FORD 7.3L Godzilla Camshaft and Lifters Delaminating

Hearing this on other forums and YouTube videos about 2020 thru 2022 Ford 7.3 gas motors having issues with lifters failing.

Wondering if any Ford 7.3 owners having any issues

If so post how many miles.

Was also thinking changing oils to Mobile One full synthetic vs Fords synthetic blend,

My 1st oil change and all oil changes since I have used Mobile One full synthetic oil, could this help any valve lifter issue from failure, just a thought.

I also changed my oil at 7000 miles but maybe upping it to 5000 miles

If youíre seeing cam failures start adding a zinc additive the oil.

No issues I know of yet just trying to avoid any issues with Fords new lifter issues.

From what I understand its the lifters that has issues and it damages the cam, would zinc help there as well.

Would like to know how many 7.3 are having these issues.

To the best of my knowledge, no one here has reported an issue.

My 2020 chassis with 10k miles is doing great. I will be doing an oil analysis when I do the next oil change just to see if anything funny is showing up

Oil has changed a few times ,, dont quote my time lines.. but the zinc and other additive took another drop in 2007-2008 and again .... i think 2 times to current standards.. Many additives hard the CATs and also claimed to poison the air/environment.. plus lower viscosity for fuel mpg..

At the same the industry has been building engines with better materials and tighter tolerances that work better with these new oils.. ..

Another thing many of us overlook is these motors LAST..miles and miles..

late 60's, 70's , my beginning as a motorhead.. 60-80K was normal for a valvejob and bearing ,,, timing chain.. The later 80s-90 many newer motors started seeing that 100K... lttle foriegn motors pulling 120-140k only limited by the rubberband timing belts.

Todays norm is buying 100-120K car/motor is no big deal.. 180-200K is not unheard of...

So the oils do work, the new motors work..

Sure a few design hicups and manufacturing oddities....

Had a guy with a 3 year old F150 tell me he just got his new coyete motor.. used i qt oil every 800-1000 miles since new,, at 23K he finally got it replaced... been perfect... OOPS..

Many manufactures have changed oil change intervals from those 7500-10k-13k back to 3500- 5000-7500 ranges max many times as that seems a norm..
Vehicle use is a big factor..

The sky is falling down. We've got to tell the king!

Zinc, various oil additives and oil brands themselves are not going to cure a design or manufacturing deficiency. It may put if off a while, if it truly exists. Where do you guys drag this out from?

STOP giving advice that youíre mis-informed about. Zink does not help lubrication, it is used to help harden the lobes and lifter surfaces of a new flat-tappet cam during break-in while they are establishing a wear pattern. Zink causes the pressure and sliding friction to slightly modify the metallurgy during break in. Thatís it. No effect at all for rollers rolling over a surface.

Yep they have a metallurgy problem with the parts. No oil additive will help with that for very long if at all. Especially not zink,

I agree that zinc will not stop the roller lifter problems Ford and other manufacturers are having, but not your statement of what zinc does. ZDDP (zinc) does in fact create an anti friction film on metal.

You really should back that statement up. It doesn’t change metal. It is simply a cushion for dry starts. First it was the lead, and we had to have better valves and seats, then it was the sulfur. Then it was zinc in our oil, (which if your car burns, get it fixed)

" Most modern motor oils conforming to the latest API SN and ILSAC GF-5 standards (typically identified with a starburst symbol on the bottle) have significantly reduced ZDDP content because it degrades catalytic-converter efficiency, and unlike old-school flat-tappets, today's production cars use lower-friction roller cams and tappets that don't really need ZDDP to live."
