OM 606 idle miss and excessive blue smoke
OM 606 idle miss and excessive blue smoke
(08-11-2020, 11:13 AM)zeemanwow...good to know. Thanks for following back up. Did you just throw a used one on there you found off ebay? Mine doesn't have the miss, but it does start to blue smoke even when it's 80F out. I can mask it with the glow plugs but I'm leaning towards the IP causing some delayed timing at lower rpm.zeemanI changed the injection pump and it runs fine now. There must have been a problem internally with the injection pump. Also eliminating the EGR made a big difference in performance.X Double Dot I actually idled it without the intake manifold off as I was looking for bubbles in the fuel lines. If it's coming from the turbo it guess it would have to be on the turbine side. I THINK taht is unlikely because the blue smoke seems to show up with the glow plugs shutting offI finally got my engine back together, along with everything I already did I have replaced the delivery valves and springs, rebuilt the injectors, changed the cam gear. It does exactly the same thing, a miss and excessive smoke at an idle.
I am at a loss of what to do next other then change the injection pump.
It seems that injection pumps rarely fail, it runs fine at high RPM.
