Hi,

Noticed that my oil pressure was higher than what is was before. Just driving around town I noticed that I was running at about 80 Psi at 3000 rpm, before today it was around 65 Psl for those revolutions. Idle crept up as well, before 25 Psi when hot , now 45 Psi. I didn't change anything on the TR, oil level is where it should be. It got me a bit worried and puzzled. Any ideas anyone?

Thanks,

Yves

I'd suspect a gauge problem. See if your local garage can put a calibrated gauge in the side of the block to see what it reads.

The relief valve won't cause this problem as it is closed except to relieve high pressure.

It could be a sticky relief valve. Mine stuck open and I cured it with a new spring and clean. Details on this elsewhere on the forum.

A relief valve stuck open will only result in low oil pressure Keith, as John explained above. A valve stuck shut might give high pressure at high revs but will have no effect at idle.

Problem is also visible with different oil filters. Notable paper to felt. I noted a drop in Oil pressure with felt type filters. From MGC applications. Who knows the flow resistance of the current batch of paper filters ?
