    Hey guys, so long story kind of short the water pump bearing failed and resulted in cutting into the timing chain casing. Now it was repaired temporarily with quiksteel but only lasted a few months. So i decided to take the pump off and try doing it again, only this time the whole piece of alluminium fell off and left a big hole!
    So, i fished the missing piece out of the engine and i wanted to go about getting the hole welded over, however nobody wants to touch it as it is.
    My choices now are to either try something stronger than quiksteel and put a piece of alluminium over the hole but i would prefer to have it done properly so my next choice is to remove the timing chain casing and go and get it welded...
    So the question is, what is involved in removing the timing chain casing? I already have the rocker cover removed

    Any help much appreciated as a i am now at my witts end and cant decide what to do.

    Don't bother trying to weld it as the quality of the metal is crap, get yourself another timing case from a breaker.

    That may be an option if i find another or what other models will be the same.
    Then i need to know how to remove it.

    Yeh spttoed that buddy but not 100% if it will be same? I assume it is though. Biggest problem atm is knowing how much work is involved to see if its worth it or not

    The timing case is the same so you can use that, but the 230k engine has internal differences to yours.

    Most similar aged M111 engines should have the same timing case cover:

    C180/C200/C230K

    Your definitely better off replacing it if your going through the hassle of removing it to possibly weld which would never be as strong

    I cant remember now haha. I havent actually doubled checked the number on mine because i need to take the crank pulley off 2moro to see it. But i found 1 on the internet that is identical to mine and came from the same engine so i gave the guy on the phone the part number from that 1 and he said he has 1 from a m111 but its a different number. This is a mercedes specialist place and reckons it should be the same but i would like to know if anyone else could give an opinion before i take mine off and go compare them.
    The 1 i got from google that says its from the same engine as mine is R111 015 08 01
    The mercedes guy has 1 with a different number.

    I cant think of any physical differences between m111 timing covers that would stop it from fitting, so you should be fine.

    £100 is too steep, but I would seriously advise against welding it.
