"It would jam, and bits would fall off."

Reminds me of my college days Austin bugeye Sprite. Got oh, say, about 20 miles per quart of oil. Electrics by the Prince of Darkness - Lucas. The hood had the endearing trait of sliding right off the car if you came to too sudden a stop. This provided endless entertainment at busy intersections.

The last Limey I owned was a 72 Norton 850. It shook so hard at idle that various pieces would loosen and come off...like the carburetors. The valve stem seals had failed to the point that, at cold start-up, engine oil would shoot out of both exhaust pipes and cover the turn signals.

Ex had a TR-6 and earlier model TR-3? Anyway, oil filter had to be placed inside a can, rubber seal/gasket placed on opening then one had to shove this contraption down through a tiny space, being careful not to misalign gasket while threading in place. If not done exactly ride? Oil would pour out.

Perhaps the same idiot that designed this went to work for firearms industry after TR went out?
