What\'s this bit do?!
Just replaced the N75J valve on my 1.8T. To get to it I had to temprarily remove a black circular part (approx 5cm diameter)... a rubber hose from the middle of it joined the air intake, and another hose joined onto a metal pipe (which looked like a breather pipe), fitted along the side of the cylinder head.
What is it?! [img]/ubbthreads/images/graemlins/idea.gif[/img]
When I removed it some oil poured out - is this to be expected? Also, one of the hose clips was very loose.
All back together now, and seems to be pulling more smoothly.
Re: What\'s this bit do?!
Sounds like something to do with the PCV (positive crankcase ventilation) to me, they normally have a habit of collecting a little oil, nothing to worry about I don't think.
