I was under the truck yesterday and noticed some wetness ( actual oil drops) around the rear area of the oil pan. Has anyone had problems with this? I run Amsoil, could the synthetic oil be causing premature gasket failure? I will try to post pictures.

 

could be coming from the breather and spraying around, or some have had problems with the valve cover gasket leaking and running down the back of the block and spreading...
