6.4L making oil

[dieseltechinco]

FYI

I own a Diesel repair shop in Colorado and mostly work on Powerstrokes. We have noticed that every (all) 6.4L that comes in for an oil chage is 2 to 8 qts over filled with oil? It is not oil but fuel in the oil, from what we have heard Ford engineers are saying this is normal (I say B.S.) They are saying this so they don't have to address the problem. If you own a 6.4L this will become a serious problem in the future with seal/gaskets blowing out and bearings washing out. This will most likley happen when your warranty runs out.

I just want 6.4l owners to be informed about this issue.

thanks

Welcome to the site Its a known fact. The regen process causes it. DPF deleted trucks dont suffer from this issue

Thanks for the info. We all know all about this. We have our own ways of fixing this. I was getting quite a bit of this when my truck was stock, but not any more (sans DPF).

BTW..

I'm glad to see people aware of this issue, I wish I had more time read the forums but I'm too busy fixing 6 liters all day. It's a good thing I can work on them because I couldn't afford to one other wise.

I have 6.4l in my truck and I would like to know if there is a fix for the fuel in the oil, with out having to do a DPF delete? Also I have another issue that when I am driving around in the city i have no issues till I get out on the highway and hold a steady limit for a hour or so and then I loose throttle response. It has happened to me 4 time within 1 hr before and the other 2 times where spuratic on a trip back from Florida to TX. I am short of trading it in if i cant get it fixed!

What helps to minimize the fuel in oil on a stock 6.4 litre is to let the regen cycles finish. Shutting the truck down during regen is the main reason the fuel ends up in the oil.

Not to sure on your other issue.
