I sure am glad I went this route for my home made catch can. Two trips to Kentucky (a beautiful state) from Wisconsin...22 days of fun and 3200 miles. Once home, I drained the "water " and removed the lower portion of the cc...not only a pint of water but all this crud. No way would I want a drop of this junk going back into the engine not to mention the clean and dry intercooler pipes.
Ugh, that's nasty stuff. Makes me wonder whether I should go forward with adding the catch can that I have (that I haven't installed yet, need to fashion some kind of bracketry). Seems like not allowing the vapor to condense in a can is the less messy alternative... But, I reckon I should install the can eventually.
That's basically an emulsion of water and oil (like mayonnaise). I agree it makes sense to keep it out of the engine. What's your catch can install look like?

I'll have to search, I posted pics in a different thread. Basically made out of 4" PVC tubing about 6" tall, capped on both ends, vent holes on top along with the ccv hose nipple, bottom has a drain port and is also removeable. Beats installing these (high dollar) catch cans made of CNC aluminum, they still vent back to the motor making them pointless, like I said I don't want to see a drop of this crud in my engine.
The stuff in the bucket looks bad, but in a matter of speaking it’s not as bad as it looks. Our unmodified engines can and do last many hundreds of thousand miles with only routine maintenance. The vapors that are recycled through the ccv system are vapor phase and not the congealed mess you will see in a catch can. What the engine sees is water vapor (a product of hydrocarbon combustion) and hydrocarbon vapor mixed together and consumed while still in vapor phase.
That said, I have nothing against anyone using a catch can. I’m sure my 2-stroke power equipment spews much more oil and unburnt hydrocarbon into the atmosphere. I just wanted to put it out there that catch cans aren’t keeping the muck you see out of the engine. That muck is a result of the catch can allowing the vapors to condense together.
Understood, and I realize the mess looks worse.........but its the moisture side of it mixing with the EGR gases that create the black goo I'm avoiding.
Some questions before I get started,
1. Do you ever smell the vapors in the cab?
2. How did you connect it to the engine? Did you connect to the factory CCV hose somehow and then put some kind of plug on the intake port?
I did the exact same one as the e-Bay unit. Sure it might be chinese, but I'm sure the other ones are too. So the cheapest price got my cash. Install was a breeze too.
