If you are using a
steam gauge for the coolant system pressure gauge here are 2 suggestions (this
was my experience with the Ford V6):
1)
You need
some negative reading on the scale, i.e. the coolant system becomes a vacuum
when the engine cools down … anything in your overflow gets sucked back into
the engine.
2)
Don’t
put the measuring point in the engine block; you will get excessive pressure
readings that will scare you. Best place is on the inlet to the water pump,
Tee-in a swirl pot or equivalent and leave an air
gap.

Thanks Jeff for the advice.
Will see how it can be implimented.
