Horrible. They said they would diagnose my truck, so they diagnosed it and took it apart, with out my permission to take it apart. Just test it at no charge. I asked them for my truck and they were like it’s not drivable we took of the valve cover and push rods. He refused to put my truck back together unless we paid him 6 hours of labor or fix it. Now my truck is in pieces, thanks to them and for sale. Thanks J and R.
