Re: power boost internal leak?

Maybe ----- If you remove and plug the vaccuum source line and operate without the booster you can see if problem still comes and goes. If still comes and goes with no external leaks I would suspect the mc. If problem removed I would suspect the booster. Be careful where you test this as you will be removing the power brakes and will take more effort. May be an easier/better way tho.
