Catch Can
Has anyone installed a catch can on their tow vehicle? Is it worth it?

I'm probably the only dummy that doesn't know what a "Catch can" is?!
What does it catch?
Brian.
PS - EDIT - oops, guess not, Michael doesn't know either!

I know what a catch can is, just not in this context. I love a good mystery.

How many cans would a catch can catch if a catch can could catch cans?

What i have read is they claim to capture oil before it gets to the inter-cooler on a turbo engine. The problem there is that oil is no coming from the PVC valve, and thus collectable, but from the turbo bearings and not collectable.

Me to dummy as to only one I no of is when we raced stock cars collected water when ran hot. Raced motor cycles flat tack grand national circuit all air cooled no need, if engine blew oil went every where no way to catch. Maybe will get follow up what it's for.

First time I heard term couldn't figure out what it was all about, but it seems Honda and some other vehicles spit oil, sort of like a tobacco dipper.
Tried linking to website but link didn't work, but if you google search catch can Honda Fit forums you might be able to see a diy build of one.

Post below shows catch can is the blue can in the middle

Until the op responds back all is speculation as to what he was talking about. Have fun🙀

In the F150 Ecoboost world some owners drill a drain hole in their induction system and run anything that drains out into a "catch can" that they can empty at their leisure. The early adopters were worried about a condition where operating in a high humidity environment would result in a water condensate in the crossover tube that could be sucked into the engine under hard acceleration resulting in at best a shudder and, at worst, the engine going into "limp" mode.
Later, performance enthusiasts advocated the use of the cans to more or less defeat the EGR system and keep the nastier recapture fluids and condensed vapors out of the engine.
It seems extreme -- take your brand new Ford home and drill a hole in the intake system?

Some "catch cans" capture the oil-mist prior to the PCV valve to prevent it from allowing crankcase blowby gases from re-entering the intake (as designed) in the belief it's bad for the engine and dirties the throttle body on fuel injection engines.
They "prove' their point by showing the dirty condensate they drain from the can every once in a while.
An argument almost as good can be made that the condensate is actually good for the engine as a free upper-cylinder-lube... that is, until you captured it in a catch can you have to empty regularly. (If you ever let it fill up it may dump a whole bunch more than the original design planned-for... and all-at-once....which can't be good.
I figure all the EPA mandated controls and CAFE mileage mandated for cars these days... take the PVC emissions into account and it's just a feel-good gimmick without real virtue. (My non-catch-can Jeep made it to 323K miles before it was rear-ended by a woman texting while driving a Class A motorhome pulling an Indy-type racer at 70 mph.... So I figure a catch-can is not needed and I never had to service it.

The mystery continues. Do not suppose we will ever know what the OP was actually asking about.

We've all been caught in the catch can.
