Default Moroso Dual Catch Can setup 85510

So I installed the Moroso dual catch can setup on my 2011 STI this past Monday (6/18). They had a booth at Wicked Big Meet and had some pretty good deals!

These cans are works of art. They aren't thin walled aluminum tubing but instead are machined from a solid block.



Here is a picture of the included stainless steel mounting bracket with the factory wire harness bracket mounted to it. I spray painted my bracket with Rust-Oleum BBQ paint so it's a nice flat colored charcoal/black that's heat resistant (good for being mounted near the turbo area).



Here's a picture with my lines run to the PVC valve on the crank case and to the nipple behind the throttle body. Moroso includes the correct size clamps to make certain that your connections are secure.



A picture of the dual cans mounted and plumbed.



Another view.



The fit and finish of the cans are a thing of beauty! They belong on display on my desk! The installation was very easy and they come with a step by step instruction pack and there is a full color PDF available for download from their site.

I had a bit of a coating of oil in my intercooler that I noticed when I installed my Grimmspeed master cylinder brace so I will re-check my intercooler in a 1,000 miles or so and post updates along with what was found in each can. The entire install should take under 2 hours including painting the bracket and waiting for paint to dry and waiting for the engine to cool off.

A+ to Moroso for thoughtful engineering and a great product!

So I pulled the cans apart tonight 126 miles since they were installed on 6/18.

The can on the right is from the valve cover breather lines. The can on the left is from the PCV valve. Clearly you can see some condensation collected from the valve covers. There is definitely some oil mixed in with the fluid. The can from the PCV valve had some oil film in it by feel only.

Mines 85484. Did you get the small or large? Mine's going in a 2011 WRX. Still debating mounting places...can't mount mine on the passenger strut wall.

You might have the wrong kit. Their website says the 85484: Air Oil Separator Kit Fits: Subaru WRX 2006-2007; STI 2004-2007. That might be why you can't mount it on the strut tower.

Mine is the large body kit.

I think you need the 85489 for your 2011 WRX.

Yeah, I can't mount it due to my huge ass TMIC, not the kit itself. I think the kit is universal, the diff part numbers are depending which bracket setup you get.

Would you recommend this over the Crawford AOS? I been trying to read up on these items but dont know much or which one is better for me..This looks like an amazing piece.

I would highly recommend this over the Crawford AOS. A friend has the Crawford piece and it is a PITA. The return hose wants to be kinked, and (I'm sure some will disagree with this but...) since some of what is being returned to the oil pan has some undesirable stuff in it like some fuel. Many will argue that your car doesn't magically make blow by yadda yadda, but the fact is that there is > 0 amounts of fuel that will be returned to the oil pan vs being more likely to be captured in the Moroso setup.

I've had this setup on for a couple months now and I'm really happy with it.

Here is what I found in each catch can after about 400 miles of mixed driving. I'm fairly certain I laid them out the same orientation as they are under the hood so on the left is from the valve cover breathers and the right is from the crank case. The stuff in the left cup is a diluted oily mixture and the stuff on the right is something from the fuel (E85). It smells a bit like ethanol and its not combustible, at least not when I tried to ignite it a lighter.

How bad is it to put this stuff back into your oil? Who knows. I prefer to catch it so I can keep track of the rate of collection and as a bonus, it stays out of my oil.

Its really good IMO. The middle has a divider so all the airflow has to run down under that. Heavy particles would drop out right then and most of the finer particles should get caught on either one side or the other. The baffling also seems to be "serviceable" if needed which is nice. Here is a picture:

So what stops the blow-by going into the turbo inlet hose through the 3rd PCV connection with this setup under boost? That connection is capped off with the Crawford and Grimspeed AOS but not with this one. I'm talking about the hose that goes via the sensor into the intake.

I hope that made sense.

I hope that made sense.
From what I understood from reading through the huge AOS/Catch can thread that is out there is that the top port of the PCV that goes through the white sensor and into the the inlet is always flowing air in the direction from the inlet to the crankcase. Under manifold vacuum, the side port of the PCV has a very strong draw from the intake manifold port that is under the throttle body so this is a source of oil vapor getting into the manifold directly. When I took off my throttle body to install this catch can setup, I could see a pool of oil inside my intake manifold, right below where this port is tapped. When the manifold is under pressure, the PCV closes and the positive pressure causes the air in the crankcase to flow into the heads and out from the top ports on the valve covers.

So the "blow by" comes out of the valve covers during boost and is caught in one catch can. The only other oil vapor present in the breather system is during vacuum and comes from the intake port to PCV connection and this is caught by the other catch can.

Again, this is not my explanation of how the breather system works; this my own understanding from reading through lots of information and I believe it to be accurate. When I was running the G/S AOS, all my oil vapor seemed to come from the heads. The crankcase hose would get oil on the AOS side as if it was drawing from the AOS and picking up some oil vapor so this seems to fit with out the system seems to work. The G/S AOS completely ignores the PCV to intake manifold hose which seems to be the more import crankcase hose to put a catch can on.

Moroso can does a good job in our Rallycross car.



The can and bracket is actually part of Moroso's new kit for the 02-05 DBC WRXs.
