I have never, in my recollection, seen an LS1 that smoked or had any other OBVIOUS problem that was not caused by neglect or over-modding (200shot on a stock motor, ect.).

I have also never seen anyone on here with a "Worn out" Ls1.

Oil gets low, a mis-shift bends PR's, juice blows one up, a bearing gets spun due to a cam-install or whatnot.

I have yet to see an LS1 just get old and die. It is always abuse or lack of care.

Anyone know of any stock-ish LS1's rolling around with 200K on them? I am SURE they are out there...

Just curious if I am blind to something or if it is indeed true that LS1's last practically forever if you dont mod the **** out of it or neglect it. I am at 80K miles on mine and it seems to be mint. I see guys on here all the time with mid 100's on theirs and no oil consumption (above regular LS1 usage) or any low-pressure issues.

I even see 100+K mile dyno's on STOCK 6-speed cars putting down 295-310whp...more than some made with 10K miles on them. Like the thing doesnt even WEAR.

On most cars at around 100K the timing chain goes or something, but I have never heard of this on an LS1.

Is there no "weak point" on these motors, or am I imagining things?

if you keep your car 100% stock, then I would expect it to last very very long. However once you start modding, look out for:

1. #7 cylinder
2. pistons
3. oil pump (mostly on older cars)

My point exactly, has ANYONE EVER seen an LS1 kept within factory guidelines that "wore out" not due to lack of care or low oil or something user-related? I have not.

I found a thread on CZ28 that one popped at 250k or 300k miles... Can't find the thread, nor do I have specifics.

Otherwise, I've never heard of such a thing..

Has anybody ever kept one that long without modding it?

i mean internally stock.

I've heard stories from Scott Settlemire about test beds that GM used for longevity that had 250k-300k miles that ran just fine. It is possible.

in my opinion they will last a good while if you keep good maintence on it .but then again i had a 99 30th anny trans am with 100k on it clean title and had it 3-4 months before it started knocking and etc.but that car was beat on hard.and wasnt keep up to well sat for year no starts, no regualar oil changes or plugs .
