The Ford tension specification for the relief valve spring (taken from the 120 CID industrial engine manual) is 44-46 ounces at a compressed length of 1.40 inches. oil cooler or oil pressure relief valve are performed. Section 1 Oil Pressure Relief Valve From start of production 1983, 944 cars came equipped with a spring and piston oil pressure relief valve (figure 1). This was used in all 944 and 944 Turbo up to the end of 1986 production. Also early 1987 924S used this system.The oil is also pumped up thru the cams, rockers etc and drains back down to the sump. The pressure relief valve in the filter operates if the filter becomes blocked, else the engine would be starved of oil. I do not know of any other valves for oil pressure, I suspect what you found was a one way anti-drain valve.An engine that has been running well but suddenly loses 20 to 30 pounds of oil pressure is likely suffering from debris in the oil pressure relief valve. A large piece of debris may cause oil pressure to drop to zero at idle. This needs to be fixed quickly, but it is not a difficult or expensive repair in most cases.One type is both manually engaged and manually disengaged. First, the valve is manually moved to an operating position. Then, the actuating mechanism reaches the end of its operating cycle, and the pump output continues until the system relief valve relieves the pressure. The relief valve unseats and allows the fluid to flow back to the reservoir.Aiming at the problem of the lack of a cooperation mechanism of combined relief valves, this paper proposes a new pressure-regulating and pressure-limiting combined relief valve. Combined with the ordinary relief valve dynamic characteristic analysis method, the dynamic model of the combined relief valve under normal working conditions was established, and its dynamic characteristics were ...Ensure the correct oil pressure and the right amount of oil is available at every phase of engine operation.
