Hi Jason Welcome to FTE

I take it to mean there is now a vacuum leak? That will never do. As you probably know, the distributor needs a source of vacuum for ignition advance at cruise and part throttle. It will run "OK" without it, sort of, and fuel mileage will drop? Your question would best be asked in the 150 forum.
