I'm presently looking into buying a 1988 GMC Jimmy 2.8L V6 4x4. I was wondering if there is anyone out there who knows if 230XXXkms is alot for one of these particular vehicles. I know several people who have had the same vehicles but had the 4.3L V6 engines and they lasted do the mid/high 300 000km range. As well i would like to know if it is a reliable engine such as how long parts normaly last and such. Thanks.

I used to have an '84 S10 with 842,000 km's on it, still ran like a top, and yes it also had the 2.8L V6 in it. Just an awesome engine, total workhorse. :thumbsup:

I just sold my blazer with a 4.3L V6. It has just over 340,000km and ran great!
My buddy had a couple 2.8L in blazers and they lasted forever and took a beating!!!

The GM 2.8 60*V6 is excellent,.. lots of torque for a small amount of HP

They can take a beating too.

Keep it maintained and it'll last you forever.

Just many small things may go,.. like the usual sensors and etc,.. worst case,.. a power steering pump!

I knew a guy that tried to blow one of those up by over-revving,.. thought he did,.. but just skipped 2 teeth on his timing chain

Everything I have ever experienced and read about the 2.8 has not been good. I am not sure why all these people are saying it is great.

Do a quick search and your will see it is way under powered.

GMs 3.1 and 3.3 V6 engines of the same family are much better.

Yeah the 2.8 is definitely not a HP monster,.. infact very under powered that way,.. but for 130hp and 165ft/lb of torque it does have enough for a work truck.

These engines are starved for air flow, not relly worth tuning,.. but for overall general reliability,.. as long as you have the resources it'll be good to you.

Mechanically it's a fairly sound engine,.. just everything around the engine, that makes the engine work is what goes.

warning,.. you'll be better off doing repairs yourself,.. and many people can give you a step by step,.. not worth taking to a mechanic

I had a 2.8L in an S15 and it was totally underpowered. On the other hand, there was over 400,000kms on my Chevy Astro with a 4.3L in it back in the day.


But if you do regular maintenance, it should last a lifetime. Should.

I have a 85 blazer with the 2.8 and I get about 30 mpg on the highway its a 4x4 and although it has barely and hp it has a fare amount of torque. I was surprised the mud i could go through and the hills I could climb. But im gonna be putting a 350 in her really soon.

The 3.1 & 3.3 never came in the trucks. GM went from 2.8 to 4.3.

I'm not sure but I think it's the same 2.8 that was in the Cavalier Z24's in '88 & '89.
