I have 2007 5.3 Aluminum block AFM engine. Had oil consumption problem with mine from about 30k to 70k and getting worse. Took it to the dealer and they did a consumption study and they performed the first "fix"---the oil pan and valve cover thing. Didn't help at all. They then recommended the full job--new pistons and rings. Hasn't burned a drop of oil in 6k miles. Runs great. It was out of warranty of course. I tried to get GMC to pay for all of it but we agreed on 50/50. Figured it was worth it. Feel like I have a new lease on life for my motor now.
