With 83,000 miles, we checked the oil to discover it was empty. Upon taking it to the dealer, they determined that there was severe scoring due to the known pcv value issue under TSB 19-2365 for excessive oil consumption. Prior to this time, there had been no oil issues with the vehicle. Dealer recommended replacement of the engine. The engine was replaced in August 2024 with a remanufactured engine. The oil was changed on December 5, 2024. From that point to February 25, 2025, the oil was checked periodically with 3 quarts of oil being added over that period of time. We took the truck back to the dealer to check to see why there is excessive oil consumption again. The dealer instructed us that they would need to follow the recommended action in TSB 19-2365 to reprogram the powertrain control module, install a new engine oil level indicator, and change the engine oil. We would then need to bring the truck in weekly for the dealer to check the oil to assess whether there was excessive consumption of oil. We asked why the engine would have been replaced in August 2024 with another engine that had the same problem as the engine replaced. Weren't the corrections done to the engine per the TSB 19-2365? we were told they did not know.

Purchased Dec 4, 2019; followed maintenance requirements through bo beukcman quality Ford. Oil changes made iaw Ford guidelines every 5000 miles. Oil change was made Nov 23, 2023 at 49,504 miles. Just before next oil change noticed engine knocking on acceleration/deceleration with intermittent check engine light on. Oil changed at 54,226 miles (Aug 22, 2024). Condition mentioned to dealer. Dealer advised engine was consuming oil. There was no visible sign of leaks. Fix -- install new dip stick, reprogram the powertrain control module (pcm). Rationale: Ford TSB 19-2365 Dec 5, 2019 quoted as follows: oil consumption "may be due to high intake manifold vacuum during some deceleration fuel shut off (dfso) events resulting in oil being pulled into the combustion chamber from the crankcase, valve guides and positive crankcase ventilation (pcv)". Supposedly reprogramming would reduce engine vacuum during dfso events (note: I noticed knocking on acceleration). At the dealership inquired why Ford did not advise customers of condition. They could not answer my question. My F-150 is a 5. 0l v8 and was described by dealer as a coyote engine. I asked if they had similar maintenance events like mine; answer - yes. I was disappointed; have owned previous F-150s and none "consumed" oil like this -- my previous truck had 150,000+ miles -- no oil burning. The dealer instructed me to bring the vehicle back every 1000 miles to check dipstick for consumption. Returned vehicle to dealer at 55,626 and 56,700 miles. On returns, consumption was noted; they topped off my oil with instruction to return again at 57,626 (current mileage 57,435 miles) this is inconvenient and poses a safety risk to me and perhaps others through engine degradation/failure especially while driving. Believe Ford owes the cunsumer a permanent engine fix. Vehicle is available for inspection NHTSA.

The contact owns a 2018 Ford F-150. The contact stated that while driving at an undisclosed speed, the oil pressure warning light illuminated. The vehicle then made an abnormal sound. The vehicle was towed to an independent mechanic, who diagnosed that the oil plug had detached, causing all of the engine oil to leak. The mechanic added oil to the engine; however, the check engine warning light illuminated while driving. The vehicle was taken back to the independent mechanic, but the check engine warning light was no longer illuminated. The independent mechanic determined that the crankcase ventilation system had disconnected; however, no repair was performed. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 64,000.

2019 F-150 vehicle is equipped with a 5. 0l engine that exhibit excessive oil consumption, to where every month I have to add oil. There are no visible oil leaks. Each time I go for oil change before the 3 months and/or recommended 3,000 miles, im told there is no oil in the engine. After doing research, I found that the issue of excessive oil consumption is caused by high intake manifold vacuum during some deceleration fuel shut off events resulting in oil being pulled into the combustion chamber from the crankcase, valve guides, and positive crankcase ventilation (pcv). To correct the condition, steps to reprogram the powertrain control module (pcm), installation of a new engine oil level indicator and change the engine oil and oil filter. The revised pcm calibration reduces engine vacuum during some dfso events. After calling local Ford service center, the issue was confirmed and I was told that there isn't a fix for the problem. I was provided by the Ford service agent the contact information for Fords customer service. Spoke to the agent who told me that there is only a recall for the tailgate for my model. Anything else I would be responsible for repairs. The Ford customer service agent then gave me the website to NHTSA to file a complaint. Now I'm doing just that. It appears that this is a common issue for my year make and model. Please investigate, please help.

I purchased the truck early 2021. After about 6500 miles, upon starting the vehicle a warning message to the effect of "oil level low, add oil" appeared. After manually checking my oil dipstick, I found the oil level to be below the safe oil line. I promptly took the truck to the Ford dealership in which I purchased it. The service technician informed me of one other case he has personally experienced where the pcv system was defective, allowing an excessive amount of oil to be consumed. Ford was unable to receive my vehicle for service for 1-2 weeks due to a full service schedule. It was at this point I attempted to go to a 3rd party vendor for an oil change. That vendor checked my oil level and confirmed the reading was below the safe oil line. They advised I return to Ford. Concern for my safety and the continued safe operation of the vehicle, I requested the 3rd party vendor to add a quart of oil. In the end, it took 2 quarts of oil to return the oil level to a safe operating zone. I then promptly returned to Ford and spoke to the service department manager. They will accomplish and oil change and return the vehicle to me to perform an oil consumption test over the course of approximately 1,000-1,500 miles, before returning to Ford for further evaluation.

I have 22,500 miles on this 2017 Ford f150 3. 5 ecoboost. It has started throwing a code of po4db crankcase disconnect. I have been researching and there are a lot of Ford products having the same issue. This code make engine light come on and stay on. It appears it's in the computer system, is my understanding. Sitting still, driving it doesn't matter engine light stays on.

Upon cold start vehicle blows blueish/white smoke for approximately 6-8 seconds then stops. Does not smoke while driving and vehicle runs just fine otherwise. Took to dealership and they said it was a pcv valve stuck open and they relaced it. . . . . That didn't fix the problem.

2016 f150 with the 2. 7l ecoboost randomly dies after startup. Sometimes it will die while in motion almost causing an accident. There's no stored codes for the dealer. It's been in the shop 6 times total. The first time they put a crankcase vent sensor and then the 2nd time sparkplugs. It's dies and gone into limp mode multiple times but the dealer can't duplicate the problem so they can't fix it. It started at 9,000 miles and it now has 14,000 miles. I'm pretty sure it's the throttle body but they won't replace it without a code. It has happened randomly from March 2017 until today 8-13-17. I also have a recording saved on my snap-on scan tool of the parameters at the time it went into limp mode.

Head gasket failed on my 1997 Ford F-150 with 4. 2 liter (v6) engine. It leaked into crankcase and the engine locked up. It is a total loss of the engine and I can't afford to buy another engine. I have found out that this has happened to many other people.

Gasket leaked water into crankcase of my 97 Ford f150 with a 4. 2 engine. Had to replace the engine for a little more than $4000. 00. Ford knows of problem but will not compensate cost. There are a lot of angry Ford owners out there with the same problem. My Ford truck had only 68000 miles on it.

I have a 1997 Ford F-150, with a 4. 2 liter engine, and 82,000 miles on the vehicle. For the past few years I noticed a gradual decrease in the coolant level, however, I could not determine where the leak was occurring. Also, for the last three weeks leading up to the occurrence, I noticed the engine would knock when I would start it up. In October of 2004, after starting the truck, I saw white exhaust smoke and heard the #1 piston rattling. I have since found out that this is a common occurrence with owners of '96 thru '98 model Ford cars and trucks, with 3. 8l and 4. 2l engines. I have also seen Ford TSB's that prove they have known for about six years, that the front cover gaskets have a high incidence of failure, causing coolant to leak into the crankcase. Also, that the intake manifold gaskets can fail, which causes coolant to leak into the #1 cylinder. When an engine is started with water in the cylinder, the piston rod is likely to bed or break. The manifold gasket failure is responsible for my problem, as well as that of many other Ford owners. The remedy for the problem is an engine replacement, costing about $4,000. Ford motor company is not taking responsibility for this engineering defect, leaving many unsatisfied customers to pay for their faulty engines. I have not had my engine replaced yet.

I own a 1997 Ford F-150 truck, 4. 2l v-6. My wife was driving the truck and with no warning the engine started knocking very badly, she was frightened and drove the truck home very slowly, which almost got her into an accident. After doing research with Ford mechanics and private mechanics, I found out the engine is a defective engine the years were 1997 and 1998. I contacted Ford and they will not stand behind their product. There customer service in detroit was no help at all. I bought the truck with 36,000 miles on it, took very good care of it, and it now has 64,000 miles on it and cannot be driven. I recently received a recall for the cruise control saying it could catch on fire. Unfortunately the truck can't be moved until I replace the engine, and it is in my garage. If this truck catches on fire and burns my house down Ford will be sued. There was no warning when the engine went, failure was total loss of engine, again Ford has done nothing.

Incident = in 2000 Ford motor company extended the warranty on Ford F-150 pickups to cover a known design problem involving a gasket that kept coolant fluids from leaking into the crankcase and destroying the engine. They only offered to replace the existing gasket to make sure it wasn't leaking and then extend the warranty for another 12 months. Just as they knew it would, approximately three years later (April 27) their replacement gasket cracked and coolant fluid leaked into the engine through the crankcase, and my engine seized up. Damage resulting = my engine began to clatter, and I drove straight to a dealership. I am now having to replace the engine ($3,600. 00 plus tax). In talking with the authorized repair dealer in clarksville, TN where the truck broke down and my usual authorized repair dealer here in nashville, apparently this is happening to many of the F-150's that received a new gasket and an extended 12 month warranty. Again, Ford knew there was a design problem (which by the way both places told me Ford corrected in subsequent years) and only offered a band-aid approach to dealing with it. In talking with the Ford motor company consumer affairs, I have request that the cost, or at least a portion of the costs, of my new engine be paid by Ford. The repairs will be made tomorrow, April 29. Needless to say, Ford has not responded or offered to pay for my new engine.
