    I have the same issue now on my Triumph 955i 2002 . This looks a fabric made part, How can I (we) get a sollid gasket again? Tapping screw thread or...

    Mine is the same model and same year as yours.
    How did you get the pipe off, does it pull out? Is it meant to pull out?!

    Ehm mine leaked too and when controling it it went of. I seams like the inner pipe is corroded from the inside (due the coolant fluid) and so..detatched from the housing.
    The question is: How to fix this :s

    Hopefully not an engine strip, but it wouldn't surprise me...

    You could use liquid metal to hold it in place, but it's not an ideal fix.
    I have a feeling we aren't going to get an answer on this one.

    I am not familiar with these motors but functionally it looks like a thermostat bypass hose. Is the stub it attaches to part of the complete thermostat housing?
    If the leak is not too severe you might get away with Radweld or similar in some fresh coolant and antifreeze.

    Looking at the top pic in post #3 it would seem that the pipe is a push fit in the block. Providing the hole is sound then a new pipe fitting should press back in and seal ok. Wouldn’t hurt to warm the block with a hot air gun to expand the hole slightly upon fitting and use some form of sealant to act like glue?

    Indeed. The stub looks like a press fit but maybe flared inside? I cannot see if it is part of the thermostat housing which would be an easy fix (epoxy!) as the hose itself is generic from any auto factor.

    Looking carefully at the pics it looks as if that pipe is fitted into the head and not part of the thermostat housing so needs careful investigation.

    I would suggest a trip to a Triumph dealer if only to find out if the elbow fitting is available as a replacement part.

    If not then you need to look at finding a fitting probably from someone who makes up Hydraulic hoses and tapping the hole to suit.
    If a part is available then there will be an adhesive / sealer / method to fit it with.

    Trying to "Glue " it back in could be a problem as it will be fitted at a point where the two metals will expand at different rates and "break" any glue bond as it will be under Hydraulic pressure from the cooling system.

    @Ste-B It's a pressed part that comes as part of the cylinder head and not available separately I'm afraid. It has been eaten away because the coolant hasn't been changed for some time and has acidified.

    Recommended solution from our techs is use a screw-end pipe fitting, tap the hole, and fit using plumbers tape and loctite. It might not look pretty. but it'll save you having to buy a new head. My concern would be where the rotten end of the pipe has gone.
