[Vwdiesel] Is it weird oil pressure?

[Mark Shepherd]

Maybe head oil pressure simply related to(inversely
proportional to) turbo rpm which is itself directly related
to load/ engine speed up to it's maximum output. Then
greater vehicle speeds just increase oil output from pump to
everywhere else

Y=x-0.1x (upto a maximum turbo created boost pressure)
Then
Y= x-k

Where Y is oil pressure to head and x is oil pump output and
0.1x is a notional 10% reroute to the turbo.

This is mathematical 'ollucks with several missing variables
but I think the idea is correct...
I'll try it out tomorrow(gauge wise)
