Have you checked Clark's? It has lots of great information about our cars. Look under the "O" and oil pressure relief valve. It's fairly easy to remove and replace, just somewhat messy.

Yeah I saw that article, but it mentioned the use of a special tool and did not give too much info on the 'How to' part.

Keep in mind that I'm no expert on this, but I have had the OPRV on my cars out several times. My understanding is that the "special tool" is only needed if you have loosened or replaced the oil cooler. If this is the case, and it doesn't sound like it, some have suggested using the old OPRV as the alignment tool.
Maybe someone else with more experience could substantiate this.

There are a lot of threads on the OPRV. If you haven't already, you might do a search and finds some more answers to your questions along with some pictures. I have some pictures on my home computer that I can send you if you would like. If so, why don't you pm me and we can take it from there.

You never mention why you want to R&R the valve? Are you having oil pressure problems?

no oil pressure problems, steady 2 bar at idle and 4.5 while driving. It was mentioned by in one fof the PO service receipts that the OPRV might need replacing because of a slight leak.

There is a crush washer around the OPRV that you can try to replace if you do have a leak there.

Like Hank said, you dont need to use the alignment tool, but at $250 for a new OPRV i would just to use the alignment tool just incase!

But seriously, if you did not loosen or take off the bolts for the oil cooler i wouldnt worry about using the OPRV. To change the the valve, its pretty simple.. only requires a fairly large wrench or socket, i think 24mm?? I cant remember. Just be prepared for the oil to come out.
