Review on LOSTAR Valve Cover Left - 1999-2008 Cadillac GMC Pontiac 12570427 (with Gasket & Bolts 264-965) by David Alvarez

After years of intensive oil consumption, I heard about a defective valve cover on the driver's side. Recently just replaced the gasket and attempted to modify the factory cover I've heard about with a drill. Well it made the problem worse due to the extra smoke on startup. I often buy OEM but it has no moving parts and has great reviews and is less than half the price. I'm glad I did. I do not smoke anymore! Time will tell but I suspect oil consumption will be a lot better too.
