Oil...all over the front of my block...I think I'm going to cry...changed valve cover gasket, no help, cleaned and tightened all hoses and clamps, no help, the oil is coming down from what looks like the header side of the block, maybe I need a new head gasket... any suggestions? The only thing leading me away from the head gasket is that I don't have white smoke, therefore Im not burning coolant or oil...Is this a normal problem, or should I start to worry?
