Might be a bit hard to answer this one - cos the stock oil pressure gauges aren't really calibrated... But I saw on another thread talking about knackered oil pumps and noisy hydraulic-ing at idle. Well, when the engine is idling, I'd say the pressure is in the bottom quarter of the gauge with Mobil 1 oil, but about midway when the engine is over about 2000rpm. It sounds healthy enough, doesn't really have heavy oil consumption (despite having 125,000miles). Is there any way to tweak up the oil pressure relief valve on these pumps?

 

Thanks for any advice. PS Anyone want any stock wheels?

To be honest I wouldn't worry about it too much. The gauge (or rather sender) is so inaccurate that you don't really know where you are. And I have never personally heard of an oil pump failure.

You don't say which grade of Mobil-1 you're using, but I would avoid the stuff that is really thin.

Mines does the same once its warm, before that it slowly descends from the 3/4 mark as the car warms up.

Thanks guys, I'll stop worrying then... Yep when I do an oil change I'll put the thicker grade of Mobil 1 in. I remember the first time I came across 0 weight engine oil... NEO oil, at £45 a gallon! (Ten years ago...) I ran it in a Formula Ford race car, and at the end of the race you'd have about 7psi on the gauge at 7000rpm... It was supposed to give about an extra 2BHP on the dyno:eek:

Isnt it meant to be 30psi at idle or something? And 60psi at 3000rpm?

 

Its amazing how much the oil pressure goes up and down with the revs. My after market dial is changing constently while the stock one usually goes to about 60psi then plumit to 0.
