Good day from a new registrant seeking help from the home of the Rover.
Coming to your V8 door through a link given in another MG forum.

As a new surplus 4.6L Ford V8 engine/trans purchased here in the USA has finally been identified (via the MG symbol on the shifter) as built for the Rover, I would like to know the manufacturer or maintenance instructions (bleeding) for the single pipe hydraulic release bearing located inside the bellhousing. It has a green rubber bellows. Most of the MG parts sites don't seem to have much information other than part nos., especially pictures, as would be found here in the States.

The pipe is "floppy" when moved from outside the transmission and removing the tranny from the eingine is forseen as my only current option to check the connection of the pipe to the bearing. I've seen in some searching for MGs that this setup may be difficult to bleed (with what appears to be a bleed connector on the fitting outside the tranny).

Any help would be more than greatly appreciated before I crack the tranny loose.
