getting my 97 stock c5 ready for the summer and thought i would change filters and fluid when i came across this pcv routing system. i installed a catch can about 9 month ago and installed it per this photo except one difference. i did not block off the port which the arrow is pointing to. dirty side and clean side is as pictured but the rear passenger side port is still hooked up. 48k and runs great. only mod is cai. not much oil in can so far. my other instructions said nothing about blocking off this port. am i ok? thanks.
