Title: pcv fixes
Post by: asht42 on March 21, 2014, 08:28:58 am
Right I'm gonna start by saying sorry for any arguements this causes  :grin:

I'll also apologise as this is my first turbo'd car and I'm not used to all these little valves lol

there seems to be 2 schools of thinking on this :

1 block it off and be done with it

2 add a catch can and drain regularly

which is the better option for say stage 2+?

Cheers
Ash

Best option is to get the last revision OEM PCV.

The TFSI was designed to run with a PCV system so it's not going to do it good having all that crankcase pressure in the head, so blocking it off isn't a great idea.

Catch can doesn't do much for the TFSI, the oil which gets on the inlet valves will still get through the turbo seals so the catch can is a bit of a waste of money IMHO. VRSAlex (admin) proved that after 8k miles that his valves were dirty again.

I looked into it, read everything on the forum and decided to stick with the OEM PCV
