Yes, I used the finest grit auto supply stores offered for valve grinding car valves. I can imagine your shocked tone of voice in your typing. I took the advice of a fellow who also had a Steamlines Shay with osimotor. Iran it on low 5-10 psi for 1 minute before cleaning and testing under steam. By the way, I cleaned the entire motor disassembled, before reassembling and attempting steaming. I had to repeat the process a total of two times to get the assembly to seat and not leak steam. It used to leak more steam than the exhaust. I have no machinist experience. Someday, I hope to take classes or work under the direction of the local model machinist group. I just need more time. ~ Gary - Steaming over Terror Trestle

Do I misunderstand, or did you actually ran the engine with valve grinding compound in the valve chest? What grit was the compond you used?
