Meltdown? Like the valves were melting with the engine shut off? How is your chemical mix making it to the turbos and exhaust?
If you use chemicals you don't leave the fluid in the head before reassembling it. You pull the intake manifold, pour the chemicals in, let it sit for a while, then remove the fluid and clean out the broken up carbon. The engine shouldn't be run with any extra chemicals in it.
If you have a BMW you're lucky, they make a really sweet tool that gets hooked up to a media blaster and shop vac that fits the intake port in the head and seals it all off while you're cleaning it, so you all you have to do is blast, then suck out the walnut media and carbon with no mess.
