To check for a leak at the gasket, turn the engine on and let it idle. Then, use a piece of cardboard or paper to block off the opening around the intake manifold. If the engine’s idle changes, it’s an indication that there’s a leak in that area.

Once you’ve located the source of the leak, it can be repaired with a sealant or, in the case of a damaged hose, replaced.
