Currently the engine is sitting on a shelf waiting attention. As I know it will be the biggest sink for my budget, I am delaying the inevitable a bit by waiting.
Aside from rings, bearings and general service, I am hoping that there will be no surprises once inside. Cosmetically, there are several damaged fins on the engine that will need to be repaired.
The Ariel club of USA manufactures new con rods for this engine. They are high quality albeit eye watering expensive. Knowing that the rods that are in there are 60 years old, I know that they will be something that will be worth getting for peace of mind.
Likewise, Morgo in the UK makes a high-volume aftermarket oil pump for this engine. That is also on the wish list.
