I always run Bosch oil filters which is the OEM supplier for VW in North
America.  I never have a oil pressure problem.  There could be a few other
reasons for the oil pressure 'problem' you are having.  First the earlier
Vanagons have only 1 oil pressure switch, a 0.3 BAR switch, your Cabriolet
motor has two switches, a 0.3 BAR and a 1.8BAR, if you oil pressure light is
looking for 0.3 BAR and it is connected to the 1.8 BAR sender it could take
a while for the oil to reach that pressure.  In my Golf TD it take about 10
seconds for 2 BAR to happen - more if it is cold out side.

I had the same problem with mine, though it was an earlier
motor I swapped it for, I solved it with a better filter that
has an anti-drainback valve.  I've heard of folks just using
the larger diesel filter..

My two cents is the "Pure One filter" from Purolator
http://www.pureoil.com/  seems to do the job.

Subject: oil pressure at startup in diesel swapped inline 4

I have a diesel Westy that was swapped with a 92 cabriolet egnine.  The oil
pump and pan are the original from the diesel with a total of 50k miles.
50% of the time at startup it takes about 1 minute for the oil pressure
light to extinguish.  The other half of the time, it goes out within
seconds.  Is there a oil pressure checkvalve somewhere that loses the oil or
prime.
TIA
