LOL!!! Yes that is one of many on the list. Backwards threads on the rear of the crankshaft and an Oil Slinger Plate just aren’t the same as a Rear Crank Seal.
Even Rolls Royce up till 1980 had the Oil Slinger/backwards thread on the Rear Crank Shaft. After that they put a real seal there.
IIRC the Spitfire 1500 they placed the Fuel Pump directly above the Distributor. More than one burned to the ground due to the Fuel Pump going bad and leaking on the Distributor sparking with gas dripping on it.
Right up there with V-12 Jaguars with leaking Fuel Injector lines spraying on the Distributor in the center of the valley. Can you say Flash Fire Kitty ?
If you are a good boy, maybe she’ll leave it ti you
