Unfortunately, we would have no way of knowing what oil filter came off the vehicle. The PZ42 was the correct application for this vehicle. I made a typo in the title and incorrectly listed the engine size as a 5.5L, my mistake. It was a 5.4L.

The mechanic at the ford dealer told the owner the oil filter caused the engine failure. The filter was tested and found to be 100%. What internal part could have caused rubber inside the engine?
