Ford F-250 SD knocking problems

Filed Nov 4, 2026 · Engine · AZ

I have a 2021 Ford F250, the truck was bought new has 34,467 miles on .Oil changes every 5000 miles. Was returning home from camping and engine developed a miss, engine light came on,I was able to make it home and engine developed a loud ticking noise in the upper part of the engine. Truck was towed to a Ford dealer ,where it sits for the past 2 weeks ,waiting on Ford to decide what they are going to do with it. Dealer told me ,after a tear down ,that Ford wanted ,that it was the cam and lifters. This is a known problem ,and Ford dropped the ball on a recall on this engine. Besides the cam ,lifter issue ,there is an oil pump problem with this year engine. I bought the truck as a retirement gift to myself, and now appears to be the worse decision I've made. I believe Ford needs to replace the engine and not just fix the cam and lifters as small metal particles will be through out the engine due to the above failures and will cause a failure again.

I am hearing knocking (metal on metal) noise at idle. I am concerned it is the cam and lifter oil starvation issue. Also, the idle has become a bit rough with intermittent misses causing vibration. I took to the dealer and they said this is "normal function". while the engine is running, there is no safety risk. but when/if the lifter/cam fails, the truck will lose power completely and, depending on where this occurs, could be quite dangerous.

Mechanical Failure Description: The vehicle suffered a sudden, severe engine knock and rattling under load at approximately 87,594 miles due to a catastrophic valvetrain failure. Dealership diagnostics at Randall Ford confirmed a loss of compression on cylinder 4 and extensive metal shaving contamination throughout the engine oil filter assembly. This severe internal damage resulted from an apparent mechanical failure of the hydraulic lifters and camshaft lobes, requiring a mandatory and complete replacement of the longblock engine assembly. This failure mirrors the exact lubrication and valvetrain degradation mechanisms currently being evaluated under active the federal safety agency Defect Petition DP26011, demonstrating that the structural defect impacts the initial 2020 model year production run of the 7.3L Godzilla platform.

I am writing to report a potential safety defect on my 2022 Ford F-250 Super Duty. Since purchasing the vehicle new, the hole in the towing receiver where the pin inserts has ovaled out while towing. On a recent drive, this caused the hitch pin to shift, knocking out the cotter pin that secures it. This created a dangerous situation where the trailer could have disconnected. I contacted the dealership, Ford Country at 280 N Gibson Rd Henderson nv 89014 but they stated this is not covered under warranty. My Vehicle is still under the 3yr 36k warranty and i have the extended 6yr coverage. I believe this is a manufacturing or design defect that could affect other F-250 owners who tow. Please investigate this issue for the safety of all drivers on the road. Thank you,

The failed component is a lifter/camshaft. Luckily I was attentive to my vehicle and noticed a ticking noise within the engine and took it to a dealer for diagnosis. An engine failure while traveling at highway speeds could be a disastrous to occupants and others around them. This appears to be a common problem with the 7.3l engine. The check engine light illuminated after i noticed the ticking noise.

Engine making heavy ticking noise from front of engine because of a cracked oil pump gear and the front main seal is now weeping oil. Ford is aware of this known issue as a TSB. Afraid to drive truck because I normally haul a large travel trailer into the mountains and the technician said the oil pressure could drop causing the motor to seize up.
