I race my Sapph with similar pressure. It sits at 20 on idle, rises to 55-60 as I rev it and holds 55-60 during use. On idle it steadily falls back to 20ish. It was at Grove Garage recently and they didn't comment. As far as I'm concerned that's normal.

yeah my oil pressure is 50 PSI on tickover when cold on Mobile 1, drops to just below 20 when warm though, need a better warm idle pressure so it may help then..

mine was never that low on idle, unless i had given it a serious serious thrash, and then would be around 25.
Also my cold pressure was more like 60-65
paul, yeah the tappets were silent before, might jsut be a shitty tappet but there were brand new.

Sorry to drag this up.
Mines usually 60 ish at cold start and 50ish when warm and driving gently, rising to 55-60 when revving, and 35 on idle.
Tonight gave it a bit of beans and it dropped to 30 when idling but then climbed back to 35 as usual.
I take it this is normal, it was just a bit warm??

ford spec with 10w 50 is 1.8 bar at idle at 80c oil temp. you could try a 10w 60 that should give better hot pressure. i dont thnik youve got anything to worry about though at 20 psi.

my dropping oil pressure turned out to be a screwed engine!! but i was also loseing pressue when reving not just on idle. looked at the back of my rocker and the powdercoat has been burning off and blistering due to head heat so not much cooling going on!!
