Just finished installing injectors from LDS, resealed all cups and adjusted the valves.. Fired it up and she purred like a big cat, no smoke. Waiting for the thermostats to open so I could top her off with coolant and go for a drive and BAM, she started missing and blowing unburned diesel out the tail pipe.Pulled the glow plugs and found number 7 wet with diesel, all the others were dry. Ran compression test and 7 is 0 psi. What could have happened? Carbon stuck under a valve, valve stuck because it went further down after valve adjustment? Any help is always appreciated.
