The new one is from reputable dealer but I believe they are all over seas made.
Thanks in advance.

I was not sure if the test as a pressure or vacuum test and what are the specs. Like the newer valves that have a spring and the spring wears out and the pcv leaks. That valve can be assembled with a multitude of springs rates. This one seems “looser” than others. I also want to put a gauge on that port to see what type of vacuum the engine is pulling and see if maybe the engine is pulling more vacuum than the pcv can handle and it is staying open always. In which case it’s garbage and I need to find a new way to evacuate the crank case.
They say to replace the Crankcase Ventilation Valve every 12 months. Excessive? Just spray some Gumout?

You boys are sure making me feel old. Here is the tool for measuring the effectiveness of your PVC. On a running engine pull off the breather on the v/cover opposite the PVC. Lay device over the hole. If there is adequate vacuum in the crankcase the check ball will be pulled into the safe zone.
I guess I'm old too! I used to have one of those testers......I wonder what happened to it? Hmmm....You boys are sure making me feel old. Here is the tool for measuring the effectiveness of your PVC.

because every engine, even factory fresh, is never exactly the same as as the one next to it. the factory valves were probably a "best average" type of guess. whether you use one of these or not, there's some interesting info HEREI understand how it works but just could not find a spec to test when it “pulls open.” After all the dialogue- I now assume there is no spring or spec. thank you!
