Ok. Has the timing belt ever been changed?
I ask because if the belt IS worn out you could be hearing a valve tapping on the top of a piston. If this is the case, one more tooth out and your entire head will need to be reworked. See, timing is very critical in these types of motors. As the timing belt stretches it begins to hop or skip making the timing become more and more out of synch. The last straw is when the piston is at the top of the stroke and the valve(s) are completely open which causes total havoc.
I will make a call right now to a buddy and ask what a common problem is with those motors and report back.
