PS. i am not a dealer just because i have a huge collection of morris things. It's been my hobby for the past 25 years and the collection has come from salvaging parts that other people were throwing away at the time. I've been involved in restoring a large number of morris minors over the years and am a qualified mot tester. Not a morris dealer.
Ah right, sorry Brixton, I thought with you being an MOT tester that you would have your own garage and with you offering so many parts (even difficult early ones) and the odd car that you were a dealer. No offence intended
By the way, my comment about your cars not having leaks was not intended to be a commment on your ability as an engineer, but at the general leaky nature of the Minor!!!!
As for the gearbox cover issue, I have a few and they are all in pretty good condition, as has been mentioned previously probably due to the amount of oil sprayed over them over the years.
