ive been hearing a lot about occ and how to install them but iv also heard that if they are not done right you can get too little vacume or to much, which will cause more blow by in the piston rings. to do that you also have to mess with the pcv. how do you tell if the pcv is leaking or not??? can you put a occ in with out causing the piston rings (positive or negitive) stress??

 

use a good quality thick fuel hose to hook up the CC. Hose that wont collapse after heating up. My gauge still reads the same as it did before the OCC. I am still debating on doing the check valve mod, cause i havent seen any long term affects of using one.

 

correct me if im wrong, when you put a occ in you dont need to mess with the pvc valve? well thanks for you help i was begining to think that no one was going to reply
