LS1 w/high mileage in here, should I worry? My 99' LS1 M6 has 120K. I got the car at 112K. It was driven by an older lady and completely stock...its not stock anymore. Doesn't seem to make funny noises. I'm only worried about the engine/tranny related stuff...important things like the Oil pump, water pump and power steering pump. I take the best of care with my car. I drive it daily and don't get on it often. I'm hearing all these things lately with blowing motors/spin bearings, rebuilts and I can not afford that as i'm a college kid.
Whats your high mileage? Problems?

If you keep internals stock, I wouldn't worry with proper maintenance.
If you have the car maintenance history you can find if timing chain/pump were changed.
If not doing it would be good.
You can do a compression and leakdown test to establish shortblock health status.

I have 126k on mine and still running strong. I did headers and cam at 112k. I may do heads next year.
If the car has had regular oil changes and been taken care of you can go for a long time. I get on mine hard still and have had no problems.I have no plans on going into the shortblock until I have an problem (or get bored).
There are issues with the oil pumps for some years, including 1999. When I put my cam in I put in a new oil pump and the pressure went up. It may have been fine before. Do a search on oil pumps and you will find out more than I can tell you.
Otherwise, just enjoy it. The rev limiter is there for a reason, don't be afraid to find it!!
Good Luck!!

I got 90k on my '00. Heads and cam, and I beat the hell out of it. It burns oil from the rings cause they never got replaced, but it runs great and strong as ever.
