sut on back of turbo?

[DuraWhat?]

I was doing my weekly check to see if my coolant has puked and noticed black sut on the back of my turbo, downpipe, and on the top of the egr cooler. Any Ideas as to whats going on here? Do you think there is a crack in the back of the turbo?

Thats the best pic I could get of it.

If you had a 7.3 I could tell you exactly what would cause this... but on your 6.0 I'm not 100% sure... so I'll let a tech answer before I send you off on a wild goose chase.

PS... free bump!

Probobly the uppipe gaskets or donuts.

You say donuts would that be the "gasket" between the uppipe and turbo?

[vitalidle]

Well actually where the two uppipes meet. I don't know the name off hand but its where the exhaust gas flows into the turbo. Wish I had a good pic. Hold on I think I have a pic to show you.

It just came to me the y or where the two uppipes meet is the collector. That is where the donuts will go.

It could be the downpipe, or one of the several connections on the y-pipe. The flex joints are prone to cracking also. There are some flat thin steel gaskets between the sections of the pipe, one of which is between the y-pipe and the EGR cooler. There is no gasket between the uppipe and the turbo or the downpipe and the turbo. There are no donut gaskets between the manifolds and the y-pipe.

Right and I probobly confused you by talking about the 7.3 with the donuts. Anybody have some coffee to go with the donuts

Good deal, So, this is a problem I can take my time to look for. It will only continue to make a bigger mess right?
