High oil pressure

But sometimes after driving say 150km's the idle will drop further than it usually does, and then the meter easily drops 1mm under the lower line. I really hate it when that happens, but I have an old engine (200.000km's) so I decided to live with it. Maybe it needs a new oil pump..who knows.

I had the same problem with my aw11,it has 215.000 kilometers on it.I usually gave some gas when it was idling to raise the pressure (1100 rpm).

I was using 10w40 kroon oil back then and I am now using 20w50 oil.The problem is now solved.I think the engine is simply showing some wear,Not strange for a 4age with a lot of kilometers,You never know how previous owners drove it, probably hard.

Maybe it are the main bearing or indeed an oil pump.
