Thanks.great work BTW
I think you must have missed quite a few posts, but i did ramble on a bit!
The cause of the spark plug failure will, I think, remain a mystery.
The knocking noise was a bit of the broken plug making contact with the piston and cylinder head.
It was resolved by taking the cylinder head off and removing the debris. Very lucky that there is no real apparant damage other than very small surface marks.

Great result OP, just in time for summer too. 
Ta.I took the hardtop off yesterday evening and had a look at the hood for the first time.
It's actually in very good condition, so was chuffed with that.
I drove it around a bit last night and brought it into work today, all seems good so far!
I think the debris could be the cause of the knock, also curious when all done and noise fixed, what the causal issue is regarding plug condition, you could do without a repeat of this. Bearing pictured looks good for the miles. I've found debris above valves before now. Also had similar plug failure which was combustion temp related which caused an insert to drop out, which subsequently got broken up by the valve, then pummelled by the piston briefly at idle until it stopped the motor! Hence I say the debris, small as it is, can make a big noise.
If it were me, for fun I'd clean up the pistons properly, check ring lands aren't holding the rings etc, and run again.

Something weird has happened to the formatting on my pc so it's become much less easy to read, navigate and post on here, but I'll try for an update...
It's been running great. I've changed the clutch fluid which was quite a dark colour, and the gearbox oil. Then it went straight through its M.O.T. this week, with no advisories!
I've been quite busy cleaning it, painting a few bits and tidying things up;
Still got quite a bit of cleaning to do, mostly the hood and the interior, but it's coming along.

It's just the cam cover that I've painted.
And to be honest, it looks brighter in the photo than it really does.
I went over it with a wire brush in a drill and sprayed it with VHT silver paint, it's far from perfect but it did come out better than I expected it would.
The plastic cover, I just went over it with a damp cloth, then some Autoglym bumper care gell.

I've heard good things about Renovo hood cleaner stuff before, so I might well give it a go, thanks.
I must be honest and say yeah, I am a bit proud of how the car has turned out.
It's taken a lot of hours but I do stand there and look it now with a sense of satisfaction, even more so when driving it!

If you use Renovo, which is an excellent product, make sure you get the full kit. Comes with everything you need to fully restore the roof, off the top of my head that's a cleaning solution, a paint/dye and a waterproofer. Think it may even come with all the buckets and brushes needed as well.

Takes a full afternoon to do carefully but absolutely worth it; the difference it makes is very impressive.Sorry for the late response.
The Renovo sets are quite expensive. Does anyone know how many hoods it's possible to do with one kit (I know they vary in size, but from your experience)?
Only it could be worth it as I've got another small 2-seater soft top coming soon!
A 1979 MG Midget in fact, but I'll start another thread for that when I collect it.
As for the MR2, it's going well, and I've been enjoying plenty of commutes with the top down in the recent fine weather.
I've cleaned up the very slightly cloudy headlamp lenses.
I still need to give the interior a good going over and treat the leather seats and get a little paint work done.
