Stephen,
If you haven't drained the oil yet, or at least haven't yet disposed of
it, send in a sample for oil analysis. Then you will know for certain
what types of bearing or other wear materials ended up in the oil.
Anything else is speculation. If I were you I'd Google 'engine oil
analysis' and call a few to see who could turn it around for you quickly
so you'll have an answer as soon as possible.
That said, the typical pattern is for low oil to cause upper end wear;
and for no oil to cause crank bearing failure.

Hi,
A "friend" of mine ran their 99 mk2 with low oil (read: this could
mean none) for some time. It was eventually noticed when the engine
started making noises. Oil was added and it still running. I took it
for a spin at the weekend, it accelerates + idles fine, no noises, but
when lifting off or *just* slightly applying trottle it makes a cyclic
deep click noise. Its been suggested that the crank is done for, but
it sounds more top end to me.. actually.. the engine feels pretty
strong. I suspect its had its engine wrung out on a regular basis too ;-)
What should I be looking at first here? What kind of damage?
Likely the noise is crank floating back and forth?
Cheers,
Steve
