I have a boosted gsr..... I have been running a filter on the valve cover. I just recently noticed some blow by. Im wondering how to set-up a catch can? I saw something awhile back where you have to put a plug in the back of the block and get some fittings from honda. I think I would like to go this rote if someone could get me a guide to it. THANKS

 

boosted hondas lack in this area, since we no longer have the vacuum from the pcv you need another way to let the crankcase vapours escape..you can tap your valve cover and run it to a catch can, aswell as running it pre turbo

 

go to google and search for the official crankcase tread. you can follow that or get a valve cover welded with fittings and that will relieve the blowby as well. i am selling a catch can if you are interested...
