Need help PLEASE!!

I just purchased a 05 F150 5.4l 3V 122k miles seen the valve covers had been off because I could see the silicone and dealer told me the cam phasers and timing chain was replaced. Shortly after the purchase it started to miss or rough idle as soon as I started it. I had the plugs and coils replaced (with motorcraft) and it was running the same as it was before the mechanic said it was throwing the P0300 code multi cyl misfire. I was advised to take it to the dealer for a 150$ diagnostic. I took it to the dealer and was told ignition was good, compression was good, and the injectors were good, tech said he monitored the pids and had whole left bank misfire and found VCTADV error on bank 1. He recommend VCT phasers and timing chain tensioners... 17hrs of labor!! Now I took it to a local ford master mechanic and am being told that the motor is ruined and it needs a new one @ $4800. Mechanic stated that if these motors get low oil pressure then they are ruined?? Any ideas or help? Truck runs great other than the miss it seems to be real quiet to! Thanks in advance

How long have you owned it and did you not get any warranty, even a short one with it?

I am having the same problem, no one seems to have an answer. My vehicle runs very smooth until it heats up, then the problems start, lacks power, noise, and unstable idle.

First you need to check the crankshaft endplay. There have been issues with the thrust bearing wearing wearing out allowing the crank to walk. It is mostly on 2007 engines but check it anyway to make sure. Then check the oil pressure at hot idle with a mechanical gauge. The dash gauge is not accurate. You should have at least 20 psi oil pressure. If both of those are good then you can try the updated VCT solenoids in my signature. They have been updated to help with the noise.
