    I just installed a Cold Air Intake onto a 93 Honda Del Sol Si (D16Z6, 1.6L SOHC Vtec), i have a hose going from the back of the valve cover into the intake tube. I was wondering if i remove the hose and install a little filter onto the valve cover, will it cause a problem with pressure, sensoring or anything else?. I want to do this so i can remove the hot air going into the intake tube from the engine.

    I had one, I smelled buring oil every once in a while, so I checked it and it was clogged with oil, and was dripping down onto the back of the block and burning. ill never use one again(theres prolly somethin wrong with my engine, its a piece, im going to rebuild it soon as i get money.

    i had a filter on mine, and put the hose back in. it seems to me that it would be able to complete the vacuum, since your car had it originally, it should be better that way. i could be wrong though

    That port pushes air out, and since the valvetrain is constantly thrashing oil around, you're going to shoot some oil out of the filter. Some people have told me that they could see a fine oil mist coming from their breather filters while running the engine at high speeds on a dyno, but I've never experienced this. I'm not surprised that you were dripping oil on the back of the block. Your breather filter just got saturated and needed to be changed, that's all.

    theoretically you need a vacuum on your valve cover.

    Ya, I'd say keep it on there, the only reason that I could see for taking it off, is if you got a sealed oil-catch can system. Otherwise leave it on, since (for Mass. and Cali guys) the emissions guys really check for that. I replaced my cracked rubber hose with reinforced hi-temp plastic hose, and the guy at the inspection booth asked me about it. I probably would've failed had I not had it hooked up.
