So I have had the 451 going a couple times this year. Firstly on a carb and now on Holley EFI. The engine is now covered in oil, leaking from who knows where or maybe every gasket on the thing. Is it possible that the engine not having a pcv valve anymore is causing this? It didn't have it with the carb either. I'm just trying to figure out why all the oil all of the sudden?
