crank case ventilation

[Tony Z]

Guys, my mind has been wandering again and I thought of something, but want to know your opinions on it.

The general idea with crank case breathing is to have a central box that recieves the extra pressure / oil from the rocker cover, as well as vents the case from the stock vent and / or from the fuel pump location. This box possibly vents to atmosphere or to the carbs.

what about this?

Use the box as above, but instead of venting the valve covers to the box, run them direct to the sump - easier if you have a deep sump. that way, any extra oil in the covers will drain direct to the sump. also, if you go thru a long sweeping bend, you wont have a problem with the oil collecting in the cover, it will drain direct to the sump. you could then also run a "scavenging" system to the breather box that sucks a bit of a vacuum in the cranksace and not worry about sucking oil from the valve covers and spilling it all over the tarmac. The easiest way of having this type of vacuum is to create a venturi effect in the exhaust pipe.

blah blah blah, you get the idea, I am just starting to ramble now.
