One of the bolts holding on the front valve cover on my Pontiac G6 has disappeared, resulting in a bad oil leak. Easy fix, except for the fact that I don’t know what size bolt I need. Can anyone recommend a source for finding the size of the bolt? Thank y’all.

that looks bad
There was a bolt missing but it was unrelated there was so much gunk on the actual valve cover bolt that I couldn’t see them. Ended up being a bad gasket.

Pretty much any forum on your car or take out one of the other bolts and head to the parts store
