Re: 156 Oil Pump/Pressure Specs....?
I have no experience with V6, but I have an oil pressure gauge on my TS. After a cold start the pressure holds on 4,5 bar at idle and rises to 5 - 5,5 bar when driving. As the oil warms up the idle pressure drops. When oil temp is anywhere above 70 degrees, the idle pressure is 1,5 - 2 bars. When driving, it rises with the revs and somewhere above 2500 - 3000 rpm it reaches 4,5 - 5 bar and than it is stable up to the rev limiter.
I think the pressure relief valve opens disregarding the oil temperature and engine revs anytime when the pressure is above 5 bar. It may be opened slightly even at idle after a cold start when the oil is thick and pressure is build up rapidly but when the engine is hot it can start to open later, when the pressure rises above a pre-set value (5 bar aprox.)
