Coolant leak identification

[ballast]

Hi

I've got a coolant leak that only seems to occur when the engine is very hot (left idling for quite a while at the MOT this morning). I'm wondering/hoping someone can identify the part for me where I think the leak is coming from. It looks to be in a really difficult to access location, but then most things are!

Any guidance really appreciated.

On the pic, the top pipe with the clip (light blue arrow) seems to attach to a unit (dark blue arrow) which has a solid connector (presumably attached to the unit) within the yellow circle.

Can anyone shed any light please? Sorry about poor pic quality - underneath it, very hot and hot coolant...

Just to help with location/orientation, this is nearside rear, just in front of the rear axle looking directly upwards (effectively towards the coolant reservoir, but further back).

Thanks

Chris

The pic quality is so poor, it's invisible.

Maybe if you cant post it here, post it elsewhere and link to it?

Sorry, couldn't attach it - flippin' thing. Now with a link (hopefully!!) to the pic...

At the bottom of a reply...

Filename - "Choose File". Browse for it. "Open"


Then "Add attachment"

then "submit".

EDIT - Ah, I see you've added a link to the first post now.

Is that not the OSV up there? It's the right location and made of plastic.

 

[ballast]

Yep - that's what it looks like.

OSV?

Thanks for your assistance identifying - so assume this is the oil separator (valve?). This has a coolant connection then (seemingly at the top)?

Thanks
