You know, the service procedure just says to flash the latest PCM calibration file with FDRS/IDS. Maybe the newest file just includes the "fixed" oil pressure table? Which would mean we could "perform the recall" with Forscan...

 

There are F550 ambulances. I've seen a 4x4 version.

 

Aside from software--which I would love to minimize on my truck--this seems like a reasonable way to adjust oil pressure to avoid a certain problem. Of course, sometimes you can over compensate, adding complexity, to avoid a certain problem that may not really present a risk for most people.

 

Called the dealership’s service writer back today as he instructed me to. To check if my 7/22 built 7.3 was added to the “ Customer Satisfaction Program 24B27” effective VIN list and it is not. He said it must already have the updated program for the oil pump. He said if it ever needs updates a notification will pop up on the screen in the truck.

 

The only way to know for sure is to somehow connect a real oil pressure gauge.

 

My May '23 Kentucky build F350 does not show up for this CSP on the Ford site when I put in my VIN. I don't know why this CSP is so selective, they all have the same pump and factory software, correct?

 

No one shows up on the VIN list on the wedsite.

 

I have a 2020 built in may 2020. I was in the Prince George ford friday and spoke to the service manager. They are top superduty dealer in Canada. He checked and mine doesnt get the update. He said not all trucks are included, some are some arent. I said I dont get it but he reassured me? I have extended warranty unitil 2027.

 

There is a video on you tube where someone checked it with a mechanical guage. Operating temp it was 22-23 at idle.

I haven't seen anyone either sijnce this post first started.

 

I just installed a Glowshift oil pressure gauge in my truck this weekend and the 22-23 psi is exactly where it is hot.

 

Dam that initial cold startup sounds like it has cam phaser or lifter rattle.

 

Generally, 10 psi per 1k RPM is good oil pressure for an engine. Cold will be a bit more, but it's a good average.

 

For those who have had failure in the first few thousand miles it is most likely a metal defect. Unfortunately the attention to detail at suppliers and quality is not consistent in modern times. The company that produces camshafts for Ford can get a bad run of blanks. Another company may supply the lifters. I don't know. The initial break in period is most critical for a camshaft. I would think Ford test runs these engines in before installation.

If your motor has lasted thousands of miles you are probably good from a metalurgy standpoint. The ones that fail after that maybe it has to do with maintenance intervals. I never go past 5k before changing oil even with synthetic as I don't believe 8000 or 10,000 miles between oil changes is good for the motor and don't buy cheap brands of oil and filters (supertech) and don't take it to quick oil change places.

I have 77,000 on my motor and counting. If it fails I will let you know. The oil pressure verified seems to be sufficient. It holds 8 qts. so at 5,000 miles it should still be working well.

Where I work we get bad metal from our suppliers from time to time which causes accelerated wear on the tooling and defects. We go after them and do our best to hold them accountable but one certain supplier we would just rather kick them out. We are tired of dealing with them.

I'm sure our situation isn't unique and Ford deals with the same thing and it makes them look bad when defects get out in the field. If you got a good one be thankful. If you got a bad one that should not have ever happened you have every right to be upset.

It's sad that the work ethic and attention to detail isn't what it used to be. I like to think it was better in the past. This problem is spread throughout all of society. All industries deal with it. Think about your workplace and the things you have to deal with.

I like the 7.3. I hope with proper maintenance it lasts a very long time.

 

The 1982 Chevy 305 in their trucks had defective cams from an improper heat-treating process and the cam lobes would prematurely wear down to the point the engine didn't make any power, but they never had a catastrophic failure, and that was 40 years ago and I'm sure it took longer for warranty repair data to make it to quality control/management compared to today's online electronic reporting. Having said that, the fix was in on those defective cams for one model year and with the 7.3 we know lifters/cams were failing after 3 model years which is completely unacceptable and the Chevy and Hemi lifter failures since Mult displacement has been going on for way too many years.
