110 went bang

My 110 LWB 2.5 N/A diesel went bang on Monday.
Any clues on which bit of the engine it might be.
Symptoms are: Gradually increasing black smoke, loss of power gradual - but
might have been the MOT station backing off the fuel mix for the emissions -
have been gradually winding it back out. Tappit noise.
Terminal symptom was big cloud of black smoke and no power worth speaking
of, was very glad that I was not on a slope when pulling into a handy
gateway. Every few revolutions there is a sort of clacking bang.
Help.

Hi Amanda,

Sounds to me like a bearing has come adrift or a piston is not well, the
black smoke sounds like ol is getting into the chamber. I think whatever is
the conclusion to the problem, it is an engine rebuild or engine swap.

Not probably what you wanted to hear.

Dropped valve or failed hotplug [precombustion chamber]?

sounds like something nasty. than banging sounds like a broken piston to
me. why that would make *black* smoke, I dunno.

Hunt another engine, probably.
