I replace the OPRV and am still having oil pressure issues. When warm the oil just falls off once it reaches 4bar. Here's the part that breaks my heart. I have at least $6000 worth of receipts in the last year. If I am to sell it, what can I honestly hope for in value? It's an 86 951 w/ turbo cup suspension. The only engine mods are a Vitesse chip, tial 38mm, and mbc. The engine likely needs a rebuild. The chassis is good other than the roof, which could use paint. The interior is a solid 8 or 9. I am house hunting and don't know if I can justify the $5k+ it's going to take to make this thing right. I need a drink.

what do you mean falls off when warm at 4 bar. When my car is warm it idles at 3.5- you mean 4 is the max pressure you can see when warm? What weight oil?

No ugly noises that I can here. I am using 10w/40 synthetic. The oil pressure, when the car warms up, builds to 4bar and then just drops suddenly. 4bar is about the max I see when warm. I also had some variation in pressure, but that was resolved with the new OPRV. I have approximately 160,000 miles now.

When changing the OPRV did you also check / clean/ replace your oil thermostat?

FWIW my gauge was continually giving me strange readings. I installed a mechanical gauge to verify what was really going on and found all the issues were electrical either in gauge cluster or with the sender.

99% of the time my oil pressure "maxes" out around 4bar when warm. (usually within a needle width of 4) ~5K rpm, which is apparently within factory spec. I was worried too, all of my previous 944s ran @ 5bar oil pressure anything above 3K rpm, but the FSM says its OK....
