Pistons did not have any damage and the rings looked good up close visually I guess you have to look at them up really close and look for pitting. I did do all the work myself and purchased this exact ball flex hone. I tried to buy rings for the top but they had to be custom made. Just re-used them with 42k miles on them. BUt keep in mind when doing all that work, you have to press out the cylinder liners and reseal them. I ordered the tool from a UK Lotus vendor, then I ordered the liner sealant from JaeParts. It took me 1.5 years from start to finish. Parts sourcing, machine shop re-work of the crank and head surface, and buying tools I didnt have. It was a lot of work for which I was quoted $25k in California. Thank you for the great communication your answers are helping me alot, I have bought parts in the past from JAE did you replace the other piston rings and just reuse the top? your compression numbers were really good after your rebuild.

Kent I only tried to order the top ring from Total Seal but the sales person was unmotivating when I mentioned Lotus. I kept all the same rings and never removed them. If you engine technically still runs and idles normal then A simple compression check should put you at ease. Quote Link to comment Share on other sites More sharing options...
Joey4420 Posted December 26, 2021 Author Report Share Posted December 26, 2021 Well I have an update to my engine. Everything but the physical heads and block being replaced. Valves, cam, crank, rods, pistons/sleeves, and everything in between. The big news is one head has already been installed so soon I hope I should hear a running engine.

alanlambert Posted December 26, 2021 Report Share Posted December 26, 2021 Looking good, Do you have all the parts to complete the re assembly now ? Quote Link to comment Share on other sites More sharing options...
Joey4420 Posted December 28, 2021 Author Report Share Posted December 28, 2021 All the parts are in stock and hopefully it will be done in the next few weeks. The shop I use doesn't dedicate time to the engine building, so he does my engine when nothing major is in the main shop, it is a Lotus dealership though and he has built several Esprit V8's so I trust his work.
