What to do if you have an intake manifold leak?

Go see a mechanic to have them verify if it is this gasket or not. A mechanic will be able to perform a smoke test to rule out vacuum leaks. A smoke test injects smoke into the intake system. If there is a leak in the system, smoke will come out from an area it’s not supposed to.
