I found out what might be causing the problem. As buckeyc stated in his post about the headgasket. It is similiar except the headgasket is new. The place that built my motor did a bad job on the block guard and the holes wasn't even lined up with the water passagegoing to the head. I going to have to drill some holes and see if that works. This company is a well know name in the import industry and racing also. You would think they would do a good job with all those equipment and s**t.
