how much roughly am i looking at to get my gearbox overhauled? sounds terribly like the layshaft bearings have given up the will to live, start it up from cold get a nasty knocking noise, put the clutch down noise stops, clutch back up and noise comes back. seems to go when it's warm though.

utterly pissed off with the whole thing now after spunking over 4k rebuilding the engine last year and now this i'm just trying to weigh up spending more on it or locking the garage and forgetting about it for the rest of the year.
