though he wouldn't mention Oldsmobile by name. And "this is an entirely new engine, it is not a beefed-up version of a gasoline engine." I wonder how much amusement the engineers at Chevrolet got over the Oldsmobile diesel problems. Seems like there was some inter-divisional rivalry happening here. This was long before GM consolidated all the engineering into GM Powertrain.
Just stating for the record, the Oldsmobile 350 diesel block is not the same as the gas block. Very few parts interchange between the two. And the DX blocks were very reliable, more so than the 6.2 and the 6.2 wasn't too bad.
@@mattlf9120 The Olds diesel block was quite strong. Andy Mannarino campaigned a pro stock drag car using the diesel block. He actually had to lighten it. The injection pump was the biggest problem with the Olds diesel. And there were many failures due to water in the fuel that could have been avoided if GM hadn't cheaped out by not putting a water separator on the engine.
@@andyharman3022 your right and diesel fuel has come a long way since then too. My Ninety-Eight diesel doesn't have a separator on it and I haven't had any water for 10+ years. I wonder if modern pumps at the station have water separators built in?
The 6.2 litre Detroit diesel was a good motor it was Gm fist full diesel engine which was different than the 5.7 litre Oldsmobile diesel which later evolved into the 6.5 and 6.5 turbo power in the early 90s people say the 6.5 was underpowered but then again parts were cheap and the 6.5 was fairly economical at the time and probably still is today
I posted on another video. When these first came out they were completely useless dogs. Non of the upgrades had came out and after the owner had replaced several head gaskets and its performance wouldn't let you pass a bicycle they would go find a junk yard gasser and have my dad swap em out. He had these things piled everywhere. Most were hauled off as scrap metal. I have several Silverado 4x4's with bad engines that I'd luv to have 6.2's in with all the upgrades to make them perfect engine. The only truth when they came out was that they got really great fuel economy , plus diesel at the time cost just slightly more than a bucket of mud. We ran the old Fords with the 6.9's and it seemed we were driving for free with the low price of diesel. The 6.9's didn't get the mileage that a 6.2 would but it still was a great day to own a diesel engine. Now I run around to gather old engine oil to centrifuge and run that because I can't afford the"real" diesel. The 6.2's like motor oil fuel as well.
He said that you should always cap the fuel lines when you disconnect them from the fuel filter. But he did NOT do this in his demonstration. And he did not quote a service part number for the necessary line-caps.
They need to put a couple turbochargers on it to really give it some kick. Then you could tow just about anything and have the torque to really burn the tires at take off.
ohiopower Well get stronger bolts up there. I hear one of the problems with this engine was the fact most diesel fuel back then had water in it. I guess stations wanted to water it down to get more money for less. Water in the diesel engine is very bad I hear.
The crankshaft would snap like a toothpick. They break cranks even with the Banks turbo kit that GM endorsed for them when they were new. And the Banks turbos only put out like 6psi of boost. They do give them a respectable increase of about 40hp however.
Justin Stearns I say part of the problem was the poor quality of diesel fuel. Back when these engines were new I hear they had water in the fuel. That is deadly for diesels. Also GM may not of had a water seperator but not sure on that.
no, they literally had toothpicks for a crank, the 6.2 and 6.5 are both notorious about snapping their cranks even when stock and they continue to do so to this day. Hell they had service bulletins stating how big of a crack their heads could have. Neither had anything to do with water in the fuel.
Might have been slow as a turtle, but the 6.2 Detroit Diesel was built like a tank. Put a Banks turbocharger on it and it'll definitely give it a much needed boost.
It also depends on the gearing. In the military,the M1008-M1031 CUCV's came from General Motors with 4:56 gears and wouldn't even go above a digit from 60 MPH on flat roads. But the M1009's had 3:08 gears and did 70-80 MPH with no issue. The Banks kit added 60 HP/115 TQ when installed and equipped. The military all ordered theirs as J Code engines which meant deleted EGR and higher power ratings,but were naturally aspirated. For awhile now I've been really wanting to add a Banks to my M1009 and see what it can do.
fuck the hp as it's a deisel especially. I'm a performance engine builder. when I heard 240 pou is of torque I almost spit my beer in my gf face. that's not even 1 lb/ci WTF ! ?
super pickle they used the same architecture as the olds 5.7. The parts inside were different, the block was so close to the same they were able to use the same dies as the olds gas burner.
Not really. When GM came out with the 5.7L diesel , it was a pricey option. After they blew up around 30,000 miles or so GM"s answer was to switch them back to a gas engine for thousands of dollars. So here you paid extra for the diesel and then GM had the balls to charge you full bore to install a gas engine back in. Class action lawsuit was filed.
most 6.2/6.5 owners dont know shit about them think they're smart, those engines were SOOOO reliable with so little maintenance to none, fluid damper@front crank, smoky exhaust? tranny fluid pint in fuel tank ever 5k/KM(detergent in ATF cleans injector ports and low grade american diesel from ports,also might kill your shitty bosche DB2/DB4 if you over do it, just brake the checkvavle on the top of the injection pump,(its a glass ball 3mm by 3mm) then your set for life, also if you increase fuel pressure @checkvalve by couple PSI you'll gain tremedous horse power compared to its limp stockforms) injections precup will also serve a role in MPG vs POWER, depending on your build you might want to investigate into those, also if you do turbo them you gotta have an EGT gage, because otherwise you'll overload the poor pig and cook it dry, much love from canada quebec, where our 6.2 starts @ -40 celsius unplugged
Torque was good at least. The early 6.2 was tuned for economy, and had small prechambers. Good for fuel mixing / complete combustion, bad for moving lots of air and fuel.
I may be late to this fan club of comments. I have a 86 GMC Suburban 4x4 with this 6.2. 2nd owner since 45k miles and I have 1.1 million miles.

I had one in an 84 Suburban. Over 30 mpg on I-80, at 75. Those of you whom suffered through slow acceleration must've missed this segments section on the turbo encabulator.
This engine came out better than the Oldsmobile 5.7
Had one of these anchors in my CUCV and a 5.7 in the Oldsmobuick.
how did you like owning the cucv?
The news has changed a lot in the years
sounds like the micro machine commercial guy at the end- maybe I'm the only one old enough to remember that?
I’ve got a 86’ Commercial Unit Cargo Vehicle (A Custom Deluxe for the military). Love that truck and engine. Gotta love this 80s awesomeness!
The last 30 seconds were great!!
Mine was in a 1982 1/2 ton Rolls Canardly. It rolled down one hill and canhardly made it up the next!
Wish mine looked that good lol
132.000 miles on it, Winnebago Brave and Runs great 💪
Nice video, Jason. Thanks for posting!
from what i understand that some 70's heavy duty Diesel applications such as this were used for alcohol drag racing. it is said that the motor was "virtually indestructible".
Being an army helicopter mechanic. I’m accustomed to standard fasteners. I hate how they mix and match metric and standard. I would hope I could swap out the metric with standard fasteners if possible.
GUYS THE LIFTERS HE IS SHOWING ARE THE SAME ONES USED IN THE 7.3 POWERSTROKES!
I was amazed with Bill from PowerStrokeHelp pointed that out!
You know that is where I heard it from HAHAHA.
I had just got done picking up one of these lifters off the shop floor and then watched this right afterwards LOL.
I have two, bought new in 1987 and 1991. I installed Banks turbos.
No engine problems at all. One has 230,000 miles, the other 138,000
I know a guy who drove a 1987 GMC 6.2, one million miles. He used two engines to do it.
As someone noted, GM screwed up by ever selling these without a turbocharger.
The first thing I did was put a 4 row radiator in the trucks. The factory two row tubes didn't cool the engine enough.
Amazing this massive 6.2 makes similar power to the 2.0 common rail motor in our Passat!
It is around 34 years old, afterall. Made to be a long lasting truck motor that got good mileage.
I have one in my 3/4 ton 4x4 and get 19-20mpg.
+FCFordLord Definitely i have 6.5 Turbo them figures were off back in the day and hook your passat to 15k pounds hahaha different kind of torque and power.
+compu85 your vw won't still be running in 35 years
+19504x4 No, probably not.
it's all about torque
If they just downsized a 8v92 or I guess make this into a 2 stroke with a blower and turbo, things would have gotten interesting.
They wanted to stay away from Detroit Diesel's willingness to incorporate unit injectors as they are more prone to runaways
@@detroitdiesel-vu3ig plus the 2 strokes would never have been to meet emissions
There are two downsized 8v92s. One is the 8v71 and the other is the 8v53. 👍
Drop bolts inside engine when removing them
This video is a priceless gem on god-like level.
The Ricardo Comet 5!
the end of that video reminds me of the 80's movie Max Headroom.
This is so soothingly 80s. We need to bring back the na Detroit diesel to Chevy. I would buy one.
I’d rather a straight axle first
I have one of these in my boat. Where should I attach the anchor chain?
The crankshaft
to your balls
The 6.2 and 6.5 have a huge following in the marine industry. You can rev them to 3000 RPM and they sip fuel.
the most reliable, simple, and fuel efficient v8 ever made
Those that dont know much compare this to current designs and put GM down. I drove one tons when they pulled to about 2000 rpm then fell on thier face, ford included. This is why they force induce most now. It was plenty good if you needed a diesel in the old days. Hope you kids can make somthing in your life worth a dam in between blaming others and playing x box.
Gotta add that obligatory blame the kids statement even if it doesn't make sense! Well played sir.
Also, while I love Detroit Diesels, my 4.9L inline 6 gas engine produces more horsepower and torque than this engine does. And my engine is in no way powerful.
@@noscopesallowed8128 300 for life
Interesting comment coming from an old guy blaming "kids" and playing around on TH-cam.
@@superduty4556
I've owned both and loved both. The 300/4.9 was a guzzler in comparison to the 379/6.2. They both ran out of steam on the freeway, but always made it home with the load.
I sold the 4.9 but still have the 6.2. Both trucks shared one problem- rust. Other than that they both did their jobs without complaints and with few failures.
A good engine. GM was the first company putting diesels in pickups, a fact many people seem to forget when they bash on this engine.
Where is the oil pressure switch located
I just subscribed to your channel and hello from New Hampshire usa
Thanks! I had a few more tapes to capture and upload, I hope to get to them soon!
I have a 1990 model with 400'000 on it not much power but a very good engine. Gona overhaul it in a few weeks found a turbo from a 1999 6.5 that should wake it up.
That engine can't stand the turbo.. you will snap the crank...
@@KBS117 again, I can see you have no real experience with these motors. That crank will withstand forced induction. If he is gonna be that worried about the crank, you can purchase a Fluidamper harmonic balancer that will completely resolve any crank issue
Add an intercooler..then you put in an adjustable mechanical waste gate set for 10-15 psi, propane/ alcohol injection at high boost..
I didn't mark push rods when I removed them. How do I know which side is up?
+juan fo you wont know lol only replacement ones are marked.
I looked and they have a different color on each end like one is gray and the other is a yellowish tone but which one is which?
Head side runs hotter..see which end fits perfectly into the lifter before installation..
1:44 so your not talking about the olds 350 diesels? Yeah, they beefed up a gas engine for diesel duty.
false
No not exactly
100% True... My Family worked at Oldsmobile Powertrain Division. It wasn't the only time Gas/Diesels came from the same block and had endurance issues... GMC Toro-Flow Diesels were built on V6 Gas Blocks... Go back to playing PlayStation children.
Worst diesels ever made in America. Boatanchors.
Was debating a 6.2 swap or a 6.5 swap. I think I have now decided
I have a nice 1987 V1500 Suburban with a TBI 350 that just won't hold coolant but other than that, a very nice and clean survivor
I also have a tired old 1983 K2500 6.2 diesel powered truck. She's rusty and tired but the 6.2 is healthy so I think I'm gonna go ahead and sacrifice my 1983 for the greater good of the 1987
Hi. Can you tell me where I can get parts for these engines in the UK. Thanks Chris.
Sorry, can't really help you there. Does RockAuto ship to the UK?
@@compu85 OK thanks anyway 👍
Qwal a potência dele? ?
130 hp.
My 83 Chevy C-10 pickup was not a problem the turbo 350 transmission was..
I wish I had this handbook
Haha. That little lifter is in everything. From the 6.5 gm to the 6.4 powerstroke.
The bore is larger than the stroke. I guess this qualifies as a sleep aid. All this bore....
Thank you so much for sharing!
The video was a bit worn out especially near the end but still worth watching.
Ya, the LaserDisc is failing. :(
Kwantwz HP? ?
I'm so excited I can't wait
So, what about covering the delivery lines from the injection pump to the injectors? are we safe to just leave them open?
Nice suit
Cleanliness is important when working on a diesel engine 🤣🤣🤣 the mechanics at the shop I work at are covered in grease and oil
It's funny how many times he said "This engine has nothing in common with the other diesel made by GM." Even though he wouldn't mention Oldsmobile by name. And "this is an entirely new engine, it is not a beefed-up version of a gasoline engine." I wonder how much amusement the engineers at Chevrolet got over the Oldsmobile diesel problems. Seems like there was some inter-divisional rivalry happening here. This was long before GM consolidated all the engineering into GM Powertrain.
Just stating for the record, the Oldsmobile 350 diesel block is not the same as the gas block.
Very few parts interchange between the two.
And the DX blocks were very reliable, more so than the 6.2 and the 6.2 wasn't too bad.
@@mattlf9120 The Olds diesel block was quite strong. Andy Mannarino campaigned a pro stock drag car using the diesel block. He actually had to lighten it. The injection pump was the biggest problem with the Olds diesel. And there were many failures due to water in the fuel that could have been avoided if GM hadn't cheaped out by not putting a water separator on the engine.
@@andyharman3022 your right and diesel fuel has come a long way since then too.
My Ninety-Eight diesel doesn't have a separator on it and I haven't had any water for 10+ years.
I wonder if modern pumps at the station have water separators built in?
@@mattlf9120< GM used the gas block, that’s the problem.
I've worked on the Automatic transmission in this senc it's insepction , the 700R4 WAS A BUGGER BEAR😭

The 6.2 litre Detroit diesel was a good motor it was Gm fist full diesel engine which was different than the 5.7 litre Oldsmobile diesel which later evolved into the 6.5 and 6.5 turbo power in the early 90s people say the 6.5 was underpowered but then again parts were cheap and the 6.5 was fairly economical at the time and probably still is today
It was a desperate move to mention it had nothing to do with the car engine based disasters of the 70's.
Nothing is interchangeable? Not even the air cleaner? Dayum
Nothing is interchangeable
Not even the fuel lift pump
0-60 in 6 days to week ! AH , the good old days .
I posted on another video. When these first came out they were completely useless dogs. Non of the upgrades had came out and after the owner had replaced several head gaskets and its performance wouldn't let you pass a bicycle they would go find a junk yard gasser and have my dad swap em out. He had these things piled everywhere. Most were hauled off as scrap metal. I have several Silverado 4x4's with bad engines that I'd luv to have 6.2's in with all the upgrades to make them perfect engine. The only truth when they came out was that they got really great fuel economy , plus diesel at the time cost just slightly more than a bucket of mud. We ran the old Fords with the 6.9's and it seemed we were driving for free with the low price of diesel. The 6.9's didn't get the mileage that a 6.2 would but it still was a great day to own a diesel engine. Now I run around to gather old engine oil to centrifuge and run that because I can't afford the"real" diesel. The 6.2's like motor oil fuel as well.
Phil Lowman
I run like 25% new engine oil and other new oily crap thru my vw diesel, it loves it.
@@MrTheHillfolk there's dual tank kits for switching over to fry oil/ whatever for VWs..a tank heater helps liquify cold fuel..
My Army Reserve unit had a bunch of humvees and blazers with this gutless wonder..Detroit Diesel
He said that you should always cap the fuel lines when you disconnect them from the fuel filter. But he did NOT do this in his demonstration. And he did not quote a service part number for the necessary line-caps.
They need to put a couple turbochargers on it to really give it some kick. Then you could tow just about anything and have the torque to really burn the tires at take off.
+Tigerfire75 Probably pop the head gaskets like a cork.
ohiopower
Well get stronger bolts up there.
I hear one of the problems with this engine was the fact most diesel fuel back then had water in it. I guess stations wanted to water it down to get more money for less.
Water in the diesel engine is very bad I hear.
The crankshaft would snap like a toothpick. They break cranks even with the Banks turbo kit that GM endorsed for them when they were new. And the Banks turbos only put out like 6psi of boost. They do give them a respectable increase of about 40hp however.
Justin Stearns
I say part of the problem was the poor quality of diesel fuel. Back when these engines were new I hear they had water in the fuel. That is deadly for diesels. Also GM may not of had a water seperator but not sure on that.
no, they literally had toothpicks for a crank, the 6.2 and 6.5 are both notorious about snapping their cranks even when stock and they continue to do so to this day. Hell they had service bulletins stating how big of a crack their heads could have. Neither had anything to do with water in the fuel.
Thx a lot for this informations.
Do you have another training videos for this engine?
No other diesel discs yet. I have some other gm discs that won't play and some Ford VHS tapes to import still.
Might have been slow as a turtle, but the 6.2 Detroit Diesel was built like a tank. Put a Banks turbocharger on it and it'll definitely give it a much needed boost.
It also depends on the gearing.
In the military,the M1008-M1031 CUCV's came from General Motors with 4:56 gears and wouldn't even go above a digit from 60 MPH on flat roads.
But the M1009's had 3:08 gears and did 70-80 MPH with no issue.
The Banks kit added 60 HP/115 TQ when installed and equipped.
The military all ordered theirs as J Code engines which meant deleted EGR and higher power ratings,but were naturally aspirated.
For awhile now I've been really wanting to add a Banks to my M1009 and see what it can do.
Garages literally made millions replacing broken down 6.2l with gas 350s.
That disclaimer in the beginning about sharing components with gm gas engines we all know that engines hes referring to
Back in the 30s Agin Hugh?
Does the 21.5:1 up for naturally aspiration
SuperRandom6013 did you not listen
what does that mean...aspiration?
No its because it’s an idi
doing everything not to mention the olds diesel
OMG IS THIS THE TURBO ENCABULATOR GUY??? BOSS LOL

He had to give the “this isn’t a converted 350 gas engine” disclaimer. Goes to show how garbage those were.
super pickle they used the same architecture as the olds 5.7. The parts inside were different, the block was so close to the same they were able to use the same dies as the olds gas burner.
130hp from a 6.2 litre engine. Meanwhile bmc in the 60’s we’re making straight 6’s with 100hp and only 5.1 litres.
Back when auto makers took care of they're consumers
The_Burchfield HaHa, you must not remember the junk they were putting out back then.
Hahaha, you can't be serious? I was a tech for gm, when this junk was produced...junk
Not really. When GM came out with the 5.7L diesel , it was a pricey option. After they blew up around 30,000 miles or so GM"s answer was to switch them back to a gas engine for thousands of dollars. So here you paid extra for the diesel and then GM had the balls to charge you full bore to install a gas engine back in. Class action lawsuit was filed.
most 6.2/6.5 owners dont know shit about them think they're smart, those engines were SOOOO reliable with so little maintenance to none, fluid damper@front crank, smoky exhaust? tranny fluid pint in fuel tank ever 5k/KM(detergent in ATF cleans injector ports and low grade american diesel from ports,also might kill your shitty bosche DB2/DB4 if you over do it, just brake the checkvavle on the top of the injection pump,(its a glass ball 3mm by 3mm) then your set for life, also if you increase fuel pressure @checkvalve by couple PSI you'll gain tremedous horse power compared to its limp stockforms) injections precup will also serve a role in MPG vs POWER, depending on your build you might want to investigate into those, also if you do turbo them you gotta have an EGT gage, because otherwise you'll overload the poor pig and cook it dry, much love from canada quebec, where our 6.2 starts @ -40 celsius unplugged
That must be the strongest engine mount in the world, lol.
Subliminal messages at the beginning gave me a seizure.
How can a 6.2 litre V8 only push 130 horsepower? Just how? The stone-age Russian tractor engines of 1980 were making double that .....
Torque was good at least. The early 6.2 was tuned for economy, and had small prechambers. Good for fuel mixing / complete combustion, bad for moving lots of air and fuel.
No aftertreatment bullshit, I miss these days
