Well, not sure what I could check from oitside beside the pressure above idle what looks fine as soon the revs increasing. The engine was new build and got around 500KM max.. sorry no oiltemp installed, thats the next job.
Rereading what David stated it could be at the edge but still within what has been experient?

Cheers Volker

There can be big variations on Duratec's but for a healthy engine (when hot) idle should be 20-30 PSI (~1.5-2.0 bar). That should increase to 60-90 PSI (~4-6 bar) at max RPM. There's a very tight bearing tolerance on factory engines and this is often not preserved on some performance builds, so some engines may show (disturbingly) low pressures. But this not necessarily a problem provided it is in good condition and stable.

Anyone please?

If it is a rebuilt engine that had new main bearings then the oil pressure may get low at idle. I would suggest you try a 10W60 and see how you get on. But be careful with the warm up as the thicker 10w60 needs a little more temperature (longer warm up) to reach it's safe operating viscosity.
