Its possible to have that happen if you were running pig rich... and the oil became contaminated with fuel..
Usually when you have a Code 41... The PCM will revert to the last known good learned fuel values... and it will try to run off that value.. and chances are you may be a bit richer too..
And Trust me, even my L36 gave me no warning... It just happened.. Was moving along and then suddenly I could feel the motor start binding a bit... Looked at the oil pressure and did the " Oh ****, Not Good " thing... By that point it was too late, the signs of a Knock were present.. we took it apart and found that it had spun the #4 rod bearing.. The sad part was the car the motor came from had 90k on it, and the Motor had a Reman Tab on the side of the block
, it still spun that bearing..
I still know how you feel man..
