Never had this happen before -
Just need to whip an old n/a engine out of a defender so I can change the rear oil seal.
It's a low mileage early defender, very 'original' so was expecting a bit of a fight, but didn't expect it to win!
So all pipes/cables etc removed, all bellhousing nuts removed, hoist on - big heave - nothing
30 mins of effort later and still no sign of the joint splitting.
Plusgas round the joint, blowtorch all round the bellhousing to release any sealant.
