X Double Dot sub'dThe air temp doesn't seem to matter in my case. But you may have a point about it starting after the glow plugs cycle. It does take some time for the miss to start.
I have a similar issue, the blue smoke starts up after the glow plugs have kicked off (I have a light that is wired to the glow plugs which are on a i/o relay so I know when they kick off). It's very noticeable when it's below 70F out. It isn't noticeable when the engine temp is above 70-80F.
Do you think it is related to air getting into the injection pump/injectors and retarding the timing? The issue getting worse when there isn't a glow plug on to make sure the fuel burns?
(interesting to hear you replaced the turbo and it didn't make a difference, I was starting to wonder if that was causing it on mine).
I don't think it is a air in the fuel issue, I have replaced everything in the fuel system and there is no air bubbles in the plastic fuel lines.
I am going further and taking the injectors out and pulling the prechambers. I did see some bubbles around the prechamber ring on #5 when I had it running. I am also going to check the timing and see if the chain is stretched.
The oil drainback holes seem to be fine so that eliminates that possibility of the oil pooling around the rear valve .guide. I also noticed # 6 injector was not sealing well to the sealing washer for some reason. Going to clean everything up and reassemble.
Thanks Zeeman
