PCV valve hose removal?

Hello. I believe you are referring to the bolts that hold the actual PCV valves in place. There are two PCV systems on this vehicle. One is a Fresh air valve, and the other is a Foul Air valve, The bolts are Tamper Proof bolts. They are only used once. You have to cut a slice in them and take them out with a flathead screwdriver. This is probably for warranty reasons; you might have to get new bolts from the dealership unless you can find new bolts that will fit. But the ones in there now are a onetime use unfortunately. The 6th and 7th diagrams are the lines, these are tamper proof too and also a onetime use.

This post is over a year old. Is this a different vehicle? The PCV tubing, valve and hose fittings are not serviceable, they need to all be replaced once removed. If this is a different vehicle a new post needs to be made for it.
