| Excessive oil consumption at or above 1 quart of oil per 1,000 miles. all plugs fouled out at 39,000 miles and one plug cracked. i change oil every 3,500 miles and regularly top off oil. there is no leaking oil but it is somehow vaporizing rapidly. there was no reason for the vehicle to fail like this at this stage in its life. chevy has come to state in a bulletin concerning a tweak to the valve covers to keep the oil from vaporizing. chevy has even more recently come out with a recall as of 1/17/2012 to announce there is a legitimate issue with the oil consumption on this model chevy. this is unacceptable and gm should pay for any current damage to the truck, worn parts and all. | |||
