have oil leak by valve cover. i was gonna change it a while back but was not sure if/or how i was suppososed to remove some canester looking thing.

anyway, think im gonna try tomorrow afer work.

question i have is, is there anything i can use to clean up the area before i swap gaskets?

something i can use to get the oil, muck, etc off. that way when i change the gaskets i dont have to have a mess there.

thanks for any advice...
