I'm getting a really bad fumes smell in the cabin while driving. I had the front part of the exhaust changed as the flexy joint was blowing but it's still there. While having a look under the bonnet I've found a lot of black crud and diesel around injector number 1
Now I don't think the to of the head could get hot enough to start to burn off the diesel if it was just a leak form the return spill pipe or something so I'm thinking maybe the injector seal is leaking and letting stuff (diesel and fumes) back out of the cylinder Possible? The smell I'm getting in the cabin is not diesel, it's defo combustion gases, I don't think you'd really smell a diesel leak would you?
Is it possible to get new seals for the injector? I don't really want to buy a whole new injector.
