OM648 What are the signs of leaking injector seals?

[shertex]

I have permanently removed the engine covers (finally) on both of my CDIs. So no fear of black death.

When the injector seals do eventually begin to leak, how will I know? Will there be symptoms I will observe?

I do have an exhaust sensor...maybe just check once a year or so.

Just look at them every few weeks is what I tell my customers. It is quite evident when they start.

What will I see? Puffs of smoke?

Look closely at the base of the injectors. You can see the black tar like substance. It will start out small.
