I've got a '74 2.0L D-Jet motor in my car. The PCV valve has nothing inside of it (no spring or valve) so it's basically a port on the oil filler. I've got it hooked up to the airbox, like L-Jet. I can't hook it to it's stock location on the plenum as it'll over-rev the motor at idle.
I've noticed that there is oil on the inside of the plenum, presumable from the oil fumes coming through the PCV valve. Is the arrangement I have ok, or should I try and find a PCV valve. Do I risk fouling the plugs? The car does not smoke. |

yes it was...and they did away with the head venting too. Different setups totally.
If you have the early setup use a PCV valve or install a plastic ball with a 4mm hole drilled init to meter the air pulled into the plenum..The crankcase must be vented or the blowby pressure will blow out the seals. (IMG:style_emoticons/default/chair.gif) |
