Hi,

I need to reset the oil pressure bypass valve on the 2 L spider. Has anybody got any guidelines as to approximately what a quarter turn or a half turn of the screw would make in terms of adjustments for the pressure. If I can find out what a half turn for full turn difference makes it will just speed up the process for me.

If you would measure the spring rate of the spring and you know the pitch from the tread of the adjuster than it's no rocket science to calculate.
But plugging in a manual gauge sounds more accurate to me.
