I am really sorry, But unfortunatelly I do not understand your English :S
So what is the current status? Are you a TS owner or not?! Or what was this talk about CTR? Oil? Aham you mean that 0W-40 is too thin?.... Hm One of my friend put into 5W-35 ( what is anyway the official introduced one... ) and don't know why, but the noise once "appear"... So now there is another point of view, so maybe the belt fastener?! , or the belt became too loose, I think its quite a significant problem, what every TS owner will or already have faced with....
Still looking for the solution, next to the gearset syncronizing weak point
Anyway I like my TS very much, in spite of these questionable points
