Oh not to worry . How much of the car did you have to dismantle to get the box out?
If you haven't sorted the breathers yet, I bought a great little manifold off ebay for mine
Neil, could you take some pictures of the process while you're doing it please? Mine is also full-o-splendid and I think seized too.
When I eventually sort it out I was thinking about running a second snorkel for it.
The Halfords one is a lot shorter than that, and also isnt a ball end. I think I might have to invest in one!
Is it an 8mm one and have you got a part number?
I have the allen key bits you mention, as I have the large Halfords set. Problem comes with the fact the bolt is that close to the pipe, it doesn't fit!
Tried it with tape round it, then tried this evening with dad turning it while I supported the UJ and it still wouldnt shift
So pending weather/panto set build/motication I'll be cutting the downpipe for better access!
Oh, I forgot to mention.... its been changed sometime in its life for a stainless cap head. I think because the shape of it wouldnt let a normal bolt fit!
