The problem with filters is that most don't have suficient internal
spring pressure to maintain the oil in the galleries of the engine when
it is shut down. This often results in the "clattering lifter" syndrome
that plagues the WBX engine. Over time, I suspect that the draining of
oil out of the galleries and the consequential wear occuring on startup
while the galleries and spaces are being refilled with oil eventually
results in problems in the engine. It is a slow cumalative process but
will eventually bite you on the butt!! The black colored Mann/Mahl oil
filters seem to be the only ones that meet the spec and do a really good
job. Anything else is junk so far as the WBX engine is concerned.
