OM 606 idle miss and excessive blue smoke
blue smoke and misfire means it's getting fuel but not able to ignite it. To get reliable ignition you need a working injector that atomises the fuel well, you need a hot pre chamber and you need good compression.
I have seen this with bent rods and leaking valves as well as damaged prechambers. I'm sure there's more scenarios that can cause it.
