They sent me a text friday and said it would be done today. I told them no hurry, take your time. They said they didn't have any issues. Shop in Anderson was new and very clean. They didn't look too busy. I hope the work matches the show. I told them I was very picky and wanted everything put back just as it left the factory. I would think the belt service is pretty routine, unlike your issue. They probably haven't seen very many NSX motors making noise. He very well may need some time to do his own research. I will post when I get it back. Good luck, keep us informed, curious as to what the noise is. I think those sticking LMA's may make some noise.
