1991 S2 Oil pressure problem
Hi everyone,
Driving cool on the highway, the oil pressure suddenly dropped to the red area, and a curious noise coming from the top of the engine happened.
We stopped the car and towed it to our house. After many investigations on the Internet, I spotted the OPRV to be guilty. I removed it today and tested it (without dismantling it) : the piston goes smooth and free within its sleeve. Could it be faulty despite its good looking appearance or should I investgate somewhere else ? After I put back the OPRV, the oil pressure level was about 2 at cold engine startup, with the noise still being here (you can clearly hear it in the video).
Many thanks for any help :-)
