Hi I have a silvertop 1.8 zetec with 5/30 semi synth oil. The normal engine temperature when driving is 80 Deg C (sensor is in the thermosat housing) and oil pressure remains at about 80 psi.

Is this normal temp/pressure for the zetec? If not, do I need to do anything about it? I am wondering if the temperature is too low I could block of part of the radiator?

That sounds good there, nothing to worry about.

OK, thanks for the reply Coozer.
