Blue Smoking 6.4??

[mazsecond]

I'm a frequent poster over in the 6.0 sections but I don't know much about the 6.4s and have a question for you guys...

I saw a 6.4 pull into a parking lot today just after I parked my truck. As he drove in a trail of whitish blue smoke followed him and then he must have punched it for a second and a plume of this whitish blue smoke poured out of the exhaust.

I waited for him to get out of his truck and went up to ask him if he knew what was wrong. He told me that about a week ago the company he works for added some kind of additive to his oil which the company uses in their 6.0s to clean the injectors. They wanted to see how it would work on his 6.4 because he drives a lot. He told me the truck started smoking a few days after they added this additive. He didn't know the name of it though. His truck was all stock, stock exhaust and stock tuning.

So what do you guys think this could be? Have you heard of something like this before? What could this additive have done that would make the truck smoke like that?

I should also note that his tailpipe was completely coated in oil.

It sounds to me like it could be a turbo seal.

From reading on here thats what it sounds like to me also, but from what he told me it sound like the truck was running fine before they put this oil additive in and now the truck smokes and is clearly leaking oil. Is their some sort of additive that could possibly cause this. He said the use the additive in the companies 6.0s to clean the injectors. I really wish he knew the name of the additive.

Could this just be a coincidence?

I would say coincidence. I am by no means an expert but i cant imagine an additive would make it spit oil out the exhaust. Maybe he ran his ccv vent into the exhaust but i doubt that as his truck is stock.

Thanks. I couldn't imagine that either. He didn't seem too concerned about it bit can't a bad turbo seal run the engine out of oil and spin all the bearings

Hopefully we can get some more 6.4 guys to chime in and see what they have to say and if their ever heard of anything like this. I just hate to see powerstrokes going down the road with smoke coming out the exhaust.

Ya for sure. If I had oil coming out the exhaust i would be concerned lol.

Take the down pipe loose from the turbo and see if there is a lot of oil in the tail housing, I second a turbo oil seal. The heat from regens eat them alive over time.
