OK, I need some advice. I recently had some problems with the Trooper in respect to sucking water. I fixed the problem associated with that, but stupidly enough I pulled both the cams out of the head. Not the smartest move. Got the back in right and aligned up, but now it seems that I somehow messed up the clearances. The got the feeler gauges out and on the exhaust side they are way out of spec. From what I have read, there are shim on the top of the rocker arm that are different thinknesses. Anyone have any experience in adjusting these things? It only the exhasut cam that seems to be bad and noisy. Any suggestions? Thanks,
