I own a 2000 F350 7.3 4X4 crew cab with about 60,000 miles on it. At 3,000 miles it instantly ate 2 quarts of oil during an 800 mile trip. From that time on it used about 1 quart every 1,000 miles. All this is documented with Ford, and the dealership did a couple of oil-cunsumption tests, which proved what I was telling them. Ford provided documentation that stated usage of 1 quart every 900 miles is acceptable in a powestroke. Acceptable to them, not me. The MPG is,(and always has been) 12.5, and the power seems to be steadily decreasing. (I'll post about the rear-end vibration later). I could use some advice. I only post now because I can't get satisfaction from Ford.

 

SOMETHING IS SERIOUSLY WRONG, I HAVE A 97 DIESEL AT 103,000 MILES AND I HAVE ONLY ONCE HAD TO ADD OIL BETWEEN OIL CHANGES, AND THAT WAS DURING THE HOTTEST PART OF THE SUMMER AND SOME SERIOUS TRAILER PULLING. I LIVE IN MICHIGAN, THE LAND WHERE THE WEATHER NEVER STAYS THE SAME AND I REALLY CAN'T COME UP WITH A BAD THING TO SAY ABOUT MY POWERSTROKE. YOU GOT ONE OF THOSE MOTORS PUT TOGETHER IN THE LAST HOUR BEFORE CHRISTMAS VACATION.

Wow! Somptin ain't right there!

I just clocked up 45,000 - never had to add oil and power, if anything, seems to be better as it's gotten 'worn-in.

I'd stick to FORD on this one - get some answers from them.
If you scream loud enuff and long enough, someone at FORD will take heed.

You can always 'casually' mention to your FORD dealership that you think the time has come to contact FORD HQ to 'get some answers' - that may chivvy them along some?

Sorry to hear about your hassles though - that's a bummer

 

I heard that their is a breakin period psd! If not done correctly your psd rings might not seat completely causing oil comsumpsion. I' not sure if it's your problem. I have 63000 mi on my F350 psd and burn very little oil! Good luck!

 

We have a liaison guy who takes care of engines returned from Ford plants because of problems (with the engine) who bought a 2000 F350 to pull his camper trailer with that was using excessive amounts of oil (exactly how much, I don't know). When we find out why, I'll post it here. If you can get me your engine serial number I can see how close it is to our guy's number.
You obviously have a problem but Ford is in the driver's seat here and if they don't want to fix it, you are basically screwed. I don't think the Lemmon Law will even do you any good in this case.

 

I am not sure what numbers I am looking for, but here is what I see under the hood. It was built in Indianapolis on June 12, 2000. The number under the bar-code are AEOO2AO, and on that same sticker is the number 1390218. It appears that the final assembly point was KTP LT. TRK, wherever that is. Thanks for all the input from everyone.

 

1390218 is your serial number. I'll see what I can find out about it Monday.

 

I checked our data base and your engine was built June 9, 2000 on second shift and went straight through the system without a hitch and was shipped June 12, 2000. There is nothing to indicate that anything occured at our facility that would indicate a problem of any kind. I still have no information on our liaison man's engine other than the fact that it was built in September of 2001 so it is nowhere near your serial number. He has asked me to take his engine apart for the purpose of finding the cause of the high oil consumption but as yet, I haven't seen the engine and I don't know where it is at. If I get my hands on that engine and find the cause of the problem, I'll post it here. Sorry I couldn't be of more help.

 

I got my hands on our liaison man's engine last night. His serial number is a lot closer than I thought. Your engine was built June 9, 2000 and his was built September 19, 2000. I got some pieces to send to the lab and as soon as I get the report back I'll post the findings here.

 

Here is what we found on our liaison man's oil burner: The cylinder bore surface finish was too rough as machined. After the engine has a few thousand miles on it, the best place to measure to determine "as machined" surface finish is down at the bottom of the bore beyond where the ring travel is. The specs. are 15 to 30 RA (don't ask me what it means because I don't know) as measured with a profilometer (the lower number is smoother). Only 2 bores were in specs with the other 6 bores out of specs. The best one was 21.2 and the worst one was 70.3 (the average for all 8 clinders was 44.675) -- too smooth and the rings won't seat, too rough and you'll get premature ring wear and/or excessive oil consumption.
Our Quality Auditor did a study on this oil consumption problem as it relates to improperly honed cylinder bores, and the reason for this study was because we were having high oil consumption in our audit engines and we wanted to know why (we didn't know the surface finish of the bores were out of specs at that time). The interesting thing is, the engines in his study were in the 141xxxx serial number range. Our liaison man's number is 1471915 and your number is 1390218. Without checking your specific engine's bores there is no way to know for sure but I'd say it is a safe bet that your problem is the same as his (it is in the serial number range).
All this information doesn't solve your problem unless you can get Ford or International to agree to replace your engine under warranty (Ford should NOT have to foot the bill on this one because it is International's fault -- assuming the bore finish is the problem).
One of the motorheads I work with took one look at the bores when I got the heads off and said "they look like they were honed with a landscaping brick!"

 

 

Wow. I can't believe all of the information you were able to dig up. I will persue it with Ford, and see what comes of it. If anything, I will post here. Thanks for all of your time and effort.

 

I posted elsewhere about failed water pump, oil pump and oil leakes, etc.....I change my oil regularly but haven't really noticed it going low...except for the notes found on my warrenty repairs that say the oil is low....With seals constantly needing replacing due to leaks, could the real problem be in the surface areas to be sealed? Is there anyway to check on my engine and problems around the time it was manufactured? THANK YOU

 

How much oil consumption is excessive for these engines. I just bought a 2001 and it uses 1 quart per/1000 mile, the truck has 33k on it. Looks like this might or might not be normal according to some of the post????

 

I worked as a service writer for Ford awhile back and not in Ford's defense
all manufacturers will tell you that 1qt every 1,000 miles is acceptable useage. Never could get a real answer on how they could accept that but they do.
