Thank you! My values are far away of those. So not sure what to believe. 5 bars at idle, hmm. Very good lubrication or very bad for some sealing.

Re: Ep6 5fs 5fw help
Hi. Sorry for jumping in so late. I believe your issue is that you engine has the new variable pressure pump. More accurate to say the solenoid controlled constant pressure pump. The old pump without the solenoid is technically variable pressure since it's directly proportional to the engine RPM.
The solenoid pump is much bigger and at the same rpm and without pressure being mitigated by the solenoid, will give off much higher pressure. The higher pressure would also mess with the Vanos dephasers, as they use pressure to operate.
I'm about to do what someone did with your car to a Citroen C5. It has a seized engine, they took it apart and left it. I'm thinking of buying the car but I can't tow it, and I have a rebuilt EP6DT engine. The C5 has an EP6CDT. All the ancillaries and accessories will fit, but my block just doesn't have the port hole for the solenoid cable. I'm thinking maybe use a regular pump and connect the valve just to fool the ECU. OR leave the solenoid connector unplugged, it would probably throw a code however. Or make a hole? But that seems barbaric. Maybe use the engine just to drive the car home and rebuild the original engine as I'm going to anyway.? But then that's an extra engine swap. Does anyone have any advise? It's a very good car with hydro suspension too trim. They said they were thinking of scrapping it. I want to save it.
