What are you catching? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

So I'm considering a catch can and have seen varying amounts of oil captured. I'm hoping to compile some results from everyone in one place. Here's the question to everyone with a catch can (and it would be really great for the FI guys to report in) :

whats hooked up to your catch? pcv/breather
Where are you terminating (atmosphere, manifold, cai)?
date of install?
how many miles on the can?
qty of caught fluid?

Interested to know what you've found.
I must drive really slow because in two oil changes I have used no oil.

bump it.. i am considering a catch can... so need more info if it will have any effect im daily driving though highly spirited most of times..

Moroso oil/air separator plumbed into the PCV.
Installed at approx 2,000-3,000km's, the car has just passed 6,000km's.
Only very occasionally winding the engine out on the street. One track day.

I only just opened it on the weekend and there is bugger all oil in it. I was worried it may have been passing through, but the outlet into the Plenum is completely dry. So seams to be working.

Below is a pic of the opened separator.

what setup is yours ?

mad_sb · 05-01-2013, 08:11 AM

I don't think your going to catch much on an NA engine but i want to see everyones results. I have not checked my saikoumichi (closed system, pcv to intake manifold) in the last couple thousand miles. I did check it after about 500 miles and nothing came out. I know it works because it caught a LOT of oil on my ralliart (also between the pcv and intake manifold). I have a second can i need to plumb on the intake side this week.

THE CLAP!

This was after about 1K road miles after install and two autocrosses. Some spirited driving but mostly my daily commute. Radium can hooked up only to the PCV. It's not really all that much, the angle kind of makes it seem like more than it is, but I'm glad it ended up in the can and not in my intake manifold.

are you boosted ?

xwd · 05-01-2013, 07:30 PM

No, just have a Perrin catback and a drop-in filter. I would consider a catch can a necessity on a boosted car. I would highly recommend it on a NA car as well.

It's closed loop, plumbed inline with the PCV. The line on top of the plastic intake plenum. Not the breather hose.
Below is what I'm using. The type with the tap on the bottom.

I agree, unless there is something very wrong you shouldn't have much blow by on an NA car. It was an impulse buy I made shortly after buying my car.
