kileeman said:I had a dealer today tell me that the 2002 Z06 has oil burning problems just like the 2001. Is this true or does this guy just not know what he is talking about
My 2002 is much earlier than that ... built in early Aug 2001. Mine uses about a quart every 300 to 3500 miles if driven hard. When I was breaking it in (not pushing it hard for the first 1000 miles), it didn't use any oil. After break-in I started driving is much harder, and it will use some oil if pushed hard ... which is probably normal.JKLNHDE said:I own a very early 02 with a jan 02 build date. I drive it pretty normal and use around a qt every 3k miles.
So does GM say the 2002s have bad rings also? I thought it was the weak piston ring tension that was the cause of oil burning when over 3200 rpms. I think ALL 2002s had the updated rings (along with the coated piston skirts) ... so the only reason a 2002 and beyond LS6 might burn oil is because of a leaky valley tray (where the PVC system sucks from).KevZ06Torch said:I'm having the same problem.... READ the new Corvette mag (May 05)....it explains that all of the 99-02 Vettes (LS1 and LS6's) have this problem....(oil burning over 3200 rpm/ Cyl #2)
That's correct. I would qualify that and say the only reason a 2002 and beyond LS6 might burn oil EXCESSIVELY is because of a leaky intake valley tray. Most LS6 engines will burn some oil, and that's normal. My '02 burns a quart every 3,500 miles, which is well within normal range for any engine. More than one quart every 1,000 miles is excessive, IMO.I think ALL 2002s had the updated rings (along with the coated piston skirts) ... so the only reason a 2002 and beyond LS6 might burn oil is because of a leaky valley tray
