Where are the brass bushes?
Regarding the original leak the small o-ring inside the mainshaft was slightly damaged and worn and the oil guide pin (pic attached) was broken. I'll replace the o-ring and the clutch push rod oil seal (think its called o-ring 8216) anyway. But what is the purpose of that pin? I'll get myself a manual soon. I expect the engine is coming out, although it clearly had been recently split and the cam chain is certainly new.
