Bought an old valve off eBay, removed the top and used the bottom to pour B12 Chemtool liquid. I created a metal gasket to block the liquid from going into the front side of the engine. Since the rear passages were fully blocked, I just filled the valve with B12 juice and kept it filled for a few days, occasionally pushing the liquid with a 100 PSI air-hose. After a few days and the blockage still present, reassembled the original valve and hose and tried to start it. It took two days of repeated attempts to start until eventually some liquid came off the tail pipe and started. Took it for a fast run on the freeway and eventually the computer cleared the permanent code that had been set over the last two years.
