I think a broken ring can make a ticking sound, not seen it myself tho. Do the bores seem to be in good condition?

Valve stem caps can wear through, that will open your tappet gap's. I read that you have it to bits now, so you will be resetting the rockers when your done. Check the caps for wear before you do.
Mine started 'tapping' and a heavy breathing sound could be heard from the air cleaner... No. 4 Rocker set had opened quite a lot.. resetting cured the noise.

Depends on how deep it is. The lip is basically the amount the bore has worn. Also sometimes the top ring can hit the lip and break. If there is a lot of wear you may get piston slap, which can make a knocking noise.

quite bad if it is tdis dont normally get bore wear till they are buggered, wear should be worse on passenger side and non on front and back of bore , it could just be carbon build up

Yeah will be redoin tappits, hopefully should make some difference to.the sound, but doesnt account for loss of power and all the smoke i dont think. Im gona pull the pistons on saturday and check the rings, then ill just reasemble and fingers crossed

I had the same problem but with my 300tdi. It turned out to be my tappets that need adjusting. Im not clued up on 200tdi's.
If the tapping gets louder when the oil filler cap is removed then it's more than likely your tappets need adjusting

Oh sorry didn't read the power loss and smoke.
Could be valve stems which would explain the smoke and power loss

So would tappets bein out also give ya plooms of smoke and bad startin? Its hard to pinpoint the moise cant realy here with ya head under the bonnet youv gota be stood abit away from the engine till ya hear it then its very clear

if far out it means valve opening is delayed and gas movement is restricted can give smoke and crank case pressure

I had an old reno 5 gt turbo amd when the valve stem seals went on that it caused smoke on tick over#because oil drops into the cylinder doesn't it?

Do these marks around the top of the valves indicate anything or isit just normal wear n tare?

usually blue smoke on start up but you wouldnt notice power loss
