Cam Facers- My ford expedition had the cam facers go out, When the vehicle needed to be repaired I took it to 3 different shops, The advanced issue never was addressed. So I called coyote engines and they recommended a engine rebuild from the ground up and they fixed the problem. The check engine light has not come back on since. Its been 5000 mile now . If you need a mechanic to fix your engine these mechanics at coyote engines did a fantastic job for me.
