[Bmcu] TR4A P.C.V. VALVE

[Jeff]

I have a valve

that I don't really know if it is bad.

When it is idling it idles about 1500 rpm, but when I plug the hose that
goes into the valve cover it drops to about 700.  Is that normal?

I've replaced the rubber diaphragm and that had no effect.  I don't know if
it's the Valve or a problem with my engine letting in air (not good, it's
supposed to be sealed)

 

Thanks

67 TR4A with a fast idle.
