The truck spoken about below is a 1982model 6.2L that I just replaced the heads on, and now I am getting excessive diesel smoke from just the passenger's side pipe and a real choppy idle. We had the injector lines completely loose to change the heads, so to bleed the injectors we removed the glow plugs and spun it over. While doing this all the lines got fuel, however a fuel mist seemed to only be pumped from cylinders 2,6,8 and cylinder #1 on the driver's side (and boy does is whistle under compression) once bled and turned over, I assume that was a fuel mist I was seeing, I still see air bubbles in the lines that connect inject to injector as over flow which seems normal. There is also a boat primer bulb connected inline from the tank before the primary filter on the intake, and this bulb looses a hard prime while the motor is running which doesn't seem abnormal....or is it? I noticed the main injector pump leaking from the throttle linkage before we purged the air however it has stopped, no fuel leaks to speak of.... Any ideas why one side would smoke excessively even at just idle vs the other? Thinking further into it the pass side was the one that blew the head gasket, both heads were replaced but if injectors 1,2,6,8 seem to be working thats only 4 of the 8 could the others be weak or damaged if they were the ones on the leaky side?? I did not keep track of which injectors came from which head. Also the bleed over lines from inject to injector are both capped at the furthest point(the firewall) is this correct? another observation is that when the two main plugs to the main injectore pump are unplugged there is no change in the way the truck idles or runs, this seems abnormal. I have a two pronged plug on the pass side in the loom with the glow plugs that seems not to have a home as well?
