nedd help with this valve

I can see it's definitely not a diesel, but I'm not familiar enough with the gassers to be able to determine if you have a 6.8L or a 5.4L engine by looking at the picture.
As well, what year is your Ex?

I have been reading about this and some vehicles got a heated PCV valve. I don't know what years had it or why some did and some didn't. There were some that used coolant to heat the PCV valve and others that used an electric heating element. The heated PCV valve was apparently used for climates that stayed very cold for long periods of time.
One post suggested that the PCV valve itself was replaceable separately from the heater assembly on the ones that used coolant to heat it. On my V6 I replaced the entire thing as an assembly.
The leak is most likely an issue with the very small heater hoses and the spring type clamps. The hoses should be replaced due to age, and if the clamps are not aging well they should be replaced also. I tend to prefer worm gear type clamps instead of the original spring type clamps. But in some tight spaces one must use what fits.

Our 2002 Socal Ex has one, maybe it's an emissions thing in CA.
It's a 1/4" line using engine coolant for heat.
It could be bypassed with a 1/4" brass splicer fitting and I doubt it would affect anything noticeable.
