Hi,

It depends on wich motor you have. If it is teh 5.7 v8 it is most likly stuck oil rings on one or two pistions or your possible your PCV is clogeged and not working. If it is the 5.3 aluminum V8 I would check the PCV First as it was revised by Chevorlet twice. If you get one go to the dealer and not your local parts store. If you could help me with a question i will give you a copy of the product for free.

Have you checked your Oil Cooler lines for leaks? I had similar symptoms with my 1998 Tahoe until I changed both the upper and lower cooler lines. Problem Solved.
