OM 606 idle miss and excessive blue smoke
My 98 E-300 which is my daily driver has been running fine, but all of a sudden when I start it in the morning and warm it up for a while it starts missing and blows out excessive blue smoke at any RPM. Sometimes if I turn the key off and restart it, it quits missing for a while.
It runs fine when started and then after about 10 minuets it starts missing and blows blue smoke. If I shut it off and wait 30 minuets and start it again it is fine for a while and then it starts missing and blowing blue smoke. If I start it and drive it right away it smokes a little going out the driveway and then when I get it out on the road it clears up and runs fine.
I come back and let it idle in a while it starts missing again and smoking excessively. The engine has about 185,000 and has been well maintained. No blow by.
This is what I have done so far with no fix.
1. Drained fuel tank and replaced fuel, cleaned strainer and blew out fuel lines
2. Replace all plastic fuel lines, fuel heater and all filters
3. Replaced DV washers and o-rings
4. Replaced injectors with rebuilt ones
5. Ran compression test 350 # 1-6
6. Replaced differential pressure valve and all rubber elbows
7. Replaced turbo had some oil in intercooler tube to intake.
8. Deleted EGR and did bypass in computer harness
I have noticed the timing chain is walking back and forth on the cam gear when running and looking in the oil cap hole, so I do have some timing chain wear.
Other then this I am at a loss at what to do next, I do have some new DV valves and springs coming to eliminate that.
Anyone have any other ideas, it almost acts like the oil drainback is plugged in the rear of the head and going down the valve guide.
Thanks Zeeman
I know this has been discussed on many blogs but none of them to seem to fit my issue.
