Can't help much on the rest, but chances are previous owner is right on target with the blown head gasket. Sounds like it blew between the back two cylinders. Two low cylinders with about the same compression is the classic sign of a head gasket blown between the two. One cylinder is basically filling both on hte compression stroke, and the adjoining cylinder is going down on the power stroke as the other is compressing. --------------- Date: Tue, 24 Jun 2008 08:37:24 -0500 From: "Garry Nordstrom" <gasnordstrom@xxxxxxxxxxx> Just bought a 89 cherokee, w/258, back 2 cylinders pushing 30-40 on compression check, previous owner says blown head gasket, I doubt it, your thoughts, nice body, new tires, was worth the $100.00. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
