Thanks Ferret. I have had the secondary drain mod fitted.

Just to close this one out.

the final fix was a full gearbox rebuild - in DArwin, but through AB in Victoria. Total cost $7860

Yes that hurt.

Prettt much, The list of things I’ve done in the last four months is very large - it’s going to be a brand new car soon, was going to sell it for a new one but may not have to now!!
