I own a 2007 Passat that has been sounding like a diesel since April 2011. Nothing was found until a signal to Stop Engine low oil pressure light came on. After dealership dropped oil pan (particles in oil) and inspected cylinder heads, the engine has been said to be in good condition. When the vehicle was started after tear-down and oil change, the loud sound led to the cam adjuster. Originally, the metal particles and the initial diagnostic led to the assumption that the entire engine would need to be replaced.
It has been explained that this is unusual for a Passat at 84,000 miles. I am looking for input on the reliability of the engine after cam adjuster failure and if other failures can be anticipated after this unusual failure.
Thank you for your input.
