The PCV valve was the greatest invention the environmental movement spawned.
The blow by vapors stink! You ever get a good whiff, you will understand.

I would think a T in the line going to the brake booster, would allow you to connect the PCV valve. You might add a vacuum canister with a check valve in front of it to make sure the brakes have plenty of reserves, if it doesn't have that already. Verify I am not full of it, because brakes are more important! Use my idea at your own risk. I do not know everything and comment freely to inspire thought. It is not advice.
