no for the bad part... Ive recently notice a tapping noise from the drivers side valve cover, per my neighbors request (check this out) we took a wooden dowl rod and placed it to the valve cover and to the ear and listened. Beleave it or not you could hear a differance, the passanger side all sounded the same, and the drivers side front 2 cylinders have a deeper sounding tapping noise, is this normal ?

The unwritten trouble-shooting matrix
If all are doing the same:
Could All be bad, or could all be good
If some are doing different:
Some are bad, some are good.
Seems like a clearance issue (pre-load). Does this sound go away as the
engine warms/cool?
