Exclamation Fuel in Oil

I have a 2002 Duramax and I just had the injectors changed under warranty. I picked it up and used 1/8 of a tank of fuel in 25 miles. I stopped and saw iol dripping from the front of my engine. the dealership is now telling me that they reordered new injectors and a line. They are also saying the only other thing that could be causing the fuel to go in the iol is the injector pump. Service manager there says he has only seen two go bad and they were cause by water in the fuel and gas in the fuel. Any comments on this would sure help.

I have an early 04, so it should be the same as your o2, and just received a factory notice that they are extending the warranty on (at least) the 04 models to 7 years or 200K miles for cracked injectors, listing one of the symptoms being fuel in the oil.

its one thing for them to repair the problem, but my big concern is that what are they going to do about the potential damage to the internal engine components with fuel in the oil. I have always run Delo 400 in all my diesels (2 rams, and one duramax - I miss the dodges soooo much) because I believe that you'll get out of your truck what you put into it. So, if this is happening, regardless of what oil you use, when you add a bunch of diesel fuel to the engine oil, you significantly modify the lube properties.

I also have a 02 duramax and had the injectors replaced (7 yr / 200K mile warranty) at 64K miles after having oil and diesel drip from my truck as well as pulling a DTC 1093.

Yesterday I was driving my truck at 45 mph when it threw another (8) codes and would no run faster than 5 mph (also sounds like a two cylinder fork-lift). I had it towed to the dealer and I am just waiting to find out what happened. The main DTC was P0201. Did any of you guys also experience this?

Fuel in Oil

Yeah they replaced the injectors under warranty. My main concern is what damaged did all that fuel have on the engine due to crankcase pressure. I know I had at least 6qts. of fuel in my oil on three seperate times.

You might want to double check this with a more experienced member, but I don't think the pressure should be any problem since the Duramax blocks have a type of overflow tube at the front passenger side of the block. This is the location all the oil/diesel mixture exited my motor and covered the bottom of my truck. Thankfully diesel does not break down oil as fast as gasoline.
