Funny when I looked under drivers side, the wishbone, drive shaft etc is covered in oil other side is bone dry. Suppose at least they ain't going to rust.

However, the leak could also be (is probably) coming from the paper gasket under the cast-alloy holder for the crank seal, or the O-ring for the intermediate shaft holder may have failed (less likely).
You can access all of these if you remove the pulleys that hold the timing belt - make sure that you set the engine to TDC (top dead-centre) before you start.

Then better get studying the Haynes. How easy is it to change the paper gasket thingy under the cast alloy holder???
Cheers for the info.

The paper gasket is easy to change in itself, but there is a fair bit of stuff to remove before you can:
ensure the engine is at TDC at the crank AND cam - crank goes around twice for every one rotation of cam & intermediate shaft, so it's possible to only check the crank and have the cam 180 degrees out
remove the v-belt pulley wheel at the crank (4 allen bolts, 6mm, likely to be rusty, etc, so clean out the hex-hole well, to give your key the best chance to seat itself properly, and open the bolts with a sharp jerk, rather than just pulling hard, which will round out these bolts)
then you can remove the lower plastic cam-belt cover (last bolt is hidden by above pulley)
You then remove the cam-belt itself (ensure the engine is still at TDC at the crank AND cam)
You might then need to temporarily refit the v-belt pulley, so you have something to hold the crank with, while you open the large bolt to remove the cam-belt pully on the crank (or you could remove the starter and jam the flywheel teeth with a large, hard screwdriver)
Then you can remove two sump bolts and the other ones that hold the cast-alloy crank-seal holder (note the positions of the bolts as you remove them, some are different lengths)

What I can see is that the oil seal behind the wheel slightly protrudes out of the flange. Is this correct as I've pushed the bottom part of it back in but am struggling to do the same at the top. Please let me know. Could it be seemly that the oil seal has come out of the flange in which case I'm going to try and push it back in without taking the wheel off.
Also not sure how to line the TDC as the bottom fan belt pulley don't seem to have a noticable notch in it. to line up with the punch mark.
Look forward to hearing from you mate thanks for all the help.
