Yes but if im taking some more HPs than stock TD I would like to have
all the oil that is being pumped going through my engine. Or is it
just too insignificant to make a difference? Thats only reason why I
thought not to do it like You suggested.

It is mazda 1.7 PN diesel engine in an old mazda 323 1987 model (body
that is, the engine might not be -87). I still have it, although hasnt
been driven for 2 years now. The engine would run just nice, not so
with the rest of the car. It is very rare I have not another one of
these engines in mazda in Finland ever. And we have had lots of these
mazdas here. 2. best diesel engine I have ever seen.
Now that this discussion is started I began to feel interrested about
this. I can go and check those filters next time Ill go to continue my
VW project. I am not 100% sure about the function of the second
filter, but I know for sure that there are two. I can take pictures
for You ;)
Obligatory vanagon content: I am under impression that the engine
itself is quite a like the VW 1.6 NA prechamber engines. This engine
is not based on any previous mazda diesel. Prechambers are quite
similar along with positioning of the glowplugs. I still have not
bought my first VW diesel, so I cant yet really tell more exactly.
