The Ford 4.6-litre engine is a modular unit that is part of Ford's of V-8 and V-10 engines equipped with overhead camshafts. It can develop manifold problems that can negatively affect the engine's performance. You can save money by repairing the manifold in your driveway or garage and avoiding a trip to a mechanic.

Heat Damage

Excessive engine heat can cause the plastic intake manifold installed in the Ford 4.6-litre engine to break or fall apart. Replace the plastic manifold with a metal manifold, which can tolerate higher stress levels and temperatures.

Gasket Leak

Popping noises during engine operation can indicate a leaking intake manifold gasket, caused by expansion and contraction of the gasket during engine start-ups. Inspect the gasket for wear or broken material and replace it to stop the leak.

Stuck Intake Manifold Runner Control

Corrosion or sediment build-up on the lower intake manifold plates in a Ford 4.6-litre engine can cause the intake manifold runner control--or pipe that connects the cylinder head and throttle body that allows air from the intake valve to flow into the cylinder--to stick or remain open during engine operation. Check the plates for sludge or dirt and clean them thoroughly to restore normal function.
