I think, after many months, I have found the source of my oil leak. It appears to be coming from the mechanism (listed as the oil filter head on the online ETK) the oil filter and oil cooler pipes go into that's mounted on the drivers side of the engine. Looking from below there's a cylindrical shaped piece that seems to have a circlip of some description inside it and some form of cross marking and this is where the leak is coming from. No pics as yet to help identification but if this rings any bells is it easy to sort out?

Cheers

Steve

There is an O ring behind the cap under the circlip, which will have become hard and brittle with age and heat.
The new O ring comes as part of a kit for less than Ԛ£5 IIRC, and includes the cap and circlip.
Very common oil leak (amongst the dozens of other very common oil leaks on the M20), and easy to fix. Watch out for a part behind the cap that may fall out when you remove the cap.

Cheers Brian, once again you've come to the rescue! Time to phone the stealers methinks...................

PS How simple a job is this? Does it involve draining the oil at all?

Simple job. No need to drain oil. Only tools needed are circlip pliers and a smallish screwdriver for levering etc.
