Rolls-Royce 20/25 engine rebuild

After another long delay I have been doing some work on the Rolls-Royce 20/25 engine that I've been rebuilding. I wanted to find a better way of replacing the cam follower rollers and pins and so had a tool made to hold the follower securely as the fork tends to bend and pinches the roller. This was ready last week and it worked beautifully, all cam followers are now rebuilt and fitting them allowed the installation of the cylinder block. With this on I could assemble the new pistons to the connecting rods and they are now fitted to the engine. I've ordered the 5 short cylinder head studs that run down the middle of the block as those that came with the engine are no good, I've also made a start on cleaning up the cylinder head, hopefully this will be back on by the start of next week. That just leaves the sump, some new oil level floats have been ordered, and with that done it'll be a lot closer to going back into the car.
