Is any Oil Catch Cans, 2-Port, Universal 3/8" NPT Inlet Outlet can work on Gen3 2013?

no special occ needed for the prius /

 

Yes.

Pretty much any OCC will work. Some maybe more effective than others, or more convenient, better build and so on. OTOH, lots are having good results with cheap one. Ruien? Something like that. Maybe better with extra media, say a stainless steel scouring pad added.

 

good question, I have two occ's which are pretty obvious, but never had a problem with the smog test /

 

Do they pop the hood?

We have squat inspections up here, neither safety/roadworthy nor emissions. And it shows.

My (two, similarly) OCC's are pretty much invisible, looking from above.

Funny thing is, a carefully installed OCC has no negative effects, it's just that it strays from the factory spec.

 

yes, the engine compartment gets a visual inspection /

 

I'd think if you left the screw clamps off the connectors (if you have them) it'd get even less attention. I've been reading up, and apparently clamps are not really needed (even hard on the hoses), with tight fitting hoses pushed onto barb connectors. Especially with the low pressures involved. The more you can make it look like just "one of the boys", the less likely they'll even notice it. Ensure the bracket looks as legit as possible.

 

They're Moroso 85474, attached to the upstanding leg of a slotted angle bracket loosely bolted atop the front cross beam.

From below:


(Looking frontward, with oil pan in upper right corner, for orientation. I've since rev'd the drain spouts, retained the taps, but replaced the spigots with simple/short brass plugs.)

I'm pretty low miles, say 5000 per year. I drain them with Spring and fall oil changes. This spring was the first time with 2 installed, and the second one seemed to be catching mostly water that got by the first. Some additional oil though.

With the single can setup it was maybe 80 cc in spring, 40 cc in fall.

Not sure of the capacity, I think about one cup (240 cc).

Here there's mention the capacity is 7.5 oz, and some discussion and pics:
