Coolant leaking from bleedscrew ? *picture*

[marke]

So I have been losing a bit of coolant recently, and I went and had it changed and topped up with G10.
I asked them to see if they could spot the leak and they said they tightened up the pipes and clips where
it could be coming from.
2 weeks past and I have noticed the odd patch of water/coolant under the van when I have parked it.
I opened the engine cover and could hear a "pop pop pop pop". there is a little bubble coming from where
the arrow is pointing in this picture: https://www.dropbox.com/s/sfi2flezp8i0b ... w.jpg?dl=0" onclick="window.open(this.href);return false;
this is the bleed screw right ? I am wondering if it is leaking from this bubbling point.

I'm sure somebody will recognise it but giving your van year and engine type always helps, best in your signature so you don't forget

Thats the one although I've never in ten years owning mine, ever been able to bleed anything from there. I think I'd be inclined to make a simpler coupling if I had to replace it. They do get brittle unfortunately. The only real way to deal with it is get it off and see whats what. Difficult to do anything when its carrying water. They're a rarer part so tend to cost a fair bit. You can weld plastic quite well but it'll depend how brittle its become.

Otherwise, I guess something like this could work with a bit of thought: http://www.ebay.co.uk/itm/Auto-Silicone ... 51c33d5f15" onclick="window.open(this.href);return false;
