Engine Help - I'm at a loss
Ford has been our vehicle of choice for 4 generations and may stop after this!
I need help I'll try to be brief.
Last month my 2005 expy 5.4L 108K miles started with all the classic signs of cam-phaser failure (rough idle, stalling, sounds like a diesel). I attempted every fix possible to no avail, I took it to our Ford dealer and they said low oil pressure has caused cylinder wall damage= NEW ENGINE. I bought a re-manned engine from a local shop with upgraded oil pump and ratcheting tentioners to avoid chain slap and new VVT solenoids. I installed it and have the exact same problems. I get a P0012 for bank 1 over retarded. I'm sooo angry that I've spent $4500 and nothing was fixed. I think there is a PCM issue or wiring problem. Please Please help.

Did you go back to those who sold you the engine and installed it? After spending that kind of cash, they should really be willing to help you in finding out what's the cause. Either a sensor issue or an internal issue in the new engine, and I assume that will be covered by the warranty on it.

Then I would suspect the (VCT) Variable Camshaft Timing Oil Control Solenoid. Assuming they swapped your existing one into the new engine. Note, the attachment only shows one, but there is a separate VCT for the left and right sides of the engine. You'll be looking at bank 1 which is the passenger side. You can also swap both of them to see if the problem moves to the driver's side.
