note I believe you mis-read my earlier post of Oct. 8, 2018. I stated in that post that the PCV hose was collapsing every 4 to 5 years not months as you thought, Thanks for your time and expertise as always.
For this system, good. No vac or some at tube it good but no more than 3hg or so, some neg/vac at oil filler is good also, showing PCV is doing its job. Anything positive there, problem. This is where a vac transducer shines for our scopes to diagnose issues such as this when you want to know real engine health. http://www.transducersdirect.com/product-category/pressure-transducers/vacuum-pressure-transducers/.Here is what I find. Oil cap sucked down if placed over filler tube. No action at oil dip stick, no vacuum or pressure.
