I don't NEED anything related to this car, but it would be nice to have two functioning gauges that don't leak all over the place.

The oil pressure would be nice just to know when the engine is warm and it saved my ass one time when I didn't tighten the oil pickup and almost blew the motor due to very low oil pressure.

The oil temperature would also tell me how warm the engine is and it would give me a good idea of how long to let the car idle to cool down the center bearings of the turbo.

Either one seems pretty useful and they are very cheap too, I just want to know what you guys think would be the better option to replace my defunct mechanical oil pressure gauge.
