Right so ive got the head off now, nothin wrong with valves all looks inorder no signs of anything bad. I know the timing is right atleast for the fuel pump.... So am i now lookin at a broke piston ring?

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

chris freestone · Nov 13, 2013

Yeah lil shiny but looks good realy, not mishaped

chris freestone · Nov 13, 2013

Bit shiny/glazed maybe but dont look worn or outa shape id dont think

Does the tapping get louder when you remove the oil filler cap?

Any vertical score marks or a lip at the top?

chris freestone · Nov 13, 2013

Lip at the top, how much bad news is that?

chris freestone · Nov 13, 2013

Never tried listenin with the filler off

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

chris freestone · Nov 13, 2013

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?

jamesmartin · Nov 15, 2013

it looks a little like valve cap has had top worn off leaving a collar around valve stem presume there was a large-ish gap

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