| − | There are several methods for locating vacuum leaks. Occasionally, you may experience a vacuum leak into the intake ports from the crankcase of the motor due to the intake manifold / cylinder head interface not being machined parallel. No amount of propane or carburetor cleaner will find such a leak. The best way is to insure the elimination of such a problem while building the motor. See the wiki article: [[Manifold/Head vacuum leak, internal]].

| − | Fixing a leak. My old neighbor built circle track cars and after the ran the engine he would shut it off...tape off every opening with duct tape then put a hose over the dip stick and hook up to a vacuum source. He would then get his stethascope and listen in the area where the propane or carb fluid indicated a leak. he used Rtv and calked into the area until the stethascope whistle stopped. too much vacuum will pull too much calk into the hole.
