Took my 2000 Disco out a few weeks ago and since then I've had a leak between the engine and the transmission. Wondering if it's just the rear seal or should I do a pull the engine and verify everything.

 

Almost never the rear main (explanation here: https://landroverforums.com/forum/di...e2/#post711847), could be crucifix seals which can be replaced by dropping the pan, or could be the rear cam plug (assuming it is engine oil leak) which require trans or engine come out or it could be leaking from heads or valve covers or lower intake.

 

When I thought my rear main seal was leaking, it was actually either the head gasket, valve cover gasket, or intake manifold gasket. Replaced all three at once so not entirely certain which it was but it's now dry as a bone. Point being, it's most likely coming from somewhere up top and finding its way down to mimic the appearance of a RMS leak.
