There are a number of oil leaks from both transmission and the engine.
As delivered it was all pretty clean underneath, which changed quite a lot after the drive to the roadworthy.
However, all of these leaks have either diminished greatly or stopped with a bit more use.
A fuller examination is to be carried out after a good clean and another run to see which seals have swollen back to working specs and which need attention.
The right hand drive shaft seal almost certainly needs replacing. Some of the others may be safer left alone!
UPDATE
After another 30 – 40 kms or driving the underside is now pretty oil tight. There is a bit of weeping but no leaks as such.
