There has been a suggestion of using a thicker oil to lesson the noise, increase oil pressure etc until I get the work done. Any comments on that? If positive which oil?
Bloody hell, engine out job I suppose..........

Chain tensioners were done on my D3 4.2 in February this year along with the cam belt and all tensioners etc - the Audi parts prices alone for that whole job can come to about £1200  but were got down to about £650 by using OEM manufacturer parts sourced mainly via ebay. The tensioners was not a fun job - made worse by the LPG system all over the top of my engine - but was do-able without the engine out although some of the cam top caps had to be loosened on one side to get to the rear tensioner. The front one on the other side was somewhat easier. the old tensioners at approx 150K miles were nicely grooved but still had a little life left in them but would not in my opinion have got to the third cam belt change before breaking or causing damage by the chains to the metal they were sitting on.
