1.9tdi possible engine removal

I've got one of the last 1.9 diesel (2010) Octavias with the BXE engine.

With 175,000 on the clock I can just detect the first signs of what I think is a dmf failure. Just on tickover, when it's hot there's some random metallic very light banging sounds coming from it. Obviously it will get worse so it needs doing. I plan to fit a solid flywheel as all the evidence suggests that this is a good move on the 1.9 with 5 speed manual.

It has had a small oil leak for about 5 years at the rear of the engine, very little but it just manages to wet the undertray, It is from the head/inlet manifold joint. Years ago I got a new gasket and started the job but the EGR pipe to the manifold has a frozen stud and I dared not risk shearing it as that would not really be repairable with he engine in-situe.

Anyway, I think you can guess where I'm coming from, Should I just pull the box and engine out as one unit and do both job? How much of a task is it over and beyond what pulling just the box is? I have a 4 post ramp and engine crane. Can I take the front crossmember off as a full unit with all the various radiators  as that would make access much easier? And comments, thoughts or suggestions please.

Many thanks.
