Anyone Ever Replace PCV Valve in their Base Model?

Not a known issue but I think older V8's need the revised part which allegedly does a better job. Not sure when the new part started but there's a blue dot on the inside or something...
Realistically, they should last 80k+ miles but just do it the next time you do the spark plugs (which is supposed to be every 30k-40k), its 3 bolts and unplugging 2 hoses. The part is like $150?

oh i looked it up that part is external on the V8 engines so probably much easier to replace. Thanks.

My diagnosis based on codes and vacuum leak at PCV clearly indicate a leaky PCV valve diaphragm. I have seen a thorough YouTube on the operation. It doesn’t appear complicated, but it looks like many of the components are tough to get at (what else is new with any modern automobile?)
Has anyone tackled this? If so, would you do it again? Any cautions or pointers?

03/04 Cayenne's had an external PCV part 95511076500. You can purchase an aftermarket one for about $50. The 958's PCV can be converted to an external one using 95511076500 and a couple other parts.
I've run it on mine for about 8k miles now with no issues. All you are doing is moving the location of the PCV "downstream" about 6 inches. It only takes about 30 minutes to "convert"/fix the torn PCV.
