Propshaft BW35 Gearbox

[Tonythestag]

I'm stuck can someone help me if possible. Gearbox oil is seeping out of what looks like to be a core plug at the end of the splined yoke! Is it possible to seal this or will I have to replace the yoke? I am obviously worried about any sealing compound contaminating gearbox oil.
Many thanks
Tony

I had my prop shaft rebalanced years back and the yoke was part of the shaft. Doesn't it just slide intot eh gearbox? I don't recall any oil coming out of the gearbox when I remove the shaft.
