I sent the injectors out only to find out that they in fact do not rebuild and test side mounted injectors. They could send them out for $75 an injector but after a long talk with the guy my problem may not be injector at all.

There is the question of the burnt o ring. It looks like it could have been one of the hi pressure oil line o rings from the top of the injector. I only see three with my other parts. The other three are either stuck to the injector (currently not home) or were never in place when I pulled them. I'll have to wait and see.

They suggested the fuel pump if it is starving for fuel. The pump does look like it is leaking a bit. Also, I'm not sure I should rule out the head gasket. I only drove this bus once and at the time thought it was the turbo.

I finally got the bus insured and registered today and took it for its first test drive today. No smoke at all! The injectors were retuned unchanged because they could test my type of injector. I cleaned of the tips of all six injectors with steel wool. Injector #5 from the photos above had the remains of an out of place oring broken and fried to a crisp. I also cleaned the injector cups with steal wool as well. all orings were accounted for from the oil rail but at some point one ended up in that injector cup. Someone joked about all the red rags in the head while I had it taken apart but no lost orings will get lost in my engine

Above is a great example of posting by phone. "Could NOT test" the injectors is what I meant to type.
