High mileage LS1 timing
sensei451:
Hello LS fans,
I have reason to believe that my LS1 motor has around 200k on it. However it runs absolutely phenomenal, no issues what so ever.
I did not inspect or mess with the motor before the swap, I just put it in there and it ran perfectly, no codes, 40+ psi on idle.
Recently I have begun obsessing about needing to change gears and chains on it to prevent a catastrophic event.
How are you guys thinking about this, are there any common signs of failure I should pay attention to?
FormTA:
I have no input but I am interested. Mine has about 150k and like yours, runs amazing. I am afraid it will just go boom one day when I'm on it.

Nothing wrong with preventative maintenance, but beware the dreaded scope creep!! BUT.... if you are replacing the timing chain, it wouldn't be much more work at all to swap out the cam. If you went with a mild cam in the 22x duration and maybe a 113-115 duration, you could pick up some very easy HP. But then you would be on the stock lifters..., then new head gaskets, and head bolts. 8)

LOL, Ryan I think you should change your screen name to 'scope creep' (meant in a good way, not a creepy way). Your always thinking a step ahead :-D

Lol, problem is.. what's a walk in the park for Ryan is not quite the same for us mere mortals. I'm honestly not confident any preventative maintenance of this caliber done by myself would solve or create issues.
Don't know how to proceed honestly, by 200k its due date for sure, but then again maybe the previous owners might have done it already. And motor runs great.. should I try to fix something that's not broken while risking messing something up?
It's a tough one.
