Mike/List,

This is a load of hokum that has been going 'round the list
for a while.  The only valve in any oil filter is a bypass valve
which would activate itself if the filter media got too clogged to
pass enough oil, for instance.

Let's see: How would a valve that kept the lifters from bleeding
down work?  It would apply oil pressure.  Where does oil pressure
come from?  The oil pump.  When the engine's off, the pump's off.
So when the engine's off, there's no oil pressure, regardless of
how many valves you have in your filter.

PS - speaking of hokum, (and I'm not trying to be aggressive - just
asking the question) how is it that replacing just one of the two
pneumatic rear hatch struts can cause it to fail prematurely?  One
strut doesn't know what the other is doing.  It's just applying
pressure to a piston, right?

But what about the valve in the filter that keeps the lifters from
leaking down?
