That’s not a cam phaser issue. You are low on oil. The rattling you are hearing is no oil to the top of the motor. Not good. These things burn oil. A lot of oil. Mine burns about a quart every 1000 miles. Check the oil level just after start up. If it’s not in the grades area you are a quart low. If it’s not on the stick you are more that two quarts low. Ford has done a good job of covering up this issue. They claim that a quart every thousand miles is within normal usage? That a joke. These trucks will give you no indication of low oil until it’s too late. I know because I’m on my second motor and the new motor I installed has the same issue. You have to be diligent about about checking it. If you drive hard, use sport mode and downshift a lot, these are all factors in the oil consumption. The other thing I would recommend is to set your dash with the oil pressure gauge. Check the gauge at idol with the right amount of oil in it. It should be close to 10psi at idol. That will start to drop as you burn oil. Keep an eye on it. BTW the dealers know there is a oil consumption issue with The 3.5 HP. They will play dumb and do all there stupid software flashing blah, blah,blah. Try to find a good dealer that will own up to the issues hand help you out. Good luck
That is a ton of incorrect and inaccurate information. It is not normal for these trucks to burn oil. There was an oil consumption issue on earlier builds that was caused by the PCV system in the valve covers, that was corrected by valve cover replacement per the TSB. There is no “issue being covered up” despite your ridiculous conspiracy theories.
The maximum oil consumption spec is 1 quart per 3k miles. Most burn no oil, including mine.
Oil pressure does not change with oil level, that’s completely wrong. If the oil level is between the minimum and maximum spec, the oil pressure will be consistent. It will not vary based on level. If the oil becomes low enough to starve the sump, pressure will drop to zero.
If your oil pressure is 10PSI at idle and drops from there, you have engine damage. Typical engine oil pressure at idle is ~20PSI.
