I was just curious if there's a specified time when the injectors need to have their O-Rings replaced? Or any other indicators of needed O-ring replacement? I now have 250,000 on my PSD, is there any prescribed maintenance I need to address as the engine ages?

FYI.. I just converted to Rotella Synthetic Oil... Much easier starts in cold weather and engine seems to run smoother. Engine is a bit noisier with the synthetic.

 

Just keep up the routine maintenance and address any problems as soon as you notice them. I've got 281k on my stock injectors and o-rings.

 

ok, thanks
