Atmo Catch Can Remove Oil Smell In Cabin

[mrsr32]

is there any way i can remove the oil smell coming into the cabin when the car is moving slowly or in traffic?

in my daily driver, i need to make sure i switch the air to recirc if the car starts going slowly.

or worse case, i plumb it all back stock and just switch to atmo on track. not sure how much that would affect the tune/detonation though.

any thoughts would be much appreciated.

Atmosphere venting is an obvious defect on the street so I would be plumbing it back.

It shouldn't affect t the tune much unless you have heaps of blowby.

Run a pipe from where the breather was to between your turbo and air filter.

There is vacuum in that area when on the power so you get a free scavenging effect too.

As above - that's what I do. If you have too much oil vapour insert another air/oil separator in the line (or another properly baffled catch can).

[mrsr32]

if i do that, can i leave the pcv blocked at the intake manifold? means i could keep the catch can mounted in the car and just swap the return to the intake with a breather filter when i take it to the track and vent to atmo.

Why would you want to block the PCV valve? It's shut on boost anyway. Also what's wrong with running a proper catch can setup at the track? Just because you don't have to doesn't mean you shouldn't.

I'm sure there are legit reasons to do it that way I'm just curious as to what they are

Because racecar.

Because racecar.

hmm, that IS tempting but I think I would prefer a proper setup..

wait, wait... nah racecar status much more important

Plumb it in or put up with it (and the associated risks).

I don't see the complication in that.
