cam phaser problem

You can't simply put a different engine in there. You have a computer operating system that is engineered for one engine and one engine only, not to mention it would be against federal law to attempt that anyway.

That system is highly dependent on oil condition and viscosity so if you have been lax with oil changes and oil type you will have problems. I would suggest changing the oil using a high quality 5W20 oil.

It does get oil changes at every 30000 mobile1 5w-20w with a motercraft filter especially since 3 months after I bought it I had to have it done so if motor blows I cant replace it because it would be against federal law? Was looking at changing to newer model year motor that didn't have the same problems with cam phasers and that I didn't have to replace the trans. or wiring or computer the phaser problem was mainly in 04 and 05 models and it is very common in those years transition years that's why they have the heritage version in 04 to was looking at still 5.4 but newer version when they updated the problems

There is no oil in the world that can be left in an engine for 30,000 miles.

You can put another engine in your car, it just has to be the exact same one. Forget the illegal part for a second. No other engine will work under that operating system. It is engineered for that engine and that engine only.

how do you change a phaser kit on a 5.4 triton 2004 f-150

The procedures are as shown in the diagrams.

In july I was in a head on collision. The engine light came on today. I took it to Ford dealership to have it looked at. They said, besides needing a tune up, that the cam phasers need to be replaced. Could the wreck have caused this problem?

No not necessarily, how much damage did you do on front end
