Very impressive everyone......it sounds like Mr. VLS has the record with 320,000 miles on the original engine and 400,000 miles on the body. Hopefully mine will make it that far.

Oil changes every 3,000 miles and other scheduled maintenance has kept mine alive for 218,000 miles. I've never had the engine opened for anything...original head gasket, intake, everything is original and running strong.

"Like a Rock"......was no joke

 

Guys, have faith in these motors... The GM pushrods (aside from ridiculous intake manifold gasket problems due to poor gasket material) are virtually bullet proof! I have my 93 z24 3.1V6 (60* V6) with 334000 KMS with no major repairs (water pump, valve cover gaskets, small things). My pops has a 95 Astro 4.3 V6 with.... wait for it.... 685 000KMS!!!!! All he has changed is his waterpump, timing chain for preventative maintenance, and regular maitenance!!!

Take care of these motors, and they won't let you down!

 

im at 197,xxx with nothing replaced but im goin to knock on wood cus i always do this to my self lol still running stong better then half of them out there ..

 

Got mine last week with 258K miles on it for 300 bux. Engine and tranny are strong

 

No! Nobody has more than your truck milage. LOL.

 

well i know someone with a 93 jimmy that has 290,000 i've probably got the reverse record. I have a 94 s-10 blazer with 88,000 mile on it. bought it with 72,000 miles on it

 

well ive got a 1997 and its got 273,678 and doing fine

 

hellz yea. the '95 is throwin down 192k and running strong here. I just got my a/c fixed and i had to replace both u-joints in the rear. there was nothing left seriously..

next, Ill be painting the rear plastics.

 

I have a 93 WT with a 4.3 in it and it has 222K miles on the clock. I just had to replace the Intake Manifold Gasket about 5 k ago but other than that no engine work. This truck was a work truck for 45k miles of its life In PA and i have no idea how it was cared for. Then by dad bought it and ran it up to 96k miles. He takes pretty good care of his stuff. He changed the tranny fluid and diff fluid when he bought it. He always ran rotella 15w40 in it. I bought it and it now has 222k miles on it. I take very good care of my stuff. I change the oil every 4 to 5 k and it usually gets rotella or a name brand 5w30. When my dad had it he used it to pull cars around and bring coal to the house. So the first half of its life has been pretty rough. Since i have had it i mainly used it for driving to collage and stuff which was about 20 miles one way of straight interstate and some l ocasionally pull my atvs ect but not very often. Im starting to get a little lower engine knocking upon startup but goes away after warm. Im hoping to get at least 250k out of it. Really i dont know if the body will hold up that long. it is starting to get a lot of surface rust on the fenderwells and stuff. Anyway i love these engines.

 

i have a 96 and it has 256,000 on it and i am just now havin problems with it. i think it is just a jumped timing . we will see when i get everything offthe front of the motor. up until this i ran it thru mud and everything with no problems.
