well I found the problem. Its preaty bad. I had sleaves put in the spark plug holes because it blew a spark plug out not long after I first got the truck. I had them put in all of the holes because I didnt want to have any problems with it later. when I changed the plugs it pulled the top off of two of the sleaves. one in each head. I didnt think it would hurt. the threads were still there just the seat came out. I thought the plugs would just seat were the did before the the sleaves were put in.well the plugs hit the top of the piston and the sleaves came out all mangeled up with the plugs when I tryed to change them today. not sure what Im going to do. preaty upset
