When repairs are made to the oil cooler or for oil pressure related problems, new oil pressure relief valve (Arrow A) Part Number 944 107 035 11 should be installed. This part will retrofit into all 944 engines from beginning of production 1983 through '86 models. It is important that the sleeve (Arrow B) be firmly installed in the crankcase. In addition, the oil cooler housing must be properly centered. Check with special tool P-9215 Part Number 000 721 921 50 and adjust if necessary.
Note:
Some 924S (early production cars) will have the former version piston and spring installed. When repairing them, the above mentioned valve should also be used.
