Last month I posted a question (click below) about my 6.4 getting diesel fuel into the oil.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
<o></o>
After suggestions from this group I took it into the local Ford dealer. Thought I'd give you guys an update.<o></o>
<o></o>
Dealer worked with Ford folks and performed a number of checks and test. They found one of the exhaust pressure sensors slightly out of speck so replaced it. This didn't have anything to do with the diesel in the oil.<o></o>
<o></o>
After all the test they concluded that with the load (17,000 lbs RV, 75% of miles) that I tow I should get about one quart of fuel in the oil per 3000 miles of pulling. According to them everything is OK?<o></o>
<o></o>
Will be on the road again next month so will see how much oil/fuel I drain at the next 5000 mile oil change. I give you another update then.<o></o>

I would short stick it everyday if I were you.

I assume they check the injectors to see if they were leaking?

 

By short stick it I assume you mean check oil level on the dip stick??? I now will check every time I hook up and pull out.

I can only assume they checked the injectors with the testing they did??

Maybe I should call dealer back and ask?

 

Yes the oil level on the dipstick. I would monitor the level closely.
Personally I would do my best to ensure they checked those injectors. They may or may not of.

I would assume there would be something written on your ticket when you picked the truck up.

 

International came out with a recall concerning an issue with the injector o-rings on these engines leaking fuel into the oil. The upper o-ring will cause this fuel in oil problem. International was able track down the specific injector serial numbers and which engine serial numbers had these defective injector o-rings. It even listed which cylinders they were. We then just replaced the injectors required by International.

I don't know if Ford has done the same thing in some form, but I don't see why any Ford engines would not have had this defective o-ring problem as well.

What needs to be done is the valve covers removed, then fuel system pressurized, and the upper injector o-rings inspected for fuel leakage into the crankcase.

Another problem that can happen is that if the engine was at some point taken apart (or not put together correctly at the factory), the metal injection lines under the valve cover going to each injector can leak if reused. The metal lines are NOT reusable as they are a one time swage when tightened down. If they are used again, they have the possibility to leak. This will also cause fuel in the oil.

Fuel should not be getting in the oil, period. It isn't normal on any engine.

 

Ford did the recall, here it is:
Fuel injector replacement, Field Service Action 07T07:
Certain trucks built at the Kentucky Truck Plant between 4-3-07 and 5-21-07 have three injectors that may have had their polarity reversed. Applicable trucks will have injectors replaced on cylinders 1, 5 and 7.

 

This recall that International did that I am talking about wasn't a polarity issue. It was an o-ring issue causing fuel in the oil.

 

that was the only one I that I can recall for ford.

 

Do you know when this recall occured? I have a 2008 F450 w/ the 6.4 diesel built in Jan. of 2008.

 

I'm not sure, but it may have only been International specific. I'll log into the International website tomorrow and see what the date was on it.

Even still, you shouldn't be getting fuel in the oil. It's not "normal"...

 

you can also go here and put in your vin and it will tell you:
Recall Information - Ford

 

Most people think the fuel in the oil (like qts of fuel) is from the regens...that makes me laugh.

 

Adam is correct. There was a recall of injectors for leaky O-rings. I know, my truck had the work done.

I have Job 3, 2008 F350 that had five injectors replaced. The notice covered trucks within a specific VIN range. As I recall, it was primarly Job 3 2008 built trucks but may had involved some Job 2 2008 trucks. My truck was built in Aug. of 2008. (Must of been one of the last ones off the line before the 2009's started being built).

Anyway, it's a cab-off process (not as big a deal as you'd think) and they did it in a day or so.

If you're in doubt, call a dealer and have them run your VIN. If it hasn't been done and should be, they can tell you (hopefully).

Enough said.
