I thought the same thing. The oil could be effecting the octane rating, so it's very well possible it's more than placebo.

Looks good guys. I'm almost at warranty end so I'll throw it on there after. I like the smaller version that jhn "pioneered"

One thing to keep in mind is it is important to keep is flowing well. If the can clogs up, it will cause pressure to increase in the cases scavenging vacuum can only do so much. And keep it empty. If it fills and sucks oil, it will at least blow smoke out the exhaust, or worse, hydrolock and break the engine.

The can was empty on the inside. I added a downpipe with a bunch of vent holes to the intake side. Then I wrapped that with a pack of stainless scrubbing pads. I also added a 50 micron brass filter to the return side. I replaced the drain plug with a drain cock. I'll be draining it at every oil change, or whenever it's about a 3rd of the way full to make sure I won't be sucking anything into the manifold. The can was about $20 and I spent about another $20 on new fittings and the random parts to go in it.

How often would you recommend emptying the JEGS can? Daily? Weekly?

It vary on car and driving mileage, habits. Depends on how quickly it fills for you. I check mine @ 100 miles or so. If there's enough to pour out, I do it. I don't let it get over one finger amount.

My car occasionally has a rough idle, but then it'll be fine for days or weeks. That points more to sensors or electronics, IMO. Dump a can of Seafoam in the tank every so often and it'll keep things pretty clean.
elziffo, dumping a can of Seafom in the tank will do nothing to clean the valves in a GDI engine, and that's specifically the purpose of this mod, to avoid deposits on the valves.

Not just the valves really, the whole intake path stays cleaner with a catch can over without one..

Also CCV just does not evacuate the crank case as well as PCV did, I find oil in the crankcase vent tube to my air cleaner on one of may cars.. YMMV!

Agreed on the improved engine idle smoothness and throttle response I have experienced from oil separators installed on my 2016 Fit and 2007 Tacoma.

Moroso Overview:
Vehicles from the factory vent these excess crankcase vapors, residual oil mist and moisture right back into the intake manifold which could cause detonation, oil deposits to form in the intake tract including the valves themselves and from lowering the efficiency of the intercooler in intercooler equipped vehicles. Increases engine performance from cleaner intake air.

This looks like a worth while mod. Guess im spending more money now lol, and doing it early on my new 2017. Whether you drive aggressive, conservative, regardless the engine will be running in the 1-5k range, and often holding at 3k on highway speeds. Guess I'll try watching the can on a weekly basis, and see how much oil builds up.

Obviously this video is of a performance car, but the logic is sound, for the cost I think its worth the prevenative maintenance.

Just received mine today (Jegs catch can). Don't wanna [email protected]#k this up, there's a side that is engraved with "IN" is this where i connect the hose from the intake. Pardon my ignorance, still a newbie.

The hose that connects to the top should be on your "out" side and the hose that's coming from the bottom should connect to your "in" side.

That's correct. Pull the hose off the manifold and plug it in to the "in" side of the separator. I have more pics here:

Could be placebo effect or the fact that the vacuum is cleaner, but the engine seems to be running more smoothly as though it's finally getting the right fuel/air mixture.

As someone who purchased their Fit, I'm glad to have a mod that enables preventative maintenance.


mind sharing a link, to what can/bracket that is?

Regarding the flow path, shouldn't the "in" port of the catch can be connected to the PCV side of the circuit and the "out" port be connected to the intake manifold? I believe this is correct, as you're filtering for oil from the PCV system return and keeping it from flowing back into the intake. The description above has it opposite.

Yep. See my post here for my install.
