You need to describe where it was leaking, front, back, transmission end or accessories end. Did you use any RTV silicon sealant (what type as well) and what did you clean off the mating surfaces with?
What was the replacement gasket, Ford or after market supply and what was the material?
The gasket is a ford gasket. Second they did scarpe off the old gasket and resadue. I think now it might be from the crankshaft seal right behind the pulley. The is oil all over the left side on the chassis bottom of the oil pan. The bottom of the valve cover seem wet to what do u guy think? and how much labor to do the crankshaft seal ?
