Hi,
Anyone know why I get a horrible vibrating noise coming out of the crank breather hose?
It's usually worse when the engine is cold and ticking over but can come back at any time.
I find it annoying when sitting at traffic lights and people give the car funny looks as if to say "bag of shit"
It's an 86 325i engine btw.

Cheers,

G

Split in the pipe?

Hi Brian .. no I don't think it is.
It's been going for 5 years now ... When I had the original air filter box it made this noise and I couldn't work out where it was coming from.
Now I have a tiny K&N on the end of the pipe and it still does it.
The noise comes directly from the end of the pipe.
