This sort of thing is so annoying but I suppose a bit surprising that it doesn't happen more often. After all theses little engines are supposed to be used.

I'd try a ring too. The groove can be formed quite easily in a drill chuck if a lathe isn't available, but first one needs to locate a suitable ring. Mersey Models engines use fibre packing (PTFE cord will do) but Mamod locos' uprated cylinders use silicone o rings. The 'high power' cylinders available for the regular Mamod engines simple have an oil retaining groove the increase the compression (may be worth trying that before packing the groove).

Personally, I'd go for a silicone o ring. Try this supplier, if you can't identify and locate the correct size from here ther's no hope!

Good luck!

Does the piston screw onto the con rod ?
If it does, you can fit a felt disc at the end of the piston & screw it all back together.
Hopefully you'll have it up & running soon, whichever repairs undertaken
Very Happy
