When I'm at idle, there is a tapping noise. Sounds like a loose valve? Can I tighten the valves on this p/u by removing the valve covers? How do I silence the noise. I've tried Marvel magic oil, engine lifter stuff and nothing. Any answers would be appreciated.

Ok. I removed one valve cover today 6/4/09 and found no where to adjust.I used the handle part of a large screwdriver and placed pressure to the bottom arm and it seemed to reduce the noise. It has one bolt in the middle of the arm. I tried to tighten but it did no good. So I brought it back to the beginning
So how or what do I do to stop the noise. Sounds like a loose valve from my old car days, but louder.
