A mechanic heard the noise & said this -->
Sounds like the shaft that the rocker arm/lifters ride on is turned and broke off the dowel that holds the shaft. This in turn makes it so the oil feeds to the lifter/tappet are blocked and that gives you the tap. The tapping is of course your lifter/tapppet starving for oil.This is unfortunately common on the 3.5L
have the same problem?
