I have an oil leak that is coming from the backside of the timing cover. It appears as though one of the studs that the injection pump goes on has fallen out. Can anyone tell me the size of this stud. I am likely just going to replace it with a hex bolt. According to some shops around here that shouldn't be any issue, but they couldn't really tell me what the bolt size was.

 

Sounds like the case is loose, I know mine was, tq to 18ftlbs.
