6.0L fuel in the oil

[2005powerstroke]

What are the reasons/problems that I'm getting 4% to 6% fuel delution in the oil. The oil is tested every 3000 to 5000 and is changed at testing time. I've been told there should be no fuel delution in the oil. Please help me get this problem figured out. Thanx, Chris

I have had this issue as well for the last two years. Dealership replaced 4 injectors on the driverside and the problem is still thier. I'm back at the dealership again less that a year later and they are telling me that two of the 4 they replaced last year are sticking but they are 700 miles out of thier 12K mile warranty. So, I don't know what the hell is wrong, no smoke, truck runs fine but I am getting an extra 3-4 quarts out when I drain the oil and is is very this and smells like diesil fuel. I sent some off to Blackstone for analisis and they said I have 4.5% fuel contamination. I change every 5K.


The only thing I can think of as a resonable cause is that the injectors are stuck open and I have extra fuel going past the rings or the top O-ring on the ingector(s) is damaged allowing fuel into the valve cover.

there's a tsb 04-9-3 for the 03s and early 04s.

you're supposed to drain the oil, leave the plug out, remove one banks fuel line from the housing and block it off, dye the fuel in the secondary housing, power the pump and see if you get dye out of the pan. if nothing then do the other side. if end up with dye in the pan then you should know which side its coming from. pull the valvecover and look for which injector body or oring is leaking

more than likely injector o-ring(s) leaking, a fairly easy fix as long as you know which one it is. the leak down test mentioned above will let you know which side it is.

Change all eight injector o-rings and be done with it.

Go to your nearest Ford dealer and order up eight kits (part number CM-5055). For what they cost, you are better off getting them from Ford (read: DIRT CHEAP).

As for the passenger side, that's what a stubby ratcheting 12mm wrench comes in handy for, along with a 10mm one too.

Well then, a trip to Ford and Sears is in order. Thanks again for all the help.
