quote:I haven't seen a 6 fail yet but I have seen at least 3 5 cylinders this year with a rod through the side of the block. I can tell you the reason. "OIL" Or should I say a lack of changing it when recommended. All were sludged up with over 10K miles on the oil in the pan. Not one failed from being maintained properly. I did see one fail at 10 miles about 5 years ago when someone at the factory forgot to tighten the connecting rod bolts.
