Is that a catch can? Yes it is. Goodbye CCV

So after installing a new CCV the oil drips are still present. I just wanted to do away with that damn thing once and for all and did a LOT of research off this site and some on this site. I left it vented to the air for now so excuse the foam filter. It was the only one I could find locally that would fit. The car started right up, no codes, dash lights etc. The CCV is still attached to the engine I will be unbolting that damn thing once i have more time. I just plugged the vacuum ports on the distribution piece and fabbed up my own connector from the valve cover using the connector from the old CCV. One thing I did notice was a lot of oil in the distribution piece vacuum nipples. Eventually I will have a closed system again. Just waiting on a PCV to come in used for Audi/VW 1.8T engines.

One thing I noticed while driving on the new setup was that the engine tone sounded different, can't really describe the change but the I6 sounded more pronounced? Also the car fell better during acceleration. That may be due to no more oil being sucked into the intake. Stupid new cold weather CCV.

Here are some links that helped me including the PCV valve I will be using to recirculate and the catch can I used. I chose it mainly because of the internal baffling and the 3/4" fittings:


Also thank you to Poolman and CN90 from this site. Your articles were a very good read regarding the PCV/CCV system!!
