....uhhhhh there is a Mustang in Tucson that used to run TWO turbos from an older Dodge/Cummins truck. They were too small so he had to go aftermarket. Saw it go 8's and I believe it has run into the 7's.......and he drove it to the track.

.....and on to the point at hand. I would love to post some sort of reasoning as to why you would replace a turbo for this issue but I'm drawing a blank. To tell you the truth I'm not sure how one would go about diagnosing this and actually pin pointing where the problem is. A difficult situation.

 

Well at least you're getting a new turbo even though it's obviously not the problem. Just goes to show how lost some of the newer mechanics are when a computer doesn't tell them what's wrong.

 

The symptom you describe with the excessive fuel in the oil is a failed injector seal. It is a common problem on the third gen trucks with chip kits where the engine temperature is allowed to run a bit higher than normal and the seals get hardened from heat. They will crack and let return fuel dump into the casting where it finds its way back into the engine oil.

Use a stethoscope and listen to each injector as it idles, and you will hear one that is gurgling like a bad sewer line. Pull that one and install the body seal upgrade kit from Cummins. Be sure you follow the proper procedure for pulling the injector, or you will damage the body.

 

I was at the dealer today getting my center console replaced under warrenty. While I was waiting I asked the service writer what was up with my buds truck. He told me that the turbo was blown, which let the truck to run to rich and let diesel run in the oil. HOW? My buddy (chad) showed up to pick it up while I was waiting for mine. He told me that they replaced the turbo and changed the oil for 60.00 bucks. I guess we will just have to wait and see how long it runs. It sounded ok as he drove away.

Thanks, Mooseman

 

Guy that diagnosed that sounds a lot like a "diesel specialist" I used to work with.(!)

 

SO WHATS THE SCOOP? Was that the problem? We are still curious....

 

Sorry it tk so long but I have not seen him. He only made it for a day or two and had to be towed back. This time they said its the injector o-rings so they replaced them and so far so good. Ill know more when I see him again.

That sounds a lot more logical than "The turbo's bad".

 

Bang on RCW - well done.
