I'm new in this forum, but I found some other members may have this problem, I installed triple Webbers in my 280Z 1975, and I have it running pretty smooth, then you may ask, what is the problem?. THE FUMES!!! :ogre:, I "modified" the ventilation system and took out the PCV and put filters on the valve cover and in the pipe that came out of the block. hatch seals are new as all the seals in the body. but driving my beautiful Z is a nightmare. Can I do something to reconnect the vent system (PCV) using my setup?
