Piston cooling nozzle failure? Didn’t know that would throw a code. I would not drive until properly diagnosed. That nozzle fails, and you keep driving, your looking at an in frame.

I had that happen to me on a Cummins. Did the rod and main bearings and the tech knocked it off and didn't say anything about it. Got about 70 miles down the road and got a high crank case pressure code. Sad thing is had the work done at Cummins. Good thing is they backed it.
KB3MMX Thanks this. -
On edit: Just to note, these cooling nozzles are sometimes a mix of plastic and steel, with age and heat they do fail. So not always the mechanic. If you are getting in to the lower end, if possible, it is best to replace the cooling nozzles. They are located at the base of the cylinders, and shoot oil into the piston and cylinder from inside the block cooling the pistons. There are six of them and they use one bolt to attach.Last edited: Aug 17, 2018
