No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
I know we have had this thread before, but it is becoming incredibly frustrating since I am now changing oil every 5k and pulling 6% fuel in the oil every time. Where can oil this fuel be coming from? They are doing injector leak by test and say they are normal. Blackstone is performing the analysis. The service manager had the nuts to tell me to change 15 quarts of oil every 2500 miles! Help.

I wouldnt worry about it. Drive it until you notice a considerable increase in oil on the oil dipstick, that is if it even has a leak. Oil analysis aren't always golden. I just removed a 6.0, tore it down to a shortblock, removed the bedplate and all the bearings, I got customer pay 32 hours for the job. This is all because the customer requested I do that because his Blackstone analysis came back and the customer was advised that his bearings were worn out. Bearings ok, nothing wrong with the engine, 160k on motor. Ran ok before, runs ok now.

Oil was up 2 inches on the disptick from full. Smelled like diesel . Analysis confirmed.

Yeah that dosen't sound right. The high pressure fuel system test the dealer does isn't worth anything if the valve covers aren't pulled. Have they done that yet? There is a TSB they should have that goes over this for this concern.

There have been reports of bad high pressure fuel pumps with bad castings and bad injectors sticking open. 6% is like 2.5 quarts of diesel in 15 gal of oil. You can also have another lab like Titan labs in Denver retest your oil.

There is a good article in the May 2008 issue of Biodiesel Magazine which talks about the post injection problems that Ford and other companies are experiencing with their engines. While the article is geared towards the use of biodiesel and possible problems of mixing in with the oil too much, the article gives a pretty good explanation of why the fuel mixes in with the oil.
So NOW I understand why the manufacturers limit the fuel to B5! zit really has little to do with the fuel being viable. its all related to the emissions control method is use! THANKS!!

I will go back to the dealer with the TSB info, if I can have the number that would be great. I need to also bring back since the air has got malaria again-hot cold hot cold- last time there was a short in the control unit.
