This evening I put my PS2 Ives 3236 tinplate engine on the track and took her for a spin for the first time. When going around the track theres a loud clicking noise that's coming from inside the engine. The clicking goes faster as it accerlerates. I tried to take the shell off the engine but it won't come off easily and I'm afraid of chipping the paint on the tinplate. Really strange that the shell wont come off easily. Any thoughts what could be causing the clicking?
