Oilpressure - Mf135

[assy]

My 135 runs with a bit high oilpressure (I think?). I've changed both the oilpressure-pipes and the gauge, so I dont think it's showing me the wrong pressure.

Any comments on if this is to high when running under normal conditions with abit load? And if so, what could be the cause of it?
(it's a 1970modell, running 2760hours. Fresh new oil&filter, with no signs of water or any other contamination in it)

Have you checked the engine breather pipe? They are renowned for blocking up causing back pressure.

No, not checked that one. Where is it located?

It it the one one the right (marked in red) in this picture? If so, the hose was recently changed, and I think I cleaned the pipe aswell when I changed the head gasked a couple of months ago...

Yes that’s the one. I had one block up a few years back.

What engine oil are you using? The wrong oil can increase pressure

I wouldn’t be too worried about it, come to think of it if it’s worrying you I’m sure I could swap some of my lack of oil pressure from mine.........

I use this on both the engine, and the hydraulic/gear :

I just have in mind from last year when my head gasket broke (and the preasure when skyhigh), and got lots of coolingwater in the engineoil
