On a healthy engine I would use the set-up that whoflung has used every time, but with a slight mod. I normally use a Cusco catch tank and it can be squeezed in near the ABS stuff to keep the hose runs nice and short. The way it is plumbed means any oil spat out will be caught in the can. And with the hose re-connecting to the inlet means you don't get any engine vapour smells when you stop at traffic lights.

bump, ok, for cleaner exhaust emmisions, which setup i best, vent to atmosphere from catch tank or plumb back to the intake from the catch tank?

Best for the enviroment is back to intake so that the oil vapour and crank case fumes are burnt at a high temp and then delt with via the cat. As for cleaner emmisions, I doubt you would be able to tell the difference. (unless your engine is real tired with very big blow-by and chucking a lot of oil out)
