I'm hoping someone here will be able to help me out. I've just noticed a "second" seal on the back of an EA81 crankshaft. There's the usual one then between the bolt holes and the flywheel centring ridge is an orange seal.
My local parts joint only have one number for the EA81 rear main seal. Do I need to replace this orange seal or just leave it? It's not leaking but while I'm in there it's usually worth doing.
Any insight or thoughts on this appreciated.
