View Full Version : How many miles has your LS1 gone without having to overhaul it?

A little over a year ago I got my 2002 B4C with roughly 210,000 on it, and about a week before I picked it up, I posted a thread asking about using seafoam on an engine with 200,000+ miles on it. I got some helpful insight and ended up seafoaming my engine and had great results! The engine idled smoother, and sounded better. I was just re-reading my post and found an interesting question (especially since my car will turn over 250,000 by the end of this week), and after reading the "Official odometer/mileage thread" it made me wonder even more.

This is the quote from over a year ago
But with 200k+ already on the car....I don't know how much of its "high performance" will last. That raises another interesting question. How many miles has your LS1 or LT1 gone without having to overhaul it? Mine popped a little over 100k. I wasn't the owner then bought it after they completely overhauled it.

I'm the 2nd owner of my SS and the original motor lasted until 91k with 84k being the mileage I bought it with.

I know what you mean, at 250k a rebuild is in my future as well, and since the motor will be out and about, may as well add a few extra "goodies" to it :twisted:
But when the time comes I am also considering swapping in an LS3 or GMPP LS376/480 just depends on $$$ when the time comes

My LT1 has 174,000 on it right now. Still pulls well and runs great.

The secret is to drive it like you stole it.

That is so so true about lt1's. I'd treat mine good and the shit would break. I have 111k and still going strong!

I have an 02' SS with 137k that still runs like new. No leaks and I hope to get to at least 200k before a rebuild. I put @ 30k miles a year on her a year so I a hoping for the best.

You guys that have 150k+ are your cars modded? What mods? How long with mods?

That's the thing, once people start opening them up there are many things that can go wrong and hurt the life of the engine if done wrong.

I forgot I've got 100 shot wet kit on it too, but I don't shoot it much because my tires are gone. No tranny rebuild, I have all maint records.

Mine, is on its last leg, motor AND trans. My tahoe has 175K on it and still runs good and my 5.3 S-10 runs way harder than my 350 S-10 did. If I don't wait 30 minutes or so my 60' will fall off (about a tenth) so I think the trans is hurt for sure. I can't be more satisfied with it though. You just can't expect more IMO.

170,000 plus on mine and it still runs like a top. The rear diff is on its way out, but my mwc 9" will fix that. I am pulling the motor for a stroker soon, but plan to put this motor in another project, so it will live on!

Funny I find this thread, after a 150k mile ls1 hydrolocked a buddy and I have been trying to find a replacement. We put in an ls1 and got rod knock bad bearing, we bought an lq4 and found a bent rod. So after that much bad luck with all the ones we bought, we turned to the 200k mile ls1 pull out sitting in the garage that ran good from a parts car. So we will have it in and running by Sat. So not only has it lasted 10 years and 200k miles, we actually swapping it into a car haha.

Bottom end looked good, checked under the valve covers and all was well. Turned over by hand with plugs out and just a lil effort. Everything was a little dark from the miles, but looked great.

165,xxx on mine and still going strong. I want to cam it, but I know I shouldn't with the mileage. Might swap in a 6.0 then do it. Decisions, decisions...

go for it. just put a new oil pump/chain/lifters in and get a good tune. if the motor were to let go down the line you can reuse all the stuff you put into it.

'99 Z28 M6 w/ 246K miles on it. Original engine and trans. I've been good with keeping the fluids fresh. No engine mods. Daily driver averaging 26.5 mpg on my 120 mile round trip commute.

The driver's seat is worn out and ripped, it needs new lower control arm bushings and ball joints, and I've got an oil leak from behind the intake. I'd like to get these items all cleaned up this fall.

Probably the OPSU,do an LS6 intake and new knock sensors while your in there.

115K here. My car was definitely de-modded when I bought it though. Unsure how hard it was driven before I purchased it with 110K miles.

Added full exhaust, LS6 intake, and some misc. crap @ 113K miles. Still makes me nervous, but I've accepted that I'm going to blow her up one day and I'm ok with it. Got my eyes on a AES 390 build.

Well... its been just over a year since I opened this thread, and at 264,441 miles my head gasket sprung a leak on the drivers side (steam shoots out the front from between the head and block), and the engine now leaks massive amounts of oil, through several small leaks throughout the entire engine, my power steering pump is completely shot (fluid completely drains out after about 2 days of driving it), and one of the pulleys (probably the power steering as well) squeaks non stop. :cry:

So the answer to my original question was 264,xxx mi. i could just try to replace the headgaskets, seals, pulleys, and power steering, but not sure how much longer the engine will hold out, so i decided it's time for a new one...

Time to save up for that LS3! :drive:

I just bought a 2003 Suburban that was used for transporting railroad crews and engineers...394,000... 5.3 still sounds good...trans and transfer both shot. Seats, carpet, steering wheel very well worn.

(This 5.3 is going in my 1972 Greenbrier Chevelle wagon. I'll report back when it gives up.)
