"Tuliped" intake valve. On cylinder number two causing a p0300 multiple misfire. Compression tested 0psi. Leak down test showed a faulty intake valve. Valve stretched so much that it would cause valve to stay open. Unbolted the rocker arm and valve would seal up on the leak down test. Noticed the heights of the top of the valves in this picture.
