Way back in my collage days I found out the hard way that Hilmin Minx's didn't like being driven at ninety miles an hour for long periods. The engine droped a valve in #3, piston wacked the valve and smashed to pieces, the conrod and gudgen then wacked a large hole in the block breaking the camshaft into three in the process. I herd a loud bang followed by a rattly sounding engine still firing on #'s 1&2 then the windscreen was blanketed in steam. When I looked under the bonet the exhaust pipe was glowing enough to see the damage.
