I have a 2001 2500 4x4 170k, Truck is Totally Stock I have owned the truck for about 1k miles, I did the first Oil change on it this weeked and we took about 15 or 16 quarts of fluid out of the Crank case the Oil looked very thin and Smelled like Fuel. It look like a New Injection pump we put on the Truck recently It has a Bosch Reman Sticker on it and a Warrenty void if touched sticker on it.

Any Ideas? is this a Dangerous condition, I need to use the truck?

Thanks,
Fred

Sounds like you may have a leaking injector, and yes, fuel in the oil is very, very bad for the engine. I would not even start it until the problem is addressed.

 

how do I determine which Injector is bad? how hard is it to replace them? I have done a lot of work on Gas Engine but have never worked on a Diesel.

 

most likely its the oring at the top of the injector. first time diong it 3-4 hours.
unless you very good with a wrench . then much less. you can get the o-ring and maybe the copper washers for the bottom of the injector from many places.
its just like changing out the injectors for new ones. except your replacing the washers and o-rings.
mighty be a nice time to upgrade if possible, or get new ones. i dont seggest going to the dealer for this stuff. cummins will sell to the public in most cases. or call one of the many wonderful site sponsers. thats why they are here! and not to expensive either

its more time consuming then hard. if you need instruction and cant find some. feel free to private message me.

 

Yes, they're very easy change, should take a couple hours your first time, as Bio said. As for how to tell, I think you'd need to take them to a shop to be pop-tested.
BioRunner is also right, the dealer will rape you on the parts. The Cummins dealer would be a better choice. Sometimes there are new or slightly used sets for sale on eBay for cheap. It would indeed be an excellent time to upgrade injectors!
If you're anywhere near Northern Kentucky, PM me, I'd be glad to help.

We have a shop here in Detroit that is a Borsh Cert'd Rebuild shop. (where I got my parts) they think it may be the Dry seal on the pump. They said the truck would start to run poorly if the Injector is leaking. They gave me a Dye to put in the Fuel Filter housing , said Remove the Valve cover Start the Truck and look at with a Black or Leak lite. If I see stuff in the Top of the Head it is an Oring If I don't see anything it is a Dry seal (on the pump). This Sound logical to you Diesel Expert. They told me that the pump workings sound ok cause the truck runs good, and they work Replace the Seal and recert/test if for around 160 buck.

 

Sounds like a good plan. I never thought of a seal on the VP44... makes sense though.

 

Pulled the Valve cover last nite and Started the truck, I found Bubbling around the 1 and 2 Injector, sounds like a leak of some kind to me. Pull all the injectors and am going to have them tested and cleaned today, Then will reinstall them and see if that licks the problem.

Thanks for all the help, thus far.

 

Looks like BioRunner hit the nail on the head, I had the Injectors cleaned and put new o-rings, copper washers, and O-ring on the transfer tubes. and It looks like this issue has gone away. I'm was told by the Fuel Injection shop that I should add a Lube/anti gel Agent, cause the New Diesel is hard on the pumps.

Thanks for the help,
Fred
