New Project (to go with the old one)

Coke contains phosphoric acid whics is good at dissolving rust, but if left long term would cause more damage than good, so if you are back in hospital soon, I'd suggest something oily rather than acidic.
Hot water would only help, IMO.
 
Excellent idea using the torx bits on the broken plug Ricahrd. Though I've never had one snap on me, I have certainly heard of it happening to others.
 
That engine looks quite modern for a 60 y.o lump or maybe it's me getting old
Is it overhead inlet , side exhaust like a P4 /P5 ? Certainly "crossflow"
Why not fill the bores with diesel ? Cheapish and penetrating and you'll get a lovely smoke cloud when it fires up
 
It's a strange design, overhead inlet valve, sidevalve exhaust. Exhaust valve rockers are under the cover you can see below the exhaust manifold, cam acts on them directly, with pushrods going up past the exhaust manifold (inside the two lumps you can see on the side of the head / rocker cover) and operate the rockers for the inlet valves in a fairly conventional OHV way.

Despite how it looks, the engine sits vertically, the head is mounted at an angle, making room for the side exhaust valves.

Same engine was used in early Land Rovers, in fact this a recon one from a landy and was fitted with the P3 specific bits. They also did a 6 cylinder version in the 75 model.
 
It is strange design. I'd love to know why Rover went that route, as their pre-war engines were quite good. It was fashionable in the US at the time and was used on by Willys (aka Jeep) whom Rover would have been studying quite closely for the Land Rover. I strongly suspect that in the US it was simply a cheap way of modifying an all side valve engine to have at least some overhead valves! I understand the engine type as a breed do run really smoothly though, so perhaps that was what impressed Rover.

What are you thinking of fitting instead, Rick? Please don't say T16 - the poor old axle will vanish in a blur of axle tramp and flying spring leaves! And punch a hole in the boot floor with the unsupported end of the springs too!
