Re: Breather help
Crankcase pressure is created by combustion gases getting past the rings.
Carb doesn’t create vacuum, it controls it. For the hose to collapse you’d need way more vacuum than the motor creates. It’s a long ways from that breather hose on into the motor on one valve cover, thru the motor to the pcv valve on the other cover. |

Re: Breather help
Would using the metal tube like this pic shows, get you the added inch you need due to the spacer?

Re: Breather help
For that hose to collapse from vacuum you'd have to have one seriously dirty air filter.
