Most 235's I have seen in good shape have 30-35 max when warm and half that at idle.
If it is going much above that when warm I would suspect the relief valve in the pump is hanging up.
Dave, my new rebuild(still running break in oil) keeps my gauge pegged at 30. When I can afford it I want to go to the Jim Carter rebuilt gauge cluster with the increased oil pressure gauge and the higher temp gauge but for now should I be concerned about the higher pressure?
