Aircooled VW South Africa

Good day to all

What would the symptom of a weak oil pressure control valve be? I know what happens when the pressure relief valve sticks open, but am not familiar enough with the oiling system to know how a weak pressure control spring (the shorter of the two in a dual-relief case) impacts the oiling system.

If the spring do not keep it tight to pressure
You will have lower oil pressure

And if it dont open will it blow the cooler?

Yes if it do not open you will have excessive oil pressure that could pop the oil cooler seals etc.
