Crushed walnut shells should work just fine. It has in the past. As long as you don't load up the cats with the stuff. I think setting each cylinder to TDC would solve that problem. Anything that gets past the valves will just burn up in the cylinder or exhaust.
I think many people would be amazed on what works to fix cars. I knew a tech who would use plain old water in a cup and a vacum line and straw to suck water into the intake manifold with the engine running. You just want a sipp and not a gulp of water. As we all know water doesn't compress well in a internal cumbustion engine. The cold water would "shock" built up carbon off the intake valves.
