Wow i been a mechanic for 15 years and I never heard of a diesel engine failure due to this
Its not a 2 Stroke!
Again 5 min of idling will not hurt the car!!! My duramax has an elevated idle feature for warming up. maybe I need to do this so it idles at about 1000-1200 RPM.
This makes me laugh I have let all of my diesels idle in the morning to warm up (including my TDI's) and they have all are living longer than 300k. You people worry too much!
