    Hello all - my first post.

    Noticed oil leak on my C240 coming from between oil filter housing and component with fins on it connected to the filter housing.

    There is a slight seep of oil from this which is dripping onto the drive belt and splattering all over the engine bay.

    Any ideas what is causing this and what has to be replaced?

    Any help much appreciated and is this a DIY job or is specialist needed?

    Cheers

    Also interested I have a similar very minor leak in that area - need to have a closer look with torch and mirror.

    N.B The finned thing is the oil cooler.

    P.S. Welcome

    This might help - seem to be several gaskets that could be responsible.

    The seals go hard over time and leak, this happened on my father-in-law's car. The 2 seals in the lonk cost about £25!, not a difficult diy job, just don't overtighten the bolts on reassembly.

    Do this as soon as you can as in my case the drive belt came off whilst driving.

    Guys,

    Had it fixed today and Osbornes only needed to replace the oil filter seal at £1.80 plus labour.

    All okay now - thanks for your advice

    Cheers

    Simple gasket paper seals like these can be made by an indie (time served) with a trick of the trade) tapping a gasket ! Time served will know what I am talking about ??

    Just replaced the two rubber seals on the oil cooler as they seemed to be the culpit on mine - was going to do the cheaper one on the bottom on the filter housing but didn't have a big enough socket (only have up to 1.5 inch need more like 2 for that!!).

    Old seals were very dry and brittle - large one broke into peices on removal.

    Syphoned out the power steering reservior and filled back up with new fuild while I was there, old stuff looks very dirty (128K on the clock now).

    Was working outside in the snow/ice on the drive - felt suprisingly warm in the sun.

    With reference to post #5, my father in law improvised for a couple of weeks by using blue hylomar on the seals, worked perfectly. We replaced the seals eventually just to be sure.
