ghetto oil catch can/breather - ScottyB - 02-17-2004 i made a pretty decent breather for my car today. the basic concept was that i put a fuel filter inline with the breather hose (which then connects to my intake ahead of the TB) to catch any oil vapor. i've seen pics of it done to other cars and it works, although not as well as a $200 oil catch can. overall i spent like 10 bucks. here's what i used: clear fuel filter from autozone - 3 bucks clear pvc tubing from homo depot - 5 bucks some collars (the kind you screw to tighten) from hd - 2 bucks i kept the rubber hose that comes straight off the valve cover, since it fit the fuel filter fine. so i put a collar over the rubber tube, and tightened it to the fuel filter. then, for the filter-to-intake connection, i cut a piece of clear pvc and connected that up with collars. and la-dee-freakin-da, we have a ghetto breather. i realize this thread is worthless without pics, so i'll have em up tommorow - .RJ - 02-18-2004 Why? The honda breather system flows *in*, not *out* If you want to catch oil vapor before it recirculates into the intake charge, do it off of the PCV valve, in the tube leading to the intake manifold.... with a catch can. However i honestly do not think you have much to make issue of... - ScottyB - 02-18-2004 yeah, my fault, its coming off the pcv. i just figured i'd do it as cheap insurance. i know i dont really have anything to worry about anyway. i'll post a pic tommorow, so it's clearer. - Mike - 02-18-2004 sounds like someone was mighty bored of assessment day. - .RJ - 02-18-2004 If it connects to your intake ahead of the Throttle, its the breahter, not the PCV... - Mike - 02-18-2004 - ScottyB - 02-18-2004 ok, in that case i screwed up, since my connection is before the TB. question: you're saying the crankcase breathes in? i thought it was always trying to push air out, since the crankcase is under pressure. - Mike - 02-18-2004 Granted this for a B-Series motor but the concept is the same w/ an F-Series. - ScottyB - 02-18-2004 thanks for clearin that up mike and RJ. i basically forgot the air-in concept and didn't think to even look at the pcv. well at least i didnt break anything in my mad experimentations :roll: - Mike - 02-18-2004
