After all this work a few test runs at full throttle has no hesitation at all.

About $400 in parts and cleaning supplies and 7-8 hours labour was my cost.

I think that checking/replacing this PCV/check valve should be done every 5 years or so. Our car was 11 years old when done and the hoses were exceptionally brittle and partially clogged - well past their replacement date.

I'd post pictures but they are too large for posting.

Regards,
Paul
