Hi,
I have a 998 cooper engine.
I posted a topic earlier today, regarding an oil leak ib the vicinity of the transfer housing bottom retaining nut (to the block).
I have just identified where the oil is coming from. It is from a hole at the bottom of the transfer case. This hole has a split pin which pokes through the hole.

Does this mean the crankshaft seal has gone and needs to be replaced? If so, please help as I have never done anything like that before! How easy is it for a novice?

Thanks

John

Yep the crankshaft oil seal has gone, best to sort it sooner rather than later if you don't want to be stuck by the side of the road with no drive to the wheels

To do it the whole of the drivers side inner wind needs striping down, probably not much on an earlier mini, clutch cover removed, two rear bolts can be a right to get at and remove and that side of the engine jacked up so you have better accesses. Remove flywheel and clutch assembly using a sutable puller and remove and fit a new seal using the special tool to be on the safe side, you can do with out, but best to make sure
Then back on with the flywheel/clutch assembly, cover and any other components that were removed earlier.

One thing I would recommend is while the flywheels off, you fit a new clutch as a precaution, as some of the oil that has leaked out from the seal may of found it’s way onto the clutch, contaminating it, meaning it won’t work as effectually as it should.

These is a complete guide in the Haynes manual if you fancy ding it your self or want to know what’s involved etc.

Hi
Thanks for the advice, I guess the hole on the underside is there to allow the clutch and flywheel assembly to breathe? I guess it also prevents the oil level in the housing to rise!

I think I will have a go at it myself, however I have to drive it home which will take over an hour!

I assume. the parts I will need will be the puller tools, clutch housing gasket, oill seal gasket. Also a lutch as you recommend. Anything else I would need to purchase?

Socket and long breaker bar for the flywheel bolt, torque wrench, oil seal remover and fitting tool to make life so much easer, other than that just the general normal tools, sockets spanners etc. oh and you don't need a gasket on the clutch cover as it’s not needed.

yeah this happened to me but i foind out from my clutch slipping in every gear! i think the bill i payed for it at a garage was £150-£200 that was with new clutch and all work done.

[JoeBodge]

what is the split pin for that is daggling out of the hole?

[1984mini25]

It’s a drain hole and the split pin, though it looks odd is there to stop C**p from getting inside.
