Here is my setup. B20 (injection ports plugged), with two SUs mounted on the combination cast iron manifold (secondary butterflies removed and plugged). Using the B18 PCV system: Crankcase breather box on side of engine through PCV valve to what looks like a large orrifice nipple on the manifold. Oil cap hose goes to air filter.
Problem is that the PCV valve (less than a year old) rattles like crazy clickty clickty clickty. The valve seems to be functional as I can suck through the hose but can't blow into it (mmmm yummy oil flavor).
Other things I noticed. The engine dies rather quickly when the hose is pulled off of the manifold (duh), and from a subjective feel it seems to suck pretty steadily when I put my finger over it. I looked in the archives and all I could find is that someone else had the problem so they just removed the PCV valve from the system.
What is the deal?
Am I using the wrong nipple on my manifold? Should it have a more restrictive orrifice? Does it sound like a bad PCV valve? Is this pointing to another problem? I really want to avoid going to the B20 pcv route since that would involve going over the whole thing again and trying to find the right size hoses and everything.
thanks,
