My 7.3 is Cooked - Lifters

Yes, 4 guys. OP has 2020. My point exactly. Are lifter failures trending on 2026 7.3Ls? Should we still be concerned in 2027? I think not.

I mean, who knows. I doubt there too many 2026 trucks with the miles required to have an issue. The CP4 is supposed to be fixed in the newer model 6.7’s as well, but I’m definitely not taking Fords word for it. They don’t have the track record of honestly for that.

OK, include 2025 7.3L's, anyone here experience or have info from elsewhere showing that maintained 2025-2027 Godzilla 7.3L's still trend high rates of lifter failure after Ford resolved the early 2020-2023/24 era delamination or low oil pressure issues?

It's obviously a moving scale based on build date. Older trucks with more miles are gonna have the highest failure rates. It ain't gonna happen to a new truck with no miles. Which is why '23+ trucks are just starting to show failures. How many '25+ trucks do you actually think have enough miles to start showing cam/lifter issues already? My '24 only has 13k on it. I f'n hope not but in a few years it could be '25-'27s doing the same thing as more and more of them start getting miles on them. I certainly don't trust the engineers and bean counters to fix anything.

There are lots of 2025 work trucks with plenty of miles on them.

I've watched a lot of videos that cite only 8psi at idle as the biggest problem. What's your source for the 20-22psi stat?

Ford 7.3 Godzilla Oil Pressure Gauge Installed, Results are in

Cold start the pressure jumps to over 60 psi than drops to 28-30 psi at 1200 RPMs than after motor is fully warmed up the oil pressure at 600 RPMs drops to 18-20 psi. This was only a idle warm up test not driving, will be doing that in about a week. However testing at different RPMs after warm...

Again, if oil pressure alone was the problem, nearly all 7.3's would be blowing up, especially work trucks that idle all day long. There clearly is more to it than that.
