Oil pressure rising when accelerating!
Discussion
Just to update, had the oil changed and the new oil pump fitted and if anything there may even be slightly more movement than before. Monkfish have put this down to what may just be a tight engine. So, if you have this 'concern', I wouldn't worry. Unless my new pump has a faulty pressure release valve too! 
Ooooh paranoia, who needs it?!! I'm off for a thrash! By the way, Monkfish only ended up charging me for the pump and not the labour as a compromise, I was having a crank pulley changed which helped matters. Hope that helps!

Hello all,
Not sure if I've just not noticed this before but, yesterday, when I accelerated to around 5,500 revs, I noticed the oil pressure gauge rose to around 5. At idle or 'normal' revs, it returns to a healthy 3.
Is this a sign of a problem to come?
If I blip the throttle I notice an associated slight small rise in the pressure.
Be gentle with me if it's not good news,
Best regards
Ian
How warm was the engine? How hard was the acceleration?Not sure if I've just not noticed this before but, yesterday, when I accelerated to around 5,500 revs, I noticed the oil pressure gauge rose to around 5. At idle or 'normal' revs, it returns to a healthy 3.

Unfortunately, since I posted this, I discovered that I was getting oil leaks when I put the engine under any stress.
Turned out I had 2 failed pistons - (that were causing bottom end pressure).
Not saying that this high pressure was an indicator and don't want to frighten anyone. The 2 may have been unconnected. This thread was started way before I had the oil leak problems.
Did struggle for a while to identify the issue as the car was running fine under normal conditions.
Upshot was I had a complete engine rebuild ... but fully forged. Large hole in pocket but running great now and bomb proof!
And no high oil pressure.
If you want to know a bit of history as to how we discovered the problem and what the resolution was, MW Performance nursed the car back to life for me.
Hope this helps,
Ian
