[Shotimes] PCV extractor and vacuum in crankcase

[van Oss]

Crankcase outgasses can go any of three places:  1) into the intake to be 
partly reburned and partly gunk up the works 2) into a temporary tank to be 
pooped on the street, or 3) into the cat-back.  If there's a question about 
the value of crankcase vacuum, I refer you to Paul and Smokie.

p.s.  General principle:  Cripes, Kegel, you're the one asking about whether 
something is worth the trouble?  You, who used to glove up and scrub sterile 
before prepping your car for the convention show?   ; )

I gotta ask.  Why bother?

I am a faithful disciple of the apostle Paul [Nimz].  Yet verily, he hath
struck fear into my heart.  Paul and I have been talking about installing a
PCV extractor kit on my 92.  Basically it uses a pipe welded into the
cat-back at a 45-degree angle (venturi effect) to draw crankcase fumes into
the exhaust stream.  Crankcase vacuum makes a little HP (thank you, Smokey
Yurick) and safeguards the intake air plumbing from automotive emphyszema.

The question is whether to close off the opening in the front cam cover, to
generate max vacuum.  If so, words like "collapse some seals" test my faith.

Do I just drive around and see if my front and rear crank seals implode?

Ah, once again VO gets to experience the bleeding edge of innovation.
Smokey, where are you when I need you?  Bet he's not answering emails.
