    Hi,

    Where is the leak in the oil filter housing?

    If it is leaking between the screw top and the housing, you will need to unscrew it.
    To do that you will need an oil filter housing socket. I have one but I am not near it at present so I don't know what size fits your car.

    When you have it off you need to fit the rubber O rings in the correct place or else the oil will seep along the threads on the filter cap and leak.

    Was the oil changed recently?

    Thanks for the reply it’s actually leaking from the bottom where it meets the engine but seems a bit tight to get a socket in without removing the a/c pump

    Official procedure is to remove Power Steering Pump & AC Compressor with lines connected and place to one side.

    Yes. first thing to do is remove the serpentine belt, well after you remove the engine cover and plastic cover at the front of the belts.

    Do you need to lock off the pulleys

    Hi Pat, do you have a similar diagram and instruction's for removing the fuel filter housing? My E class is leaking a minute amount of water, but with no visible sign's of a leak, so I think that the fuel filter housing is the culprit.
    Thank's, J.

    Epic does not do it Justice Pat. Should be more like Cecil B De Mille's "The Ten Commandant's " in Glorious Eastman Color, with a cast of Thousand's..( slight exaggeration I know :D:D:D )
    My one is a 2010 E Class W212, OM651 2.1 CDI engine. ,

    On my OM651 leak thread, don't assume it's the Filter Housing. ;)

    Thank's Pat......No I won't. Not after following your "adventure's" with Leak's anyway.....I've added the leak finder, and examined it underneath, on top, the front etc with the ultra violet light...no luck. Its a bit hard to see in and around the fuel filter housing, especially near the block, where I'd imagine the leak is. If I'm going to open it up all round the filter just too inspect it, may as well get the part and fit it. One possible cause ( or solved?? ) eliminated..
