Seems like I've seen it both ways, but is the hose coming off the PCV valve supposed to go to the passenger side of the intake of to the back of the intake? Thanks!
Ya know, I don't know for sure if it was correct or not, but the PCV hose on my 67 went to the passenger side of the intake. Doug
If I remember correctly, the 67 500s PCV valve hooked to the nipple under the air cleaner. If you have a original air cleaner. This provided little if any vacume. So it was commen for people to plumb it to the intake.
