Seems to leak badly when lowering the front shovel.

Have you got a leak on the return to the tank?

Pete.
It leaks ONLY on that valve spool shown on the picture.. the One on the left SIDE of the valve spool assembly...
It ONLY pours out oil when the front bucket is coming down

The first and rather obvious comment is that the valve shouldn't leak and clearly need repairing.

The simplified diagram below shows the common links between the front and back.

If it is actually a spool leaking then it will likely need replacing.

I can't really make out much in the photo and I am not familiar with the set up but are you sure there is not a union weeping on the return line?
