Good evening crew!

I could do with some advice however it seems that this forum doesn't accept videos, so I've needed to learn how to post to YouTube LOL.
Last summer I replaced my SJP, after-run pump and a bunch of hoses and general maintenance. Shortly after doing this work I noticed that I had a bit of a coolant leak, but couldn't find it. Took it to a garage, put it on the ramp and still could not tell where the coolant was leaking. Long story short, it's the coolant pipe from the hot-side of the turbos (during normal operation) going to the after-run pump located under the intake manifold.
You can see the cotton threads burping fluid, so I am assuming the pipe is damaged internally. The pipe sure seemed fine when I put things back together and I tried to replace clips and pipes in the same location/orientation as removed. I guess it is a 22 year old pipe and it does handle the hottest water, so maybe given up
It's possible I have put the clamp on too far down from the end of the pipe (need to check photos) and thats caused this problem?
What would you do? I'm guessing I should lift the intake again and replace the pipe. But how do you even get to that pipe from inside the engine bay?

It's this pipe circled in green...

Thanks in advance

Evening Craig,

Unfortunately I am in no way able to give any advice on this topic. Hopefully some of the of the experienced guys can help re access to the pipe from inside the engine bay. No comfort i am sure but at least you know how to get the intake off. Fingers crossed it maybe the clip position. Look forward to seeing how this is fixed as I am sure we will likely face this ourselves at some point.

What a faff. I would fabricate a bit of pipe in stainless and make a section to extend the pipe.

Thanks guys - ironically on a long drive it doesn't leak much at all, it's the shorter drives that it's leak pink coolant in the snow
I really don't want to pull the engine for a stupid leak, so will consider what Ben has suggested.
However that pipe is not a constant size. It starts at the turbos as a 12mm and ends at the pump as a 20mm, so not so simple...
