99-2000 Camaro,Firebird,Corvette w/ vin G or S engine.Subject:High oil consuption may be caused by faulty piston rings .Oil consumption may be one quart in 400 to 600 miles.The problem is found more often in cars w/ manuel transmissions where the engine is more likely to spend more time at higher rpm.New piston rings from kit #88894299 should be installed,but not the whole set.
Install only the number 2 compression ring .Leave the the original number 1 compression ring and the oil ring rails on the pistons.Do not dress or hone the cylinder bore.Changing the original bore finish may make the problem worse.Bulletin 01-06-01-023.
