I just bought a 1988 3.2 at the weekend and it's my first Porsche. On the second day of ownership the oil pressure gauge has started to play up by first twitching between min and max very quickly and then staying at the top of the scale the entire time that the engine is running. Is there any way of testing the sender unit so that I can determine whether it is this that is faulty or the gauge.
