Wretched Roadster - Surprise #2 in a Series of ?

[David in San Antonio]

After removing the pedals and pedal shaft as covered in Surprise #1, we pulled the engine. It had been leaking oil from the flywheel housing past the cotter pin, dropping a quart per 20 miles or so. Also it was making a disturbing clanking sound. When we removed the pan and dipper tray, there were, as expected, bits of the chewed up fiber timing gear, lots of sparkly silver bits of babbit, and a healthy dose of grit. And also a surprise mystery: a nearly-complete circle about the diameter of a quarter, made of heavy wire. A retaining ring? A stray scrap that fell onto the engine unnoticed? Or worse, noticed but not retrieved?

The Answer:
A bit of head scratching and finally identified it. The bottom of the oil pump spring had snapped off. I wonder how long it had been sitting there, and sure glad it broke off below the dipper tray.

Also a bonus surprise, though not a big one: the serial number on the block indicates it’s from 1928.

Stay tuned for more surprises.
