Ok guys, as the title says, I have an 89 XJ with the 4.0. It has been sitting for a month or two because of overheating issues. I got a buddy of mine who is a mechanic(bullardbs) come by and check it out. After some investigation, we found out the head gasket was blown, so now I have to put in a new head gasket. Any tips or pointers on this would be very appreciated since I have never tackled anything like this. Thanks in advance, Jon(deereman)
