There are a number of reasons that cause lifters to become air bound and
clatter. A sticking ball check due to wear or contamination. The usual fix
is to run the engine until the oil is warm and then run it at speed.
Sometimes 4,00 rpm plus may be needed. If you have a lifter or two that
regularly does this, probably the lifter is bad. Adjustment is not an
answer.

On the air cooled engines, single lifter replacements are easy due to the
removable pushrods. When the engine is clanking, shut it down. Remove the
valve covers, and setting the engine like you would for a valve adjustment,
the soft lifter is easily found. Just replace it.

Yah, that makes sense.

I haven't adjusted the valves (preloaded) yet. Since
it's likely air is present in lifter(s), I will do as
Bentley says and set valve adjuster screws to .006",
to see if that helps. If so, I will preload them. If
not, I will take out lifters on passenger side (I
could hear/feel noise there) and see who needs
cleaning/replacing.

And people, If any of logic/methods don't make sense
(the world of hydraulic lifters is new to me), please
advise!


Thanks!

Neil.
