Purchased this car a couple of months ago and have finally got it out of storage. Knock sensor went out so I'm upgrading to the newer style along with ls6 valley cover. Noticed today that the rear of the passenger side valve cover is missing a breather port everyone else seems to have. I can only count the front passenger port and the rear drivers side port. Just curious if anyone else has ran into this on different ls1 motors. Just trying to learn more about this platform. Excited to be part of this community as well!
