Hi Folks
Had been hoping to save my 924th post for something really special but here I am.
On my last drive in my favourite car I noticed the initial oil pressure on start up and until the oil got warm was an incredible 10 bar (on the guage). As usual I took it fairly easy initially, and noticed the oil pressure came down to around 4-5 bar; however even at idle the pressure remained at 4 bar...which it never does, usually dropping to around 2 bar.
Now first thoughts were that the guage was faulty, but on return home when I parked up, there was a strong smell of oil, and sure enough, on popping the bonnet, there was oil seepage from all sorts of seals/gaskets and joins. So something certainly is amiss.
My thoughts are to pull the oil pump relief valve.

Recently I believe this was discussed, but I can't seem to find the thread, although I recall 924RACR was involved. I tried to PM Vaughn, but my PMs aren't going anywhere for some reason.

For the record: the motor is recently rebuilt/the oil is correct grade synthetic Mobil1/and no, I haven't checked the pressure with a manual guage....I couldn't get my fat hands down the back of the head.

Any thoughts, Guys?

Yeah, seems hard to imagine that'd be anything other than the OPRV... remove and clean!

That happened to me one winter when i had thick summer oil in the car, i could see oil coming out even from the camshaft seal at the front of the engine.
Could be thick oil, could be the valve, or a combination of the two...car having sat for a while, thick and old oil.
