[MV] Detroit Diesel 6V53 Problems

My Detroit Diesel 6V53 is behaving badly and I need some help.

Do we have any Diesel mechanics on the list?

Here are the symptoms:

- It idles nicely and runs okay both loaded and in neutral up to
about 1500 rpm.
- Above 1500 rpm the exhaust note starts to break up and gets
progressively worse as the revs are increased. Under load the
engine lacks power.
- Condition is getting worse with time.

I do have an algicide in the fuel, but only recently.

Being a tracked vehicle it gets very little (almost none) use.

I would have thought that if the problem was something basic, like
dirty filters or water condensation, the engine would surge or stall,
mine just runs rough?

So before I start replacing everything, any suggestions?

Could the diesel, which is at least 3 years old, be stale?

Governor problems?

Have I got major problems?

Please send replies direct to me as I doubt most list members
will be interested.

Thanks
Doug
