Jackson Posted July 5, 2011 Report Posted July 5, 2011 Hey, Is the crank ventilation the pipe on the carby that is larger then the others and comes down at about 30 degrees? Thanks Quote
altezzaclub Posted July 5, 2011 Report Posted July 5, 2011 (edited) When you're driving air goes out of the crankcase via the PCV valve in the tappet cover and into the inlet manifold. (Yellow dots) That air is replaced by fresh air going into the crankcase from the airfilter. (Green dots) When you're idling the PCV valve is shut and fumes go out the 'inlet' to the air filter. (green dots) Stupid system isn't it, the inlet and outlet are so close together it doesn't flush the crankcase at all! Edited July 5, 2011 by altezzaclub Quote
altezzaclub Posted July 5, 2011 Report Posted July 5, 2011 Stick up a photo and someone will tell you. I gave my stock carb away & can't remember it. Quote
