Hahaha bloody thing!!!
I got a big vibration at the end of the last session causing me to come in, it came on all of a sudden, like something let go. Box still drives and selects all gears, no bits in the oil, no burnt smell like the oil got too hot so hoping gearbox and bearings are ok and the vibration is from the clutch.
I have a borescope arriving tomorrow that I'm hoping will allow me to look in there and atleast get an idea of what's happened before Monday. What ever it is that's caused the gouges is hard cos a bit of gravel wouldn't do that.
