Thank you!
Yes, indeed a unusual journey. It came to Norway early 2000's and has been used very little since then. Milage is only 44.000km...
The engine has been tuned from Middlehurst but also rebuilt approx. 10-12 years ago because of oil starvation from some previous owner in Norway.
I don't know why the thrust bearing failed, but my guess is because of wrong axial clearance on the bearing or faulty bearing... But, I also discovered the engine had an NISMO G-max spec 1 (silver cover) clutch installed. I think I have read somewhere that the pressure plates on these clutches have such high spring pressure that contributes to more wear on the thrust bearing. I'm I right?
