    I'm gonna try to make this as short and to the point as possible...

    I was brought a 97 EX that was wired up and swapped half way done. The motor, a B20/Vtec, was already put together and installed in the engine bay. Well on top of finishing everything up, this kid wants to go turbo. So i'm looking around to see where to run the lines for the oil catch can... Turns out 96+ B20 blocks (maybe b series in general, i'm not sure though) don't have a PCV system. I've searched and it turns out that who ever put the B20/Vtec together was supposed to tap holes in the back of the block and install a pcv system. Well the jack ass who put this motor together didn't do that and since the motor is in already I gotta figure out how to install this catch can.

    I was thinking about installing a 'T' on the port on the valve cover. One end to a vacuum source with a check valve so when the motor is in boost, it's not shoving boost into the valve cover and when in vacuum it'll be sucking out like on an N/A set up. The other end of the 'T' just venting into the atmosphere that way when the motor is in boost, the build up pressure has some where to go...

    Would this work? Any other ideas?...

    The tapping on the back of the block which feeds to the head is for oil supply, not PCV. A catch can is something totally different, but useful as well. Endyn makes a nice setup for the catch can. The Old One - Energy Dynamics You need to supply the vtec head with sufficient oil pressure or else vtec will not work.

    Dude, i'm not an idiot lol... this is what i'm talking about... honda.hybrids.jp - The Hybrid Resource

    This kid wants to turbo and I need to run a catch can which utilizes part of the pcv system... Oil catch can Install - Honda, Acura Tech Website, tutorials, tuning and HOW-TO's. Drag racing, street racing, road racing - C-speedracing.com

    C-Speed's instructions say that if your motor doesn't have a pcv system that you are to run it to the nipple you installed on the back of the block but they are assuming you added a pcv system when you assembled the motor. Who ever put this motor together didn't do that and they brought me the car with the motor already in the bay, so me tapping it myself is outta the question...

    ya i gotcha.

    yeah your gonna need to create a vacuum source from the intake mani. then find a pcv valve that fits the tubing your using. autozone should carry a decent array. the valve is acutally a 1 way valve, like what should be in line to your brake booster, so if your above vac, it wont force the gases backwards, you know what i mean. you would need to tap the block if you wanted to vent the block's gasses, which they kinda just assumed in your link.

    now, mspaint ftw:

    you just wont have block venting unless you tap that hole. make sure you get baffles in the can like they said in the link. helps not gunk up the pcv valve

    btw you see PCV stands for positive crank case ventilation. the v is not valve. the name gives away it's function ;)

    venting the block was my main concern... Thanks for the help though. I was actually just gonna run a check valve, that way when the motor is in boost, i'm not forcing shit into the motor.

    right on. well the pcv will do the same thing for ya, and that's how it's "supposed" to be. if you make it work right, then it doesn't matter tho
