    Hi can anyone help advise why I am having an oil leak that appear to be coming from the timing chain cover at the front side of the vehicle. Seems to be coming from above where the oil sump and the corner of the timing chain cover meet?

    I made sure a new gasket was used on the timing chain cover and RTV sealant was used on the oil
    sump. (I did all this work with the engine off so I could be thorough but clearly something is not quite right).

    Both mating surfaces were clean of old sealant and any other contaminants (brake cleaner used to remove any residue / contaminants).

    it’s not a massive leak but it’s enough to leave drips on the floor and go onto the undershield.

    You have not said what engine you have, so we all have to take a guess here....
    If it's the 1.4 TSI you can Exchange the gasket around the timing chain cover on the left side of the engine

    Hi it’s a BAG engine code 1.6 FSI.

    The gasket around the timing chain cover was new so can’t understand why it’s leaking??

    Where the rubber/metal gasket crosses the block to head face and the cam carrier to head face, you should apply a little dot of RTV to the gasket to counter any irregularities. Did you fit the sump after the chain cover?

    Yes I’m remember you telling me this and that’s exactly what I did. Timing chain cover on first then sump afterwards. Otherwise all the sealant gets pushed off into the sump and can block the pick up pipe / strainer.

    I made sure I applied sealant where the cylinder head and rocker cover meet and same for the block.

    Not sure why it’s leaking still though....shall try and upload a picture to show you if that will help?

    The sump requires a special very strong sealant, normal RTV isn't good enough.

    I used a product from Dirko Elring...

    ELRING DIRKO GASKET SEALANT 70ml VALVE COVERS / TIMING COVERS / SUMPS 036.163


    Is this not the correct type of sealant for the sump?

    I’ve got a previous email from you mentioning:

    D 176 501 A1 used to come as Loctite SI 5970 but not comes in a VAG branded tube whereas D 176 600 M1 is an odd grey paste I have not seen a brand name version of.

    I am having trouble with my copy of ETKA at the moment so I can't look up the details in depth but my other trade parts system states that "D 176 501 A1 silicon sealant only for position 8" which is the chain cover gasket and the sump sealant as D 176 600 M1 which is Elring 036.164

    Thank you. So 036.163 dirko product appears to be one number out (164)....

    Is there that much of a difference between these two products?


    still a bit confused as to why I’ve got this leak.

    looks like I’m going to have to strip it down again and get the timing chain cover and sump off to see what is going on.

    Let me know if your ETKA is back up and running @Crasher

    Can’t see any other reason why it is leaking other than maybe when installed sump
    i pushed some of the sealant off?

    Thanks
