Just curious what oil pressure at idle should roughly be ? The engine is a mild 1275 webber and cam and done around 5000klms.....

Thanks

Preferably not zero :P

With my limited knowledge I would guess not < 25psi with oil in good condition and at normal operating temp. Obviously there are factors like viscosity and how hard the engine has been working, existence of oil cooler etc.

Depends a bit on oil viscosity and what the engine was built for, but at idle (~900 rpm) anything over 15 psi is OK.

Its moving around alot with engine revs, as expected but I didnt think it would move as it does...

yopu could take the relief valve out and have a look - might be some gunk in it, or badly scored

I actually replaced it and the spring I "thought" I had an oil pressure issue so replaced it as a matter of caution....

Idle around 20-30, then running at say 100 kph 80psi.... obviously depends on engine rpm.....
So it appears to be OK....

Sounds fine to me, perhaps a little on the high end when running though, leads to high oil temps.

Could be worth checking the filter at the back of the gauge on both cars. See my post...
