Foul plug could be a sign of either worn oil rings or valve guides or valve guide seals.

:agree:  with Cam.
I had a Mini with the same symptoms, ended up using a hotter plug in the cylinder that was crook. Only a band-aid solution.

How do I go about working out whether that's the reason or not? Is it worth buying just a single hotter plug and putting it in and seeing? And if that is the problem, how long is it likely to work for with the hotter plug before it plays up and needs a proper fix?

So I checked and supercheap have the BPR6 FS plugs in stock, which is the slightly hotter version of the BPR5 FS I'm running. Is it worth just buying a full set of the 6's and running them in place of all the 5's I'm running at the moment? (My engine doesn't run real hot, it's quite a moderate temp.) Or is it worth replacing leads first, replacing the foul plug, and seeing if it all works, before going to such an extreme?

Mattrix:
On the issue of running on less cylinders, I found one of the leads had a crack in it and was shorting on the block. Replaced it, and it's still running on less cylinders, but it turns out it was running on 6cyl before... no wonder it felt like an absolute pig. Running on 7 now and will be replacing the rest of the leads within the next couple of weeks.
Which leads me to... Plenty of new parts are now on their way! Corvette Central posted a whole bunch of odds and sods for my car (including some AC Delco plugs, as well as some new arm rests), can't wait to have them all in my possession, and then can't wait to have time to put them all in. But then I'm just one step closer to selling it... Good and a bad thing really.

MADVET:
A handy tip i discovered by accident, If you run your engine in the dark you can usually see which one of your plug leads are arcing.

Scott:
Another not so handy tip: if you wriggle the leads while the engine is running, you may be able to feel which one is arcing.

Mattrix:
So after more playing around, it turns out that one of the plugs had gone bad. I'm thinking it was because of the dodgy lead, because after I replaced the lead, then replaced all the plugs, the issue hasn't come back. So it's running how it should now, which is nice!
Re: windscreen, bit the bullet and am getting O'briens to put one in for me on Friday. $808 later (though they are including free chip repairs on it for life, which is worth about $150 I think she told me), I'm gonna be a bit sore in the wallet but then at least it's done (And I only JUST passed pink slip the other day, he told me I passed but that I have to go get it replaced, and I'd rather this guy not get into trouble as this workshop has looked after me before on numerous occasions).
