Ford Repair Questions? Ask a Mechanic for Answers ASAP
To clarify, you have a new engine now but the oil light stays on. Did the dealer say that the new engine has damage also or just that the light is stuck on?
So what did they charge you $8k for 6k miles ago?
Oh Ok. I misunderstood. The oil sending unit's only function is to turn the oil light on and off. It might be the reason the oil light is on, but it would have no affect on the way the engine runs or whether the camshaft is damaged.
Have they told you what trouble codes are stored in the computer?
That sounds more like a VVT solenoid than a sending unit.
The problems that we have on all of these 5.4l engines (I have about 250 in my fleet) is either bad VVT solenoids or bad cam phasers. The problem is that bad VVT solenoids cause bad cam phasers which then cause bad timing chains and chain guides.
It could score the cam if the engine was starved for oil, but the only thing that controls oil flow to lubricate the cam journals themselves is the oil pump. The VVT solenoids just allow oil to flow to the cam phasers which then control the ignition timing. They don't actually provide lubrication, just oil pressure operate the phaser.
Please let me know if you need additional info.
