The O rings were bad on mine and caused it. You can lose a set of rings by letting the problem go and O rings aren't that much and you can change them in a couple of hours. Your sucking in air from somewhere thats not metered and thats the likely place. They get old, brittle and hard over time and don't seal well so you might as well try them.
