According to my man, the pressure relief valve looks OK, and after cleaning the valve and oil change – including filter, there is no change.

OK, so if anyone's interested the OPRV has been replaced with a new unit.

There are numerous threads but they seem to run off to the type of oil, the ambient temperature or the sender, but what I need to know is what’s normal – is there such a thing?

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.
1 acknowledgements have no verified action link; they do not establish a repair result.

According to my man, the pressure relief valve looks OK, and after cleaning the valve and oil change – including filter, there is no change.
Hello,
I am new to Pistonheads and I have recently acquired a Gen1 997 CS2. It drives like an absolute peach. 47k miles, full service history – mostly by Porsche dealers. I am new to Porsche and I love it.
The issue I have is the oil pressure. I know it’s high when cold, is affected by the viscosity and all that jazz, but I need to understand what is normal and what I should be concerned about.
At normal temp, the car idles at around 2.5 bar. At anything over 3k revs it goes off the scale. I have taken it a specialist who has confirmed it runs at 6 bar at the higher rev range (using their own instruments). I know what the manual says and that is way lower than my own experience.
According to my man, the pressure relief valve looks OK, and after cleaning the valve and oil change – including filter, there is no change. The next step is to replace the valve – due tomorrow.
There are numerous threads but they seem to run off to the type of oil, the ambient temperature or the sender, but what I need to know is what’s normal – is there such a thing?
Could this high (in my mind) pressure be masking something more sinister.
Am I paranoid?
Thanks

HI, I have the same car with similar miles. MY05. The pressure runs about 5.5 when flat out and drops I guess to about 3 when warm and idling.
She is on Mobil 1.
All my cars have I believe been about the same and I think is normal.
Hi, thanks for that.
The more I look into this, the more it appears that my car is "normal" - whatever that means!
I would have thought that it would be more widely known and perhaps Porsche would have done something about it!
Cheers!
OK, so if anyone's interested the OPRV has been replaced with a new unit.
The gauge used by the workshop folks at Auto2000 now reads just over 5 bar when cold, around 2 when hot, rising to around 5 under acceleration. Previously this had gone to around 7.
The valve was the culprit.
Happy days.
I can now look forward to getting my mitts on it at the weekend.
