[TR] TR4 oil leak (dave)

[Q]

Not not plug that hole.  It is the drain hole for the bell housing.  No doubt that your rear main scroll seal is leaking a bit and finding it's way out there. 

If you plug the hole you will just fill the bell-housing with oil though I doubt it is "Water tight" enough to do so.  Thought it might fill enough to touch the flywheel edge and make a mess, not to mention an oil soaked clutch plate.
