[Terry Burtz, Calif]

I had a pilot friend that owned a Funk airplane.

The Funk used a Model B engine that was dry sump and inverted (cylinders down).

He changed the valve chamber gasket and went for a test flight.

Upon take-off, the oil pressure gauge was pegged (lots of pressure).

Just as he cleared the end of the runway, the engine started to clatter.

Luckily, he throttled back, circled and landed without incident.

Turns out that he forgot to poke a hole in the valve cover gasket that would feed oil into the galley that provides oil to the mains and camshaft.
