[Healeys] Fwd: New post on my blog

[Bob Spidell]

Michael,

 From your blog post:

"occasionally on overrun very little if any negative pressure was 
evident in the crankcase so, in order to improve things a little I 
installed a plug in the hose which runs from the valve cover to the rear 
air filter and this resulted in a significant improvement"

Probably because you're pulling air (and sump oil) into the crankcase 
through the rear main 'scroll' seal (and dipstick tube and oil filler 
cap hole). This is how the typical, owner-installed PCV installation on 
the 6-cyl cars functions as the PCV valve meters gasses both from the 
crankcase and the valve cover. But ... with fresh, filtered air coming 
in from the carb air filter you essentially had a true PCV 'system,' 
where the gasses--fresh air and blowby--are cycled back into the intake 
manifold to be burned in the cylinders.
