As the timing chain wears, it can change the timing of the camshaft and crankshaft.
Modern engines need to not only know the position of the crankshaft, but the position of the camshafts.
The technology that leads to more fuel efficiency and performance also means increased complexity with timing components.

At cold start-up, the engine rattles loudly for about two seconds. The possible cause could be the variable valve timing control (VTC) actuator is defective. Replace the VTC actuator. This procedure does not require the complete removal of the cam chain and associated parts, so repair time is shorter.
With almost 400,000 3.5L EcoBoost engines on the road today, these engines have proven to be a solid power unit. Many of these engines are out of warranty and heading to your shop. Here are the top failures and what to look for.
