From the album: Air Management Failures
This is the turbine housing that goes with the turbo in the previous picture. Rust here can also lock the vanes solidly in place© Keith Browning

Here is a classic example of a turbocharger from an engine that sits for long periods of time. Rust and soot coat the surface of the center rotating housing, either of which can eventually cause the unison ring to bind.© Keith Browning

From the album: Air Management Failures
An example of corrosion that renders a turbocharger non-servicable. When rust is this bad and the surfaces are pitted the center rotating housing must be replaced. This is a Variable Geometry turbo from a 6.0L Power Stroke diesel. -

A closer inspection of unison rings is necessary to identify wear. Here, the control slot is badly worn due to the higher loading caused by sticking or binding. This wear will cause turbo surge.© Keith Browning

A 6.0L Power Stroke diesel turbocharger unison ring. Observe the cracks at the inner edge where the vane slots end. The ring was stuck on the center rotating housing and would not move.© Keith Browning

There is no mistaking that this EGR cooler has failed. This is the back end there the cooler connects to the right turbocharger inlet pipe.© Keith Browning

Another look at an LCF 4.5L Power Stroke with a leaking EGR cooler. Again the white stains in the EGR valve bore are the tell-tale sign of an internal coolant leak.© Keith Browning

With this intake manifold flipped upside down we can look directly into the EGR port. This is a perfect example of the carbon that builds up sometimes breaking apart. In extreme cases this passage will become completely blocked.© Keith Browning

Inside the EGR cooler where loose carbon also known as EGR marbles can be found. Engines that produce a lot of carbon sometimes fall victim to this however it is more common when an EGR cooler slowly leaks coolant into the cooler over a long period of time. That causes a lot of crusty carbon and coolant residue buildup© Keith Browning

This 4.5L Power Stroke diesel EGR valve is showing evidence of a leaking EGR cooler. The white stains are coolant residue. Unexplained coolant loss can be caused by a leaking EGR cooler and pulling the valve can be a quick way to verify your suspicions.© Keith Browning

Another EGR problem is formation of dry, hard carbon build up in the EGR cooler and the passage between the cooler and the valve. This carbon can break apart and cause chunks to become lodged in the EGR valve holding it open.© Keith Browning

From the album: Air Management Failures
Probably the first thing people used to think of when talking about a 6.0L Power Stroke diesel engine is clogged EGR valves and this valve is completely clogged with carbon. Along with poor quality fuel, anything that causes incomplete combustion, misfiring and elevated oil vapors in the crankcase ventilation system will worsen this condition. Improved engine calibrations have had an impressive affect on preventing it.© Keith Browning

This must be "one of those" trucks that are just a problem from day-one. I have one or two of them. /forums/images/%%GRAEMLIN_URL%%/rotz.gif No matter how well I repair them and look them over they just keep coming back and it's always something different for the most part. You alsomst want to blame the owner and sometimes you can but I honestly beleive that some trucks are born to be bad!

As I know it, Stanadine products are the only Ford approved additive. It is also important to note not to use any fuel additive that contains alcohol in any Ford diesel fuel system. www.stanadyne.com
