Mr Hupp has been coming to B&B for years and we are sorry his last experiance was not a pleasant one. The cylinder repair kit we tried using did not seat and rectify the problem. We let Mr Hupp know that it may or may not work and that he may want to take it to a machine shop. He instrusted us to try. We have used this kit on several other customers vehicles with mixed results. After this issue, we will no longer be doing any repairs for blown plugs in the future. Losing good customers is not worth it to us. I asked Mr Hupp what if any compisation he wanted and he did not request any at that time. He was charged only for the parts and .5 hrs labor and is curently using the coil purchased and installed at his last visit. Mr Hupp should feel free to contact us at any time for any further concerns.
