I'm just going to check the timing on my engine . . .

. . . I may be some time.



(Apparently it's 14 cylinder Bristol Hercules two-row radial sleeve valve aeroplane engine introduced in 1939.)

I bet it runs like clockwork

Perhaps a little noisier, not to mention smokier, than the average clock!

Yeah, maybe, but it's very pretty!

After rebuilding, the Fitter Supervisor, whimpered, “What do you mean you have a circlip leftover?”

yes amazing British engines. The sleeve valve means that the cylinder rotates to expose holes which form the valves. Hence the gears to rotate each of 14x2 sleeve valves. Note the 2 banks of 7 cylinders. The biggest radial piston engine with poppet valves was the 28 cylinder 4 bank Pratt and Whitney R 4360 (that is 4360 cubic inch) each cylinder with 2 spark plugs. With mechanical supercharger and power recovery turbines in exhaust would deliver around 4300 HP. So complex not the most reliable engines. ol'will

Better than trying to use toothed timing belts.

DON'T talk to me about those just now - the one on our XC60 D5 just snapped - £2k quoted to fix it

Wow! belt kits are only round £50 or a bit more with the water pump on ebay.
Have the pistons hit the valves?

4360 cubic inches is 71.4 litres in real money!

.. and ticks over beautifully.
