[ROVERNET - UK] Timing chain noises 2000TC

[Vern Klukas]

Three possibilities, in my experience.

First thing, the lower chain rarely give any trouble. On to the upper chain.

First possibility is that the chain has stretched so far that the 
tensioner has run out of effective travel. Least likely I expect

Second possibility  is that the chain damper has broken, allowing the 
tension side of the chain to whip.

Third possibility is that the tensioner is so worn that the oil is 
leaking out faster than it coming in. It is also possible that the 
small plug at the end, which is used when you retract the tensioner, 
has fallen out. The fact that the noise goes away at higher engine 
speed (more oil pressure) suggests that the tensioner is the likely 
problem.
