Need a schematic drawing if poss to locate the oil pressure relief valve on a Ford Transit 1997 model - 2 litre engine. Have replaced the oil lift pump and the oil pressure light is still indicating NO PRESSURE. Told it's possible that the oil pressure relief valve is not working, therefore not sealing off to lift oil to the whole engine.

Are we talking about the DOHC 2 litre petrol? Also I'd start by checking the pressure switch rather then the relief valve.
