First all i swapped in a motor i bought, put it in and it seems to have a miss. so i pulled the plugs and the number 6 plug wire itself was covered in oil... I check down in the valley and it has some oil in it. I cleaned it out checked my valve cover gasket, and then installed a new one cleaned everything put it back together still missing and the plug and plug wire has oil on them again and back in the valley.. I can't see anywhere the oil would be leaking into the valley. So any help or ideas what to check would be great thanks
