Cam Phaser Repair Fail

Here is a TSB video by FORD BOSS ME that is interesting as well:

This 'fix' has been discussed ad nauseum. Doesn't always work. In my case, sometimes when I do this I hear them clanking as the starter cycles, it actually sounds worse than the actual startup rattle.

Dealer just let me know the new solenoids din't fix it so now a Ford engineer will be there tomorrow to determine next steps.

Way to be an over-achiever!

Damn bro, looks like your getting free mileage. But it’s going to be in that basic F-150 loaner. Hopefully the engineer can get things rolling.

I wonder if this guy has come up with the first preventive action for our Cam Phaser issues, until FOMOCO comes up with a better fix?

Attempting to prime the oil system before starting will not prevent or fix anything. All that does is mask a failure that has already occurred. The phasers are designed to lock after shutdown. If they don’t lock properly, you’ll get a rattle on the next cold start until oil pressure fills the phaser cavities. Priming the oil system fills the phasers before starting, which masks the noise but does not correct the failed locking mechanism.

Correct, it does not prevent the locking pins in the phasers from failing nor does it fix them but it keeps the phasers from beating the hell out of themselves until they get oil pressure.....

FordTechOne,
Thanks for commenting. I do pay attention to your posts as they contain great content.
Within your post you mention “failed locking mechanisms“ and “… mask a failure that has already occurred “. Thus, I have this question:

If one owns an 3.5 EcoBoost engine that has yet to reveal signs/symptoms of cam phaser issues, would it be advisable to prime the oiling system prior to startup?
If not, why not?

I understand if an engine has such issues the damage is done…
I’m not a Ford certified mechanic, but I find the technicals of our engines very interesting. I hope you could explain the process of why it would or would not help on an engine that has yet to showcase cam phaser issues.

If there is a way to prevent a cam phaser issue, I’d like to.

Thanks in advance.

Priming the oil system will not prevent the issue, as phaser pin wear/failure occurs during VCT operation and engine shutdown.

When the system is operating properly, the phasers remain locked until there is sufficient oil pressure to unseat the locking pin. Whether that occurs during priming or after engine startup does not change the functionality.

Well, lets hope they get this resolved soon, darn. Maybe they can upgrade your truck (loaner) for you, at least for your trip, seems like a no-brainer.
