Hi all you nice Vanagon experts,
I'm seeking your advice and comments. Periodically (often after the van
hasn't been used for awhile) I get a knocking sound from near the valve
cover on the driver's side. It gets louder when I increase the idle
speed. It gets softer and often goes away after the van has been driven
for a few minutes. The sound has been occuring more frequently over the
last 20,000 miles (out of 137,000 total). What are your thoughts?

Thanks to everyone in advance,
