[Diy_efi] Venturi effect crankcase breather

[Matt Porritt]

To put it simply for you:
'A' (ANY non force fed engine) 'sucks' on its inlet stroke right?
If into the inlet tract there is 2 paths to atmosphere (ie simple Y pipe)
then when the engine 'sucks' on its inlet stroke they will both have 'suck'
on them right?

If you put the crankcase breather one of these parts its gets 'suck' on it
also!
Not quite magic, but a vacuum gauge easily shows there is vacuum.

At idle it will register quite high actually

No I'm not suggesting car engines have completely different sets of dynamics
from car engines...????
