So i got the rare valve covers to help clear my roller rocker set up. But i didnt think about them not having wholes. Has anybody used these. If so how do you deal with them not have the oil filler of the pcv valve whole ?
Decide on what you want in the hole you need to drill. Often I have seen these used with breathers with tubes where the hoses run down to the collector or vacuum pump.
Grommet size hole has to be determined first. The fellas I met just used a hole saw bit in there hand held drill simply find the center of the hole, use a punch to create a dent to allow the drill bit a spot to sit so it doesn’t wonder around.
