The previous owner really manhandled this motor when he put it together. Hopefully the head is ok. I'm trying to put new seals and stuff in it and one of the rear cam tower bolts is destroyed and I'm gonna have to drill it out. Extractors aren't doing it. Thing is I don't where to buy bolts, does anybody know where to get them? Junkyards are useless for 5m parts here. They only show up like once a year.. if that.
