It looks like this must be blocked or broken in some way, as when I start my engine up from cold, it seems to leak petrol from there, and it really stinks of petrol inside the car when that happens!
Is this a common type of problem on the C14SE? Is it expensive to replace? My car might be going in for a service this weekend so I was thinking of getting my mechanic to change it.
Come on someone on here must know?
Well, I'm not claiming to 'know' but I don't think it's supposed to leak petrol, so change it, or at least ask your mechanic about it (it may be leaking petrol due to another fault, say blocked breather etc).
