How to Remove an Intake Manifold Gasket
Because the intake manifold gasket is exposed to extreme temperatures when the engine is running, it can begin to crack and deteriorate over time. When this happens, it will begin to allow fluids to leak out of the engine, creating serious problems. Removing the intake manifold gasket to replace the part is a job that can be done in about three to four hours. You can save time and money by doing the work yourself.
