Hi, I have a 2.0L 8v GTI mk3 and I have alot of mayo like muck in the breather pipes (cleaned out now)
but the black round part that sits on the top of the rocker cover look quite full! and I cant see quite how to get it off!?? it looks like it just pulls up and off! but dont want to pull to hard and break it!
what do I do??

and dose anyone else have troubles with this blocking up with muck???
