    Found coolant leak - what is this part?

    Hi guys,

    So I've been losing coolant recently, was worried it was off the recent turbo work I've done, but no worries, that's fine. I found the leak on the right hand side of the head, underneath a 4-way coolant junction that bolts to the head via 2 allen key bolts (where the temp sensor plugs into). I've attached a picture of what I can see.

    I think it is this 4 way junction that is leaking given where you can see the pink coolant on the gearbox below it. However, there is also something I've circled in red which also appear to be wet - but I don't know what it is or if I should be investigating that too.

    So, could someone help out with:

    1) What is the 4 way junction thing that bolts to the head? Does anyone have a part number for this? Do they usually leak when they get a bit old?

    2) What is the other part that appears to be wet? Should I be worried about that?

    Thanks guys!

    Aran

    They usually crack on the molding seam, so seem normal once off....
