OM 606 idle miss and excessive blue smoke
yea I've been meaning to do a compression test, i just know it's going to cost me a bit to buy a tester with the right threads etc. when I had the pan off the cylinder walls all had good cross hatching, but that doesn't mean the rings (and valves) were actually sealing.
Let me know how your prechambers look, i've been suspicious about those as well but again have been holding off due to the tools etc that would be needed. That said I'd prefer to replace those over pulling the head.
I'm similar to you in that I've rebuilt and reshimmed the injectors, redone the fuel lines, replaced the glow plugs and still have the issue.
