I see the Mahle oil filter is what everyone says to use, but I have been
using Fram or whatever I can get easily.  I have always changed my oil more
frequently than most.  Until I swapped motors, only if my motor sat for a
few days would my lifters click on start up....now they seem to click every
time for perhaps 10 seconds or so...not so good, I imagine.  Is the Mahle
filter supposed to help with this...some kinda drain-back valve in it or
something?

  For complete disclosure...I have an inline VW motor, gas.  Mounted as a
diesel at 50degrees.  I kept the same head, unchanged and undisturbed when I
recently changed over to an ABA block, which also has the newer style
oil/water interchange filter mounting.  Dunno if that changes anything.
