I sometimes think my biggest Boo Boo was buying my first Model A. It's a "mistake" I have repeated a few times - slow learner!
This, by far is my worst. I had one of my As in a shed in the back yard. The shed was on sloping ground and the car was parked nose down on not a very steep incline. The engine hated running cold so I decided to let it idle for a while before reversing out of the shed. By the time I had driven 100 meters, I could hear a bearing knocking. Disassembly revealed a ruined rear main bearing. The oil in he valve chamber overflowed onto the timing gears before it reached the rearmost gallery, hence starving the rear main bearing of oil. The dipper tray on No 4 had also emptied quickly, leaving the rod bearing short of oil.
The engine is now back together with new main bearings and a new rod bearing in No 4 and my back account is much lighter.
I'm reluctant to click "Post Quick Reply" on that one!!
