What is this ?

Recommended Posts

There are two tubes (one rubber and one plastic) that split off the connector on the plenum after the throttle body

I Broke the plastic one 996 107 146 00 one which I think leads to the oil separator. However I am interested to know what the thin rubber tube below it (lower arrow) is and where it is leading and Part number ?I found oil in my throttle body and plenum and am trying to isolate where it came from I have temporarily capped the broken tube with some plastic and rubber band ( not driving car ) I ran the car like this and it ran fine.

thanx for the help thus far mickey

Thank you

I capped the 996 107 146 00 vent line at the throttle body and ran some vinyly hose from the separator down to vent to atmosphere

I did this to by pass the emissions requirement of having the fumes from the separator burn through the engine because the separator is gone and it is sucking up oil from the separator because of the negative pressure in the plenum.

And since then no blue smoke on startup and no P1128 P1130 codes ran for about 30 mins. But I will keep an eye on it If I run into problems I will post.

That other hose is a another vent hose for emmissions leading to the oil breather Mickey found me that info
