Smoking, on throttle. Various amounts, but particularly noticeable on large throttle changes.

Oil and filter were changed yesterday. There was a trace of debris in the oil. Fine metal non-magnetic 'dust'. A large item that came out was what looked like a calcium fragment about 1mmx1mmx0.5mm in size.

Compression check shows,
#1-7 = 13bar to 14.5bar.
#8 = 9bar

Plugs, all tend to be darker
#1,2 dry, a little dark
#3,4 wet, oiled
#5,7 dry, a little dark
#6,8 wet, oiled

Only #8 correlates lower compression with an oiled plug.

choices-
rag it until it dies spectacularly
mothball until time and (another) replacement engine is sourced. (planning on this option)

Is there anything I should be aware of?

And if anyone has a good 3.6 or 4.2, long or short engine, I'm interested. Again
