That's a common problem Joe! Go to http://www.mattsoldcars.com/techinfo/boltmod.shtml to find the best fix. A lathe is best, but you can carefully grind and/or file the bolt down. If using a grinder get a cup of water and keep it close by, dipping the bolt in the water after a few seconds of grinding. It will "hiss" for a second when you dip it, but shouldn't "hiss" for more than that. The bolt SHOULD NOT change color at any time! If it does you got it to hot and need to get another. A grade 8 bolt is all it is, so you can get a hardware store replacement. You'll need a 1/2" wide file or grinder though. If the engine was recently rebuilt it's poosible that the cam bearing oil hole wasn't properly aligned. Hope that's not the problem! -- Frank Swygert Publisher, "American Independent Magazine" (AIM) For all AMC enthusiasts http://farna.home.att.net/AIM.html (free download available!) --- original message-------------------------------- There appears to be no oil getting to the valve train and of course the valve clattering did not subside. The oil pressure idiot light did go out when the engine started. I then drained the oil and plan to pull the oil pan next to inspect the oil pickup and oil pump. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.wps.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
