Mileage
I posted this in the C5 section ,but figured that I should have posted here. I have a chance to buy a 98 with 82K on it , the body and interior are good. My question is at what mileage can Iexpect to rebuild and how much would it cost. I want to make an fair offer as the guy selling knows the milage will affect the selling price. Didn't want to post where the waxers that never drive their car are ,figured you motor boys would be better. PS the car was well taken care of. Thanks in advance Jim.

Re: Mileage (Jim D)
There are numerous variables that might affect how long it would go before needing a rebuild. I'd expect 150-200K from a well maintained, and not abused, modern engine but luck is also a factor and there is no way to accurately predict how long it will last. Often as not, engines die before they "wear out" due to an unanticipated failure of one component that causes severe damage to the rest of the engine. Unless you just want to rebuild it for your own reasons, I wouldn't worry much about having to do so soon.
The cost difference of mileage, as it pertains to the value of late model cars, is pretty well established by the pros. The Kelley Blue Book site can probably answer your questions in that regard. http://www.kbb.com/

Re: Mileage (oldace84)
Depends on how well it's been maintained and how it's been driven. If the owner has at least followed the OEM recommended maintenance, and if it's seen fairly high average trip length (probably has with higher than normal mileage), you can probably figure on 150K miles or more.
I don't know if the LS1 has been around long enough to characterize the wear patterns, but on most engines, valve guides are usually the first thing that need attention followed by cylinder bore wear. Bearings last forever nowadays.
One thing to consider is that the early LS1s cannot handle any rebore, but the later versions might be able to take .010", which means a major block rebuild will probably require a new block.

P.S. If you can agree to a price you might want to make it contingent upon an inspection and pay for a leak down test. Also, query the owner carefully about the current rate of oil consumption and check for oil leaks. If the leakdown numbers are good and it doesn't leak/consume more than a quart of oil in 2000 miles, and you don't plan on putting 20K miles a year on it, then it might be a good buy for occassional use.
