1999 Chevrolet Venture - Intake Manifold Gasket

Leaking Intake Manifold Gasket Symptoms

The intake manifold gasket provides an air-tight seal against the cylinder heads to prevent any leaks from the fuel and air mixture as it is distributed between the heads and the intake manifold. Some vehicles also use their intake manifold to house the thermostat or perform other cooling system functions, and if that is the case, your intake manifold gasket may also separate and seal the coolant channel. Over time or due to high engine temperatures, the intake manifold gasket on your vehicle can suffer damage and begin to leak. If the intake manifold gasket has deteriorated enough to allow leaks, it can allow excessive air to enter the engine and result in a lean condition that can affect performance and efficiency. You may notice a rough-running engine, misfires, a decrease in fuel economy, and even coolant leaks or overheating if your intake has a dedicated coolant channel. A leak from the intake manifold gasket may also activate the Check Engine light, and O'Reilly Auto Parts offers free Check Engine light testing to help you begin your diagnosis. If you need a new intake manifold gasket for your repair, O'Reilly Auto Parts carries replacement intake manifold gaskets for your vehicle to help you make your repair and keep your engine running at its best.
