I got a PLOG and i installed today all the bolts except, the higher one next to the dip stick, went in without a prob. This one didnt seem to want to sit in the hole properly or catch threads yet all the rest went in flawlessly. I spent half an hour to 45min trying to get it in and evtally said screw it. Drov a arrond gave it one hard run and everything seems fine. Do you gys think im safe?
