i was wondering if i could delete the rubber suction tube going to the turbo and put in a hard suction pipe instead. since the bov is a recirculating one should i just not mess with it. i also have a oil catch can but could not clearly find a write up on where to install it.

remove the hose running from intake manifold to left cam cover. cap both the intake manifold and cam cover. leave the small hose between the to cam covers. remove the hose running from right cam cover to hard pipe. catch can goes between the hard pipe and cam cover. if you have an american style catch can with only one hose and filter. cap the hard pipe and connect to right cam cover only.

keep all stock hoses and return them to factory location before emissions testing. they have an extremely small affect on emissions but it might make the difference between pass and fail. not sure how strict your local testing is....
