Since the turbo's coming off for a bit of fettling, I got to work on replacing the cr*p standard breather, which by the way is much smaller than a standard Escort RS Turbo one! lmao
After taking it off last week and flushing it with petrol, it was obviously blocked with a lot of gunk, which later led to some oil being passed through the turbo on the induction side.
Bought this nice stainless item off a mate for £10

Seems to do the job nicely
Stock breather in place...
New one in place (anyone got a spare jubilee clip? lmao)
