Could this be why my rear main keeps leaking?
The oil actually gets thinner because it is diluted with fuel. PCV enables less frequent oil changes. (Oil filter was an accessory on early Holdens, which helps also.) They just had a vent on top of the rocker cover to let fresh air in before PCV.
I can scan the manual and email it if you like.
