OM 606 idle miss and excessive blue smoke
sub'd
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).
