WTF is this from the turbo?

http://i38.tinypic.com/utpbt.jpg

i have to assume it's bad.............

I think I've got the same thing, from memory, but not sure. Better pic please?

it looks to me, to be soot mixed with water coming from the exhaust clamp on the exhaust housing.
Did it rain pretty hard there this morning or this evening? Looked pretty black and blue towards your direction from my house......

If it did, i bet it's just the rain cleaning the inside of the exhaust pipe some....it'll be fine....

all i have is a worse picture of the splatter from such:

That means you burnt up your turbo. Too hot on your EGTs.
































just kidding, looks like junk from the slobber tube. Just blowby.

didn't rain here and it was definitively oily..................

Well did you get a new radiator cap yet? Is it still using water/coolant?

No smoke or oil coming out of exhaust like maybe a blown seal on the center section on the turbo?

got a pinhole in the damned thing that i just noticed but no, the cap is holding fine now and it's not using coolant at all

Where is the pinhole?

As far as the exhaust spatter, it happens. Cover the exhaust stack when not in use to keep rain out...when has it rained? Or have you been running it under light load? That is called "wet stacking", the exhaust never gets very warm and as such, the exhaust has lots of unburned fuel in it with carbon and water.

Did you fix the oil leak on the IP?

the pinhole is on the backside of the radiator, about it the middle closest to the drivers side. theres a quarter sized wet spot and about a 5" sized section around it that's corroded from it.

so far as i can tell i have fixed the IP oil leak. however, that jet black crud coming from the turbo is oily..........

And have you been lightly running it? Normal.

just taking the kids for rides thus far really. certainly getting to temperature though.

But running it under 10 MPH? The engine can be warm but you still can wet stack it. Not as bad as indirect injection engines but still makes for a mess. Incomplete fuel burn causes soot and diesel to coat the exhaust system, it runs back and leaks everywhere. There is a gasket or you could try a bit more on the band clamp at the turbo exhaust, where it is leaking. But it ain't engine oil by any measure so relax and drink another beer.

On the radiator, can you see the hole or just the wet spot? I would hate to have to pull the tanks. That is something I would farm out to a radiator shop. Yeah, pain the the butt. Those radiators are HEAVY. But worth repair. Try some of that sealing stuff.

yes, always under 10mph but the truck shouldn't have known it............was almost always about 1800rpm. might even be from the ****ty diesel?

can see the wet spot on the radiator. the sealant stuff wouldn't hurt the block? cause it's got to be small enough to be an easy fix................

If you get it out on a long highway trip, it'll smoke for a bit then stop.

Tooling around your place at 10 MPH doesn't put a real load on the engine. It doesn't take much more fuel to spin the engine at 1800 RPM than 800 RPM, most of that additional load is from the fan. And 10 MPH takes all of 3 Hp, give or take.

Plus, it has been quite humid in your area, this adds to the mess.


The radiator sealant? It is fine for the engine, it won't plug up anything but a leak as it needs to dry and that won't happen unless it is a leak. Bar's Leaks is the best brand, it will take a few doses as that is a huge radiator. Just dump it, get it to operating temp and let it stand.

You need to take the truck out and RUN it. . .

Just looks like "Slobber". Incomplete combustion/water vapor, etc. Extended periods of ideling is a big cause, but there can be many combinations of causes. Usually associated with running too cold & slow. Usually first manifests itself by running down outside of stack. If you have to idle it, pull the throttle out and let her run at 1000 RPM.

yep get her under load, and run her hard it'll clear up after a few miles.

my truck will do this because it is humid in the woods here, and most jobs I use it for are small, but once a month it gets used like it should, and smokes to beat the band.

Like any new, proud "parent", Tex is just a little concerned.

Remember, the turbo "seal" leaks oil back to the crankcase, because the exhaust and intake pressures are higher than crankcase pressure, there isn't much oil leakage possible UNLESS the turbo oil drain becomes clogged.
