Engine ID

Postby Ian » Mon Jun 19, 2017 10:11 pm

I would appreciate somebody IDing this motor for me. I believe it to be a Singer. it is 4 cylinder, open valve gear and pushrods. The casting number on the engine is SM20784A and the engine no. is 54481 with a small J above and between the 5 and the 4. The radiator is badged Marston Excelsoir Ltd Wolverhampton MKV11 Radiator block no 26820. The Magneto with it is a Lucas with a chain drive but just viewing from the outside the original may be gear drive.

not sure how the pics work.

Radiator is pretty much a standard item fitted to many UK cars with thermo siphon cooling up until the 1950s
The engine however started life a long way from Coventry, almost all gasoline engines used a side valve arrangement and I have only seen OHV open valve gear on stationary engines, they had an open crank too.
I assumed it was pre 1920 and an hour of web search solved the mystery, there was one manufacturer who pioneered the OHV principle and obtained a patent in 1904. It is interesting to see the evolution over just 5 yrs
from 1913 we have

There must have been a lot of hot oil evaporating from the cylinder head and they probably introduced a rocker cover fairly soon afterwards, nearly forgot maker was Buick.
