Published by Dustin Babich on

The rough side of an intake gasket goes up. When installing a new intake gasket, it’s important to know which side should face up.

The rough side of the gasket should be facing up towards the intake manifold, while the smoother side should be facing down towards the engine block. This ensures that the gasket creates a good seal between the intake manifold and the engine block, preventing any air or coolant leaks.

It’s also important to ensure that the intake manifold bolts are tightened to the manufacturer’s specifications to avoid any potential issues. Installing an intake gasket properly can prevent costly engine repairs and keep your vehicle running smoothly.
