which is small and you can see through it, so probably has little change in vacuum compared to larger ones.. easy to drain and see oil level obviously.. also has filter inline which is probably great compared to baffles..
might be harder to install, but its probably a better catch can.. more volume etc.. probably one of the better functional ones for the money..
I don't care about looks at all, just function! getting my new intake in and used Sea Foam and I dont want any sludge in my damn intake manifold any more.. lol
Problem with the Moroso is it only has an input, no output. An oil catchcan needs to accept an input from the crankcase, and then vent the oil-free air into the IM.
If I had to pick between those two I would go with the ebay thing. However, I recommend you go with either a regular oil catch can or this Catalytic Catch Can review
EDIT: I just realized the size of the reservoir on that eBay "catch can"... do you realize how often you are going to be emptying that little thing out?
hopefully not to much lol, i mean if THAT much oil went into the intake manifold, then people would have to constantly add oil to the engine! whenever i check the oil its always at the same point..
well i put together my own kit for $9.xx today, well see how much crap gets in there.. its not hard to empty it out anyways... even if i have to every 500 miles its worth me saving $90!
Wow, that catalyst can looks pretty cool! I wonder what the catalyst is actually made of. Only thing I wonder about is that almost all the consumer reviews seem to be on diesels or older carburetor cars. Probably not as great an effect on fuel economy in a highly tuned Honda... hmmmmmmm
Garn - why did you hook up the hose that is supposed to go to the intake. You're supposed to have a fresh air source for the system to work properly. Right now there's no way for new air to replace the vented crankcase vapor
its still connected to a vacuum source, just on the intake manifold side, thats all the really matters, the crankcase breather is also oily air and i didnt want that going to my intake tube.. the pcv valve is only open part of the time anyways...
It's connected to a vacuum source but it's not meant to be a closed loop system at all. Think of it this way - you're sucking out crankcase vapors via BOTH tubes now, with no way to replace that air besides whatever is getting blown by during combustion. Which means something is not going to be running correctly.
What's meant to happen is that crankcase vapor is sucked into the IM via the pcv valve. However, now you need a new, fresh air source to replace the air you just sucked out. It takes this from the filtered air coming through your intake. Yes, sometimes some oil does go up that tube to your intake but not nearly as much as through the pcv tube. If you're really worried about oil getting into your intake pipe I suggest putting a breather on your valve cover in place of the tube running to the intake.
I'm not sure of how much a difference this would make to your car but I think in the long run it could be a problem, and it may be the cause of your high idle. The IM supposedly gets close to 20% of it's incoming air from the pcv system, which you have now just interferred with. Hope that helps.
the material shown in ebay picture, i remember reading someone mention about it's not design for filtering oil, awhile ago, someone else made one out of fuel filter
