Is engine bad?
A buddy of mine has a 2006 Chevy Tahoe 4.8l with approx. 150k. His symptoms are blue smoke but not all the time, noisy lifters at startup and over time after warm up, burns about a quart every 500-1000 miles. Also has some loss of power since new(maybe normal). I have heard there are problems with the 5.3 cams is this with the 4.8 also? Thanks for any advice in advance.
