Oil pressure rising when accelerating!
Discussion
Thank you Slippery/Liam for testing this out on yours.
I hope I haven't made you as paranoid as I am Slippery!
As you say, if we didn't have the gauge, we wouldn't have to worry - and there are no other signs of a problem.
Went to Daresbury this afternoon and, although not scientific, it looks like a slow increase to around 4500 revs has little effect on the pressure - I didn't get chance to take it to 5500 but it looks like the effects of doing that are similar on our vehicles. I guess I don't often take the car to that rev level and, perhaps, I just haven't noticed the gauge before when I have - too busy hanging on
.
That said, Liam's experience differs to ours - and I see you also have a VXR Liam (mine's a 2006 BTW).
Think I'll decide not to do anything for the moment though (can't afford it anyway) but I would really appreciate the feedback from Monkfish Slippery - thank you very much for offering.
Hope everything is OK - for both our sakes ...
Best regards
Ian

Obviously Liam's engine is sh@gged, and all of ours are okay. 
that is too a possability 
you'll be please to know araf, that the bm got a jet wash yesterday

Come on ARAF, test yours too!
My Ka doesn't have an oil gauge. As to my wife's VXR8, if you think I'm driving around for the next half an hour, just to see how high the pressure needle goes when I boot it - then think again. I've been drinking. :hic:
Not sure if anyone's still looking at this thread, tho I wish I never had, paranoid now!?
Mine's been off the road for the winter (booked in at fish on 26th ) but noticed the other day if I 'blipped' the throttle the needle would hop-up a bit. Temp gauge was at normal running temp, engine had been idling for about 10 - 15 mins.
I held the revs at various rpm's from 2k - 5k and the pressure rose the higher the revs were held!? Never did this when I last drove it, was always around 3bar apart from when it was v. hot when it dropped to around 2.75 - 3bar.
Is the oil pressure relief basically just a ball-valve controlled by a spring or is it more complex than this?

As a result of this thread, Monkfish are currently installing a new oil pump. I will report back on what has happened to the reading over the next few days. I could have left it, but with that mauch pressure there is a risk of popping a seal somewhere and it's one of those things that niggles once you're aware of it.
