They were Magnafluxed..on the bill stated. I talk to this guy monday, but I have the feeling he will try to get out of taking back engine to check it out..I hope I'm wrong..I supplied the gaskets, and they were very good ones..150.00 for the entire set. I'm just sick at this whole project coming down to a pinhole or a crack that he might have missed. Milky oil all over the grage floor..uggh! Bruce D.
