Re: Timing belt and Tensioners
Variator works on OIL PRESSURE. If it is noisy at startup, then that because the oil has drained out, or the oil is thin. If it continues to sound like a diesel then the variator is worn and needs to be replaced.
When did you last change the oil? It might be worth trying an oil change.
And one or two people have used ENGINE FLUSH to clean the engine oil ways first, then refilled with 10W60 rather than 10W40.
I'm concerned that by tightening the belts they are going to cause a tensioner to fail ...
