Hi guys,

Does the IS200 need the PCV valve, or can I just vent to atmosphere with a breather filter installed?

If it is ok to run without, will I then have to plug the pipe going into the inlet tract?

I don't think you 'need' one as such considering many boosted IS300 peeps have removed them entirely without ill effect. But I certainly wouldn't put a breather on the end as any oil will just back up in the filter.

I think if you intend to remove it, you should have it go to a catch can, which is then in turn vented to atmos.

What Jim said!

I had mine plumbed into my induction kit, and it dumped a load of oil into the back of my charger! Catch can is the way to go.

you will need to plug the breather pipe, if not you will have a massive air leak and the car will not run.
Silly question, what gains will this give you??

Same ormi, I would much prefer a sealed breather and let the engine/breather do as it was designed to do.

No specific performance benefit guys, it's a purely cosmetic thing.

Experience from other cars lead me to believe what has been suggested already, but I just needed confirmation really Smile

Thanks again all.

ormi to the above............none dont see why you remove this...

Ormi, yours is plumbed like mine was, do you not find oil is pushed into the induction kit and into the intake of the charger? I don't know that this causes any real problems? But I didn't like the look of it!

Compressing oil can never be a good thing I don't think. I suppose it might not be _so_bad for the TTE Chargers as they are twin screw type aren't they? it's more damaging to impeller driven compressors where the oil can be enough to damage the fins when they're spinning at a billion RPMs
