Morris Minor Owners Club

The rear of the engine leaks oil.
On the technical pages it states 'Owen Burton now does a replacement oil seal kit to sort this out' - Who/What is Owen Burton and how do I buy a replacement seal kit. I have tried to Google Owen Burton but not come up with anything.

£60 seems a little pricey tho

How bad of a leak is it? If its within average british engine leakage then i would say just leave it alone. If it is a big leak then you should also look into why it is leaking so much.

these leak when there is 'fume' pressure in the block forcing oil past the v simple 'scroll' seal. Can also be because the main bearings are badly worn - and excessive oil is blasting at the seal. Cure the pressure and/or the main bearings and the leak should resolve.
How to cure pressure - well it may be needing a rebore and new pistons and rings - or it may just be that the breathers are all choked up - so check them first - and make sure one is connected to the carb so the engine draws the fumes in - and burns them ! Check by taking the oil filler cap off when hot and idling - if there is a plume of fume - you have found the problem. i believe the fancy rear seal has a mixed press for effectiveness - better to sort the problem rather than try to hide the symptom.

Also check the oil is indeed coming from the rear of the engine. It is common to have a timing cover gasket oil leak, and the oil gets blown back along the sump and drips at the rear.

Don'#t bother with the add on seals. To fit them requires an engine out plus machining that is beyond most home workshops. The seal also requires very specific crankshaft dimensions, and won't work on many - but you won't know until you've got the engine out and the flywheel off.
