[Vwdiesel] What to look for to find a hydraulic lifter tap

[James Hansen]

Probably a little late, but the noisy ones have too much room between cam
and follower (lash).  Run the motor, shut it off, remove valve cover, use a
feeler gauge.  The noisy one will have significantly more lash.  It's always
worked for me...  BUT, for the cost, 8 cam followers are cheap, and if one
is shot, it probably has friends standing in line right behind it.
