Where do you put silicone when replacing intake manifold gasket on 1994 5.7?

When replacing the intake manifold gasket on a 1994 5.7 engine, apply silicone sealant to the corners of the intake manifold where it meets the cylinder heads, as well as along the front and rear of the intake manifold. It's also recommended to use a thin bead of silicone in the areas where the gasket will be seated to ensure a proper seal. Avoid applying silicone on the entire gasket surface, as it can cause leaks. Allow the silicone to cure as per the manufacturer's instructions before starting the engine.
