With the head gasket out of my 99 TFR it makes a sort of clunking noise. But I can also hear it kinda with the gasket. I'm positive nothing is hitting with gaket out. So it leads me to the conclusion that it is not tight enough, becasue the thread on the idside of the nuts that hold the head on is wearing away, and gone is completly gone on two of them (kinetics have soem quality problems). I think im going to buy new nuts for it today hopefully. Do u think that the clunking could be from the head not being on tight enough.
