3406e smoking on startup

I'll pressurize the fuel line for the head tomorrow and see if it holds or leaks down

 

Pulled the injectors and blew compressed air into each cylinder with a rubber tipped air nozzle and have a very good leak coming from #2 exhaust valves. Also pressurized the fuel line going to the head and plugged the return and it would bleed down pretty quick. Kept pressure on it looking for leaks could never isolate it. some where between #2 and #3 injectors. Guess I'll be pulling the head. Fuel pressure at idle was 82psi and at 1200rpm around 92psi or so.

 

Rockers were off for the test. valves should have been fully closed. All other cylinders passed with no obvious signs of leaking (could have been but hardly noticeable). You could hear and feel the air and see atomized fuel coming out of exhaust port because I didn't drain the fuel before pulling injectors.

 

Could be injector upper o-ring or the injector itself. Of course probably could be a lot worse but I would start there
