oil in Bell housing couple of questions

[A KIRK]

When I removed the engine I noticed there is a small amount of oil on the bell housing, it doesn't smell like gearbox oil. So I'm hoping its the crank seal.

I've not investigated that far yet, as I was only trying to do the gasket between the heat exchanger and the head, which resulted me in removing the engine.

So whilst its out I want to try and resolve the oil leaks. I have a lot of oil on the top of the engine and on top of the engine cover, which then seems to leak down through the drivers side of the engine. I'd assume if my crack seal had gone then it could be this being chucked around, however there doesnlt seem to be any oil on the outside face of the flywheel gearbox side.

Pic may or may not help


Could this oil in the bell housing be gearbox oil eventhough it smells like normal oil? if so whats the likely culprit?

Do the oil seals at the fan end often leak?

Thanks

More likely rear crank seal(s)
But to do them both while it's apart if there's any doubt, is not that much more trouble... ?

Don't know about often, but have heard of them being changed..

I'd suggest anyone changes the oil seal behind the flywheel when their engine is out as a matter of course... for the few quid they cost and the headache they can cause if/when they fail it's daft not to

Cheers guys, hopefuly its not the gear box, as I don't fancy taking that apart before Christmas

As I said, it is possible to put a new input shaft bearing in without too much trouble - its getting the old one out, and dealing with the oil thrower that's the worst part.
