yeah aware of the oil returning advantage, but with the short service intervals there will be on the drive train, i don't see this as an issue.

Nice to hear you have a similar setup, i will also have a separator between the engine and vented catch tank, and as mentioned planning to put the breather pipes from gear/diff to the catch tank as well.

going ahead and weld some aditional bungs for the catch tank then.

thanks again andrew
