the shop rebuiltiti for the previous owner, called them Friday, waiting to hear back from them.

I know it was #2 injector fuel line as it took 4 turns to tighten the line. This engine in various forms can give a lot more power so I was hoping the bottom end stayed in one piece, I'm still going to try to pull the pan and have a look but oil pressure seems fine, if the gauge works properly. I'm sort of suspicios the oil light never came on when I was driving

My concern right now is the injectors or the pump as i never worked with them. could either give loud hammering noises?
