2005 ford f350 automatic 5.4 liter. code p0022 intake camshaft position timing - over retarded (bank 2) . does this mean I just need to advance the timing? When truck gets hot there is a clattering noise. I have been told by a service advisor that it needs to be inspected for damage to the cam bearings and if so i will need new cylinder head(s).
The possible causes could be the following:
1. Camshaft timing improperly set
2. Continuous oil flow to the VCT (variable cam timing) piston chamber
3. VCT solenoid valve stuck open
4. Camshaft advance mechanism binding (VCT unit)
It's probably a good idea to have the cam bearing checked, especially if you are hearing noise. There is a possibility that the head would need to be replaced if new bearings won't fix the problem.
Is this vehicle still under warranty? I would make sure that the place you're taking it knows what they're doing, this can become costly. Don't be afraid to get a second opinion either.
Hope this helps.
