Hi everyone.

I have a small coolant leak that makes me add a little coolant every day. Upon my first inspection I saw some dry coolant over a part. I just don't know what it is. I have attached a couple of pictures of it. If someone can identify it for me.

Many thanks. Here is a close up of the circular thing.
Seems to be coming from the hose or underneath the circular thing.

 

If you have coolant going into your PCV valve you have bigger issues for sure. I'm hoping your diagnosis is wrong!

 

Hi Fernando

IMO it is very unlikely that the coolant is coming from the round valve which you point to.
It is a PCV and controls the flow of air from the sump to the TB.

The leak may be from the small hose on the head tank where the jubilee clip has been

fitted.

There might be some evidence of leakage under there also the clip has not been fitted properly-it looks a bit too far back and not on the nipple properly.

Check the nipple for cracks also.
