HI im new to the forum so here goes.
Ive just got a GTi 16 V '96 106K miles and though its a rocket there is a worrying oil leak from the crank seal on the gearbox side.

Is it a big job, engine out? or am i ok, im a fairly competent tractor mechanic!!! different technology i no but the principles are the same.
Any advice gratefully recieved.
Warby
