Which engine prone to fewer problems?
From what I've read, the engine was modified for 2001 to squeeze out a few more horses, but that as a result, there were/are some oil burning issues that were subsequently corrected for the 2002MY. What about the engines that were supplied in '99 or '00? Granted, less HP, but if it were between a 2000 and 2001 C5, would I be better off going with the 2000 in terms of reliability and easier maintenance? I'm still shooting for a 2002 vert, but if I can get a better deal on a 2000, would I be unwise to consider it? Is the 2002 MY that much of an improvement, engine wise?
Best wishes,
Jeff

I can't answer your question directly, but my '03 has had no problems whatsoever. I normally go about 6000 miles between oil changes (that gets the oil life remaining on the DIC at about 25%) and it has used no oil at all in that time.

My 2000 LS1 had the oil consumption problem, but I think that was more of a rarity than normal occurrance. Other than that, the engine has been very reliable over its now 29.5K miles.

my 01 used 1 1/2 quarts of oil in the first 1000 miles so they put new rings in it and at 9000 miles they put a new engine in it becouse of scored piston walls
Besides that I have had about 10 other engine problems if I recall correctly.

My oo vert doesn't use any oil. It had 5000 mile on the last oil change and I didn't have to add a drop. The DIC showed 35% oil life remaining. There was only 5 hp difference between the 97 to 00s and 01 to 04s thats not enough to worry about, the difference in cars can be more than that. The 00s had the biggest cams in them from what I've read.
Be careful of the 01s and early 02s due to the ring problem. You can check with the dealer to see if the rings were replaced, if they were then I wouldn't be worried about getting an 01.

Oil consumption actually effected a small percentage of cars compared to the whole, and continued into 2001 production. It was caused by an improper gap between the piston and cylinder wall which exceeded the capability of the "wipers" to contain it. The fix, under warranty, was to replace/add a third wiper ring to the head of the pistons (from memory here). It required pulling the engine and the head. This would have been done only by a dealer and should be noted in the service records of the car. Any GM dealer should be able to access the records.

Keep in mind that not only did the HP & TQ increase in 2001, but there were significant upgrades in Active Handling/Traction Control, suspension, etc. Read the details here >>> http://www.corvettemuseum.com/specs/2001/index.htm

The minor HP differences on base C5's pre/post 2001 will be more than made up for by individual car performance and such small differences are likely made up by air intake/exhaust modifications by peoplel worried about the difference.
Go get a car. Love it. Drive it like you stole it for a couple of hundred thousand miles. Many pieces will fail during that deep duty cycle, but the engine is the most solid piece in the system and will probably keep right on ticking.
