I have a 2008 chevy avalanche ltz with the 5.3L v8 engine with adaptive fuel managment. It was purchased used with 120k miles. It became apparent that the engine was consuming oil, 1-2 quarts per 3000 miles. Recently the engine started producing white/blue smoke on start up and oil consumption increased to 2-3 quarts in 1500 miles. My vehicle is currently at a mechanics shop and I am told that for starters I will need new valve covers that are redesigned from the original ones and that excessive oil consumption is...

My wife drove the truck to walmart to get a couple of items with her were my son in law and daughter. Once arriving there(approx. 3 Mi) they noticed some smoke coming from under the hood. My son in law opened the hood to discover a fire, he then ran into walmart where an employee grabbed a fire extinguisher and put out the fire. After they got home I checked it out and the wiring harness that goes to the mass air flow sensor was completely melted. It was still in all th he factory tie downs and wasn't touching anything that could have chafed it or pinched the wires. The truck was on city street then in parking lot

The active fuel management (afm) system has failed causing the motor to lose combustion in one of the afm cylinders (cylinder 7 to be exact) due to the afm lifter failed and has jammed the exhaust valve open.

Excessive oil consumption. It the 5.3L with active fuel management system. Gm knowns there is a problem and the only fix is to replace the rings and pistons or replace the entire engine at the owners expense, 5,000.00 - 8,000.00. Since it's it's a design flaw, I feel they should fix it at no cost. It consumes over quart and a half per 1000 miles, both highway and city and at times 2 quarts with pulling heavy loads. I have done a oil consumption test with the dealer and they have admitted it goes through a lot of oil. I bought the truck used, and the dealer who sold it to me never mentioned this truck could have this problem.
