PCV leak

I have been chasing a vacuum leak for some time I final found it.
The cheap piece of crap PCV valve that I got at the local auto parts place was leaking internally bad. Put my thumb over the open end and the engine idle dropped from 900 rpm to almost 700 rpm. The valve is relatively new, I blew it out with some cleaner - no effect
Who makes a good PCV USA made that has less leakage?
