I don't know much about these trucks but the 1986 4x4 Gmc jimmy with a 6.2L diesel is this a decent engine? Would towing a car with this be ok? Anything I should know about them that goes wrong? Thanks.

Im no diesel expert but IMHO the 6.2 sux.
Low on power, and no GM doesnt recommend towing with them.

well actually uhhh they are about as good as a 350 for towing, super simple, have fuel injection, and will get you great mileage. but hey your no expert with diesel.

Thanks. Is 170k the end of the line for these motors? I rthink I can get it for 1000 bucks and it is a 4x4. Everything works.

Youre right, Mr Diesel expert, 350s arent available with EFI and are sooper complex:flipoff2:

Quit being bitches...it's Christmas.


The diesels can make decent power with some upgrades and a IP adjustment. The thing to look out for are the heads on the 6.2. Maybe we could get the REAL 6.2 EXPERTS in here but, until then...You Have to SEARCH!!

..try Google or the button 3rd from the right, in your current browser. :flipoff2:

Well, me and a friend put the exhaust manifolds, intake and turbo off a 6.5L out of a '95 Chevy onto his CUCV. Totally different animal. Seriously man, it doubled the power. I would look into this for the fact that you can get these turbo steups, or even an entire 6.5 for 300 bucks or less. The only mods needed to do the swap is to turn up the injection pump, new exhaust and a manual waste gate rod. Here is the people to talk to:

I have never personally owned one however I wouldn't pass up a decent truck because it had a 6.2... a few of my buddies have them with no complaints, not to mention better mileage than my 350

they are no duramax or cummins but still a great reliable engine, a few mods as mentioned above and you'll do fine

Thanks for the posts!

no. check your glow plugs and maby tune it a bit with timing or turn the pump up a bit

Youre right, Mr Diesel expert, 350s arent available with EFI and are sooper complex:flipoff2:

oh ya your efi smallblock runs with only 1 wire right and gets 20mpg. again you said it your self your not an expert with this motor, so why even state an opinion about it.



the 6.2L is basically going to drive similar to a STOCK 350 from the mid80's with a bunch of emission crap on it. its not going to be great but it will work.

Now that is a valid statement.
You don need to be an expert to know when an engine is unimpressive.

Had one in my dads 83 GMC short bed, I liked it. Didnt need a lot of power and it got pretty good gasmileage. Was pretty easy to work on. Only problem I had was getting the glow plugs to work correctly

I had a m1008 with a 6.2 th400 456s , 4inch and 35s, i changed it to 4:10s after that it got 18 plus miles per gallon. I drove it for years and it didnt cost me a dollar in upkeep besides (maint)fuel/additive, fuel filter, oil & filter , trans fluid and grease. Was a great truck in my part, hauled 2 ton of coal at a time 10 times a year. Its not the most peppy off the line but drove just like a 305 powered full size truck. I hauled alot with it and the 6.2 never let me down, needed glow plugs before i sold it that was it.......

Had the 6.2 in my last trail rig and in my current. Ill never go back to any other setup for trail only duty. Best STOCK option for a trail rig IMO.

Makes power low, run off one wire and fuel, simple and cheap to maintain, no carbs or refilling propane to mess with. Whats not to like?

Your fellas experience with the 6.2 seems to have changed my low opinion of them:beer:

Great engines. I would take the 6.2 over any other available engine offered in an 86 Blazer without question. They have no turbo in stock form so don't get in too big of a hurry. If timed right you will get 20+ mpg without a load and provide as much power as a TBI 350. A turbo makes a really big difference and they can be picked up for very cheap. I can help with any specific questions if you have any...

Why exactly do they suck? And what was GM's point putting them in 3500 dually's if they don't recommend using them for towing? :shaking:

they tow fine, especially with a turbo. its no hotrod diesel however, its more like a stout 350 if you have the turbo, maybe even like a very stock 454. Thats why i'm going to the trouble to put one in this '72, ans get 20+ mpg to boot.

for $1000 if it is as described I would have been on it like flies on dung.....especially if it is a cucv

We're gonna have to ask ya to be a little smarter next time.

There are many threads in here about the 6.2

Most either love or hate the 6.2

It's heavy, big, low on power, simple, fairly reliable and gets decent mileage. Quieter than a Cummins or Power Stroke and a decent 383 will dust it all day long.

I'm a little confused as to what you are saying...

I have built several 6.2/6.5's and I know their limits and what they are capable of. To say they suck and can't tow was a pretty bold statement on your part and was wondering if you could elaborate on that a bit. Wasn't trying to be a smart ass I apologize if I offended you.

If you would have read his post 2 up from yours, you would have seen that he has had a slight change of heart after reading what people with real life experince said

GMs own recommendation for the M1008s max towing capcity was the M416 which loaded weighs in at a mere 1200 lbs.

I think how well they tow is more a function of the truck than just the motor.

All things equal, would I rather two with a 6.2L or a 305? Gonna go with the 6.2L

But if the 305 has 4.56 gears and an OD trans in a dually, I think I'd pick that over a blazer with a 6.2 and 3.08 gears. Plus to me, suspension and brakes are more important to towing than sheer power

Remember back in the day, most Chevy trucks had a 235 ci straight 6 and they towed with those

But I'm not a big fan of the 6.2...
