I am fixing to replace my tappet cover gasket as it has decided it wants to leak quite a bit. Before it was a 1 maybe 2 drops on the ground total and now the side of my block is black and it leaves a bigger puddle of oil than what i would like too on the ground. Not very much still and oil level is checked to make sure its safe! But, I want to know if I can purchase this 12v tappet cover off ebay and bolt it right up with a new gasket? Or will it not work? I Want the extra vent and c ant jar loose of $300 for a billet one.
