It seems everytime I start a new thread, it always has to do with my car being disagreeable lol. So, after trying to do a valve seal job with compressed air or pulling the head, I dropped a valve(the last one at that ) so i pulled the head to put it back it. I figure since I am there, why not put a new head gasket in, makes sense. I clean all the shit on the head and black, put a new one in, dip the original bolts in oil (like the book says) and torque them do in the proper sequence. The car ran ok for a bit, now runs like shit and has oil slowly leaking from around the head. I figure its leaking, any ideas to what I did wrong/ how to fix this?
