420A new question about my car

[josh_effin_tyre]

Hi guys I would like to start by saying my automotive knowledge is in carburated engines and stops there, but my wife has shown me the joys of owning an import. While I was cleaning my throttle body I noticed alot of oil in the piping for my cold air intake. I realized it was coming from a hose connected between the pipe and the valve cover so I disconnected the hose and blocked it off, probably a bad idea but oh well. I later noticed a tremendous vacuum on the oil cap while running however it seemed as if the car had a new lease on life, it was more peppy and the exhaust even exited with more force. I still have the pcv attached, hence the vacuum, will this hurt my engine? What if I opened the hose and added a small breather? I'm lost here need some advice, I like the small but noticeable power increase but don't want to harm the engine

I'd recommend getting one of those inline filters to catch the oil at least, preferrably a catch can. You dont want to block it off entirely, it helps evacuate crankcase pressure.

Yeah I knew I shouldn't leave it like that but that little boost was nice. Can I do the same with the pcv? On my big block I just used a mini breather but that's apples and oranges. I'm sure if the hose producing vacuum is leaving blow by the pcv valve is as well

If it's not going to blow out whatever you put there sure.

Thanks for the info, it's a little easier to understand another dsmer than a website. I got into a car accident in 2008 because I was hotrodding around town and got brain damage from flipping the truck, so the technical explanations take a while to sink in now .
