I use 1, from the rocker cover to a Toyota PCV valve into the manifold, on both my 1360 and 1412 stroker.
I had it on the flywheel housing instead, but the drop gears tossed oil up it on long LH bends if I had `a few' revs up.

IMO you only need more than 1 decent breather if you have poor ring sealing. :wink:

I don't like catch tanks on road cars, they make the cabin smelly. But yeah if it was a racer I'd use one.

On my 1360 (now back in the car) I have since added a hose from the rocker cover to the drop gear housing- to help equalize pressure upstairs/downstairs.

That's awesome.

I have a single breather, basically the same setup as the good Doctor's. Seems to work well enough.
