IIWMI'd run the engine & get the coach level, then shut it off & listen for air leaking. If I can't hear it leak on level ground, the air leak is slow enough there won't be an issue driving. It'll be a nuisance on occasion, but maybe an R&R w/cleaning and good inspection of the tubing ends will find the problem.
