In a box? , selling spares then.
I think Kenny is right ... Well I hope, it's a breather , the nipple had this hose on it but it baffles me why the put a bolt in it.
Trying to put the engine back as it should be so I can tackle the vibrations I get.
After removing the egr blanking plate I'm wondering what else was changed, hence the question on the hose with a bolt
