So the numbers matching engine for my 68 RR that I am restoring was rebuilt by an excellent engine guy a long time ago. How long I have no idea. My best guess is probably 15 years or maybe longer. Anyway I took my endoscope and looked at all cylinders and in at the cam. It’s clean as a whistle. I was told that they turned it every so often and they sprayed fogging oil in the cylinders. It turns freely. It may be another couple years before my car is done. Part of me wants to disassemble it and make sure everything is good and part of me wants to put it on a stand and run it as good as it looks. If I go that route would you put some oil in it now and prime the pump to pump it through the engine or just wait until it’s about to be ran? Any benefit to circulating oil through it every six months or so? I pull the plugs and turn it over every few months now. Pics are taken with my endoscope. Engine is fully assembled. Thanks for the advice
