On reading further it seems on the Schneider trophy plane it was necessary to change a piston. The rules forbade engine removal; the plane was tilted to bring the block vertical.
Apparently under war service conditions blocks were often changed at the V angle!

Oil consumption at max cruise 10 to 18 pints per hour. ..
