Chasing down an oil leak on my 07 4.8, at first it was just a few drops on the driveway, but has now turned into a spot instead of a drop. It is very noticeable when driving first thing in the morning as the oil must be getting on the manifold, and smokes a bit on the drivers side when it burns off. I am thinking that it is most likely the valve cover gaskets, but just wanted to see if there is anything else I should be checking?
I have looked into the oil thermostat a while back, but this leak is higher up as it is getting on the exhaust.
Valve cover gaskets will be changed when I do my valve seal replacement, have been putting that off like the plague.....
