2017 F150 3.5 ecoboost, 116000 miles. Cam phasers again. Replaced at 31,000 miles, 72,000 miles (New style phasers, timing chain and guides, water pump). Noise is back at 116,000 miles. would an oil additive help.
Cam phasers fix?

Interesting. And I am NOT against the Lucas oil treatment necessarily.
But I'd love to know if just the oil viscosity change might have quieted things down alone?

Yes! Inquiring minds want to know!
Someone with the clatter needs to try either of those.
I absolutely think oil matters. Anecdote- I was using Valvoline Modern Engine Oil, never heard the clatter. Then I couldn't find that oil anymore, switched to regular Valvoline syn... Clattering within a few oil changes.
My truck has never been this quiet after my recent Mobil 1 0W40 oil change.
I don't know how he could?

I don’t miss my 07 Tacoma. It was not trouble free, 4 rear axle seals in 120K a frame that looked like a piece of interior plywood left out in the rain, the brakes with the 1970’s drum in the rear never felt like they wanted to stop the truck like as not very linear in braking force. One front wheel bearing (they aren’t cheap).
I bought a 1995 and it was a beater. But only I ever did was an exhaust manifold. It ran awesome and never failed me .
Do you know if these newer cam phasers will work on a 2014 EB?
I tried a bottle of the Bestline additive and it hasn't made a difference yet.
How dangerous is it to be driving my truck until I get this fixed? I have been driving for some local short trips, but haven't put my camper on or towed my boat.
I have about 120,000 on my truck and want to keep it for at least another 100K.
Thanks

You’re Gen1… likely timing chain stretch. Oil will not solve

Yes, they should work. In fact, I believe Ford calls from them now (assuming the dealer doesn't have a bunch of old style in stock). The newer phasers are half the noise problem. But the new design won't like begin acting up because they work properly. But on your 3.5 there is the timing chain that is likely the other part of your problem. But if fixed, you should ask for the phasers that are more likely last.
As for danger, I've heard of people driving them for a number of years like that. Just sounds awful. But at some point the engine won't be forgiving and it will act up.
According to the dealer and the paperwork, these are the parts put in.
Each time I have gotten updated phasers, this is now the forth style in my truck.
If the noise comes back and I still have the truck, I will put in a heavier oil or additive.
Just dropped the truck off and they verified the phasers they have are the latest version.
It seems like it makes sense to replace the water pump at this time. No extra labor charge by the dealer. Just the parts. Does this make sense?
Thanks

Yes!
Great idea to replace a wear item at only parts cost.

Definitely. On my previous '12, I also had a high flow (don't need higher pressure, which means they take a spring out) oil pump as well. It's all right there and is seems more/better oil flow might help down the road with Gen1 3.5s.
Got the truck back and no rattle!! It's the quietest it's been for a long time. Now I feel comfortable putting the camper on and heading out for a long trip. Hopefully this is the last time I have to do this until I'm over 200K miles.
Thanks to everyone for their feedback!!
