Whilst cleaning the car this weekend I have found something else which appears to be broken..when i say appears, i'm pretty sure it is broken as its a plastic pipe which has snapped at 2 seperate points. There was only one break in the pipe originally but as i was trying to re-tape it back together (it was taped when i first saw it) I broke another part and have had to use tape to hold that part also. The questions is.... what is this pipe for? It runs from one side of the engine to the other, I'm assuming its an oil breather pipe but am not totally sure. It is made out of plastic and I was wondering if it could be replaced with the correct sized silicone tube or do i need to get and get riped off by a dealer to replace this with the proper pipe??
