I suspect that I have a minor oil leak coming from around the oil pressure control valve. I plan to replace the o-rings on the flange and valve itself the next time I change the oil.

However, the workshop manual references a special socket being necessary to remove the M36 nut that holds the valve in place once the flange is removed. As expected the tool costs a fortune.

Has anyone removed one of these in the past and if so, was a special tool actually needed or would a regular long socket do the trick?

I have attached a photo showing the flange should that help ring any bells.

Thanks.

First off then can i just humbly say that unless there is oil leaking outside of the picture that i can't see then what's shown is not a leak worth fixing .

The special tool is just going to be a thin walled 36mm double depth socket .. however it might be a bit longer than standard .. and this type of socket needs to be hollow inside .. i have a few like this for sensor removal but not this size .

I had a quick look on ebay and you can get something similar for about £10 .. i can't say if it will do the job or not but it's not a huge amount of money if you want to take a chance .

There is a special grease you put on the rubber O rings if you are doing the job .

Thanks for replying. I have attached a photo to give an idea of the extent of the "leak". I would describe as an oil mist rather than leak and it left only a 10p sized smudge on the driveway so I am not too worried. The photo was taken AFTER wiping the sump. I am trying to get an idea of the cost of replacing the o-rings vs just living with it.

Many thanks.

Taking on board comments from deMort and after car standing for a couple of weeks (been away) I took a further look underneath. It seems I have jumped to an incorrect conclusion as a drop of oil has collected on a low point of the upper section of the oil pan. I cannot see evidence of oil higher up (though the car was not raised so access difficult) and now I am wondering if the leak might be from the gasket between upper oil pan and crank case. The car is parked on a slope with back of car lower than front.

Has anyone experienced a leak (albeit minor) from the oil pan or had a similar issue and might be able to provide any pointers to other areas that might result in these symptoms.

Aghhhh okies .. yup you have a leak .. it's not the oil valve though ..

Image below .. try taking that bolt out .. cleaning it with brake cleaner .. coat the thread in engine grade silicone and refit it .

Clean off the entire area .. again we use brake cleaner then run the car up and look for leaks .. Hopefully it's just this bolt .. if not .. hmm .. sump gasket which is silicone sealant basically ( engine grade ) .

sealant = loctite 5900 .

deMort - thanks very much for the advice/suggestion which I will try on the next non-rainy day. I have my fingers crossed as I really don't think I can deal with replacing sump gaskets on my driveway!
