Fw: [Vwdiesel] Hillbilly Tuning

[Gerry Wolfe]

A dumb question from someone who hasn't ever done a static timing (lacking
measuring tools & a place to do it)...

Does the timing belt cover need to be removed to do this procedure?  i.e.
are the "3 of 4 mounting bolts" accessable?

advTHANKSance, g.
