Over the 14 years I had my 50 degree I4 digifant in my westy I
noticed that i would get lifter clacking on start up towards the end
of the oil change interval.

I can't explain, but it happened consistently.

I mostly used mahle or mann filters, can't recall the part numbers,
but it most often was the one spec'd for the diesel vanagon. Also
tried I4 gasser filters, and wb filters. I didn't notice any diff
except the diesel filter was bigger.

   I see the Mahle oil filter is what everyone says to use, but I

using Fram or whatever I can get easily.  I have always changed my

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.
