Found out why my '87 was making a horrendous banging sound: the rocker
arm for cylinder 2's exhaust valve broke at the screw hole. Removing the
rocker arm assembly was impossible, as the broken arm's jagged end
caught on the valve guide/spring. As gentle persuasion didn't loosen the
arm, I resorted to tapping the pushrod end. This finally loosened the
arm, and subsequently the valve springs went poioioioing out of the
head. The valve guide is also sticking out of the head.

After peering thru the Bentley book, in addition to trying to glean
clues from the Haynes and Chilton aircooled books (OK OK, but at least
they have procedures in them), it's looking more and more like I'll have
to pull the right-side head. SO, I have some questions:

1. Do I REALLY have to pull the head to put the valve crap back
together?

2. To pull the right head, what do I need to disconnect besides the air
filter assembly, exhaust manifolds, pushrod covers, coolant hoses, and
fuel rails?

3. Do I need VW tool #**@#$%&!~& ?

Once again, thanks!
