Hi all
Maybe someone can explain to me how the PCV valve operates on the TR4A. There is a diaphram which seems to block the plate and some kind of spring loaded plunger that sits in the hole going to the intake manifold. I just rebuilt the motor and when I turn it off there is a hissing noise that persists for about 10 seconds that sounds like a vacuum leak. Also I am having some trouble setting up the carbs. The Brits call it "Lumpy tickover"
I have seen a number of threads that suggest dumping the valve and replacing it with the old style (vented cap or vent pipe). Moss sells a complete PCV for $55 or so. What to do?
