I think I've found the leak (well, one anyway) in the main tank. It looks like the weld split at the top edge, several inches back from the front. Someone's tried a fix with some form of epoxy(?) but it seems to be porous.

That hole that is has been covered in siliastic I believe should contain a little screw to hold the breather in place. Mine was also covered in a horrible orange gunk, which seem seemed to result in more of a blockage than a seal, and thus oil leak down the block. My breather hose from this breather (on the rocker cover) is attached to the back of the air intake manifold (the flat end near the bulkhead). Yours appears to be plumbed into something else..?!

I notice that there is alot of oil on the side of the block - perhaps the rocker cover gasket is leaking also? Mine was and resulted in oil dribbling down the block onto the a hot exhaust manifold - a $3.00 gasket and job done.

Thanks everyone.

For clarity, the retaining bolt for the breather still exists, the silicone has been used to seal around the junctio between the top of the rocker cover housing & the breather. However, from the amount of oil on the breather either it hasn't worked, the joint at the edge of the breather base is leaking, or the bolt hole is leaking - there wasn't a gasket on the bolt, just that thread sealant gunk you can see in the photo.

Agreed, the rocker gasket may well be leaking. I have bought a spare in case.
I'll have a look at the manifold in the hope that the fitting is there for the breather hose. If not, I guess I'll be fitting one at some stage.
