    why? it won't do you much good.

    those are mainly for direct injected engines. if i recall, you have high miles on your car. it has performed well so far without it...why mess with it?

    and to answer your question, i don't know many, if any who have installed one around here.

    I could see the good in having this on a high mileage engine, regardless if it's direct injected or not. May not be needed, but could be helpful. Eventually I'd like one on my car, I don't like the ugly mini filter on my valve cover. Let us know what you get, and where you mount it.

    Why not? I have had it on other cars. This car was under warnity till 150k. That is why i didnt add it. And Thought why not. Most could happen is the tank is dry whitch wont be cause my intake hose is covered in oil.

    It's not really needed for your setup. If you were running a Forced Introduction setup like the 10 Gen Civics with Turbo's then yes I would agree that it would help but since you're running a 1.8l NA & non-Direct Injection I see no purpose for it to be honest.

    High mileage N/A port injection can get valve deposits. Im pretty sure the high oil use of my Subaru made my cat fail, if so I'm sure I can find a catch can cheaper than cost of replacing the cat.

    Unless your engine is actually knocking due to knock caused by excessive oil vapor (Ive seen this in the earlier mustang 5.0 coyote motors running the ford racing tune) or your engine has direct fuel injection, catch cans are a waste of time/money imo.

    I've had several cars (mostly performance) and never installed a catch can in any of them and never had an engine issue either.

    R18 PCV system shoots oil back into your intake as the water evaporates from the oil. You can just put one of these off the PCV valve line, and you will get a lot of oil out of your intake. Also if you haven't changed that PCV valve I'd also change it out as well, mine failed at 60k.

    You can then run a catch can off the crank case vent that routes back into your intake. You need a 5/8" plug for the intake boot or else you'll have a massive vacuum leak. Crank case vent is also a 5/8" diameter. I just run a filter off my crankcase for now.
