No idea what it is made of. I think Viton O rings are brown? This one is black and so was the old one.
I told the guy what it was for and he measured the cap and went and got it. Had a bit of a chat about Rover V8s and off I went.
I would assume that it is the original one and at 15 years old it has only been leaking for the last one. So I'd say she'll be right for a little while.
One thing I found while looking up the oil pump online was that this O ring is susceptible to leaking after an overheat. I did overheat it just before it started leaking. I changed the heater hoses and didn't tighten up one enough and it leaked. The oil leak began very soon after that little mistake.

If you find it and it's not the pressure switch let us know I have a leak behind the oil filter That I can not locateOriginally Posted by BigJon

Didn't find the leak while under the car, now I will grab my torch and look from above.

If it is leaking from there I think it will be hard to tell without degreasing the engine in that area. The oil on mine was blown over pretty much the entire driver's side of the block and that general area. It was easy to spot once it was clean though.
You will be kicking yourself for not doing it before you installed the 3.9 though
Mine was running down the underneath of the oil filter then dripping on the ground and the diff housing. Sounds like yours. May be the O rings on the oil cooler pipes too. I changed mine a while ago.

I am getting new cooler pipes made up at the moment.
When I fit them I will pull the alternator and A/C compressor off. It is an easy job (just did it on my wrecker Disco) especially as I don't have the A/C pipes hooked up yet.
Then I can replace the O ring with relative ease.

You will have better access but the main issue I found is trying to push the cap in. It is very close to the steering box so you have to come at it from either side (I found the front the easiest).
Makes pushing it in straight a PITA.

I should clarify that I found coming in from the front the easiest. I came in from underneath at the front.
You might be able to do it from above if you totally remove the aircon compressor since it isn't connected. I unbolted mine but it was still plumbed up so could only move it small amounts.

I will pull the bracket right off the front of the head. The Disco in the shed has the intake manifold and alternator / A/C bracket off at the moment. So much room in the engine bay now!
Look at this room...

By comparison, this is the Rangie engine bay after fitting new cooler hoses and o ring.
I slightly modified (grinder) a pair of small pointy nose pliers to access the circlip. I don't have any right angle circlip pliers.
