They meant to be vw specialist... Volkmaster  basically I drove there and the guy popped the hood and said definitely issue with the chain, at this point I did explain there is no noise when cold only when fully warmed up. Basically it sounds as if chain is clanking against the cover. I’ll speak to them in the morning properly but all I got told was bad news...chain still noisy when engine warm and checked oil pressure it was very low.

To me in other words it sounds like not enough pressure causing less lubrications for chain hence the noise?? I think that’s what he was trying to say?
Am just throwing money here...  :cry:

Sorry to hear that. I think you might have an engine problem. Something along the lines of bottom end bearings causing the mentioned noises when the engine warms up and oil thins. Obviously I don’t want to diagnose over the internet without even hearing the sound but this would explain the low oil pressure when the engine warms up and potentially the noise you are hearing from the play in the bearings. Hate to be the bearer of bad news and hope I’m wrong but you may need a new engine if it’s the above.
I would go and get a 2nd opinion, maybe even at the nearest dealer. Get the master tech to try and diagnose the issue. Good luck

The strange thing is the noise is definitely coming from inside the timing cover..... am new with all this but I’ll try upload a vid. If you imagine the normal tapping noise you get but the noise a lot louder is what am getting. Basically something is causing the chain to be noisy.

You would also hear bottom end bearings make a terrible noise under load?
You can locate source of noise on an engine with a length of tube held to the engine and your ear!
As I previously mentioned low oil pressure not tensioning the chain..... It could also possibly be a worn oil pump or a minor blockage in an oil channel.... The flow rate of oil would increase with revs, thius increasing oil pressure, tensioning the chain.

Unfortunately, it sounds like a more serious engine strip down is required, based on what has been posted.

Does the car have a good history of oil changes & filter?

If the oil history is not the best, I would suggest running an engine flushing oil for a short time, then refilling with new quality oil & filter.... It may not make any difference, but cheaper than engine work & you will learn something from the exercise?

It drives spot on....no noise whatsoever under load just the annoying noise when idling(low revs)...not sure but when stationary you Rev the engine on low revs the noise gets louder but as soon as the revs start increasing the noise disappears and sounds normal?

Forgot to mention yes it has been serviced regularly so not sure?

Oil pressure is low at tickover.....how low,,,, get then to check, probably using an external guage is best. Remember, hotter oil = thinner = less pressure at idle. So idle oil pressure will be higher for a cold atart.

So back to oil pump wear or blocked oil channel as mentioned... If the chain has stretched slightly, it will be longer, can they asses how much the chain tensioner moves to take up the slack?
It obviously moves enough when higher oil pressure forces it as revs rise, but is it making enough contact when idling, is there slack in the tensioner mechanism?

Could you just put a GTD badge on the tailgate and tell everyone, it's supposed to make that noise idling? (sorry!) :)

Haha yeh good idea high modified gtd lol
Am going to speak to them today and find out how low the pressure is and I’ll ask the question about the tensioner mechanism..I can say for sure the  previous owner knew this that’s why engine oil was above maximum.

Very low oil pressure, plus a oil pressure actuated chain tensioner, could lead to a loose chain at idle slapping about. Fingers crossed it's just a partially blocked pick up or something equally cheap and non-terminal.

Your best option is to sell it to the trade. WBAC.
