In the last two weeks, I had the rear main seal and oil pan gasket replaced on my 2007 5.3 Avalanche. Replacing the rear main first reduced most of the oil leaking, but a week later the oil pan gasket was replaced to rid the remaining leak. After a 300 mile trip this weekend, I see no sign of oil leaking. Good for another 150K miles.
