[Vwdiesel] Nicks Pressure drop

[Mark Shepherd]

 Since you have 70psi at the filter and a max of
20 at the head then you
have a restriction (that's not supposed to be
there) somewhere in between.
The big problem with that is that you don't know
where that restriction is.
The filter itself, just inside thus restricting
oil to the bearings as well?
In
the head, the passage to the head, simply ahead of
the oil sender port?
Although it seem like sort of a non problem, I had
a simlilar situation
with a baja bug I had.  It took out the crank
because the pressure port
wasn't the only thing with no pressure.  :(

This reminds me of a possibility that a crank
bearing could be drinking all the oil when warm.
My second Quantum had the crank bearing behind the
pulley badly damaged (from running dry?) by a
previous owner ;o(  Head pressure would drop when
hotI didnt believe the warning buzzer cam dried
out and siezed on two bearings and snapped the cam
belt (1.8gasser).... Sump off found problem; the
cam I freed with fine carborundum paste.
It ran perfectly until it died of rust and the
holes where rust used to be...
