I'm not sure how much 'trouble' that would be - but it 'seems' like too much trouble for an inconclusive test.

I'm assuming at this point that the consensus is that the oft-mentioned 'vent tube bubble test' is not really a usable test for CCV operation.

Given that, yet given my high vacuum test, I need to re-read the CCV testing thread because I find it hard to believe my CCV is toast because I have no 'other' symptoms of a bad CCV (smoke in exhaust and/or loss of oil over time).

I lament a nice, simple, definitive test for a bad CCV (but maybe I just did it all wrong so I need to re-research).
Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
