Oil leak on my truck has me stumped. A few weeks ago I had posted that I changed the valve cover that came with pre installed gaskets on ny 3.7 F150. All is well no leaks. I noticed a few days ago that oil is pooling near the lower VCT grommet on the drivers side (side I changed). Stuffed a paper towel in there gently with a screwdriver and soaked it all up, fast forward to today full of oil again. Valve cover was torqued to spec and no oil coming from anywhere else. Any ideas guys?
