Re: LOW TENSION BACK TO STD TENSION OIL RINGS
in 2002 GM put low tension oil ring expanders in the corvette engines but with a plain second ring. these engines used oil and the fix was GM replaced the second ring with a napier styled second ring and a new oil ring but kept the original top compression ring. my 2002 corvette engine used a quart every 3000 miles but I never had the fix done.
