I am in the process of replacing my head cover gasket. For the cover to come off i need to remove the right side engine mount. The problem i have is i cant get the engine mount bolt out. Does the bolt have a factory lock tight? I twisted an allen wrench and used a 2 foot pipe for leverage, and it seems to not budge at all. I am considering using my air compressor, but i am worried about snapping the bolt in the case. Anyone ran into this problem? Any ideas?
