Cams good heads good. Don't no what 2 do next

I reset it and it stays off for several months but symptoms remain consistant. I get a knock/rattle under load between 1500 and 2000 rpm. More pronounced in cold weather (under 45 *F). With rough idle it the colder temps until engine is warmed up.

Otherwise, it runs and idles well. I've taken the position that if it hasn't blown up in over 40k miles of use, this probably isn't fatal. Just did an 8 hour round trip this weekend with no issues.

I'd love to know if someone ever does figure their's out.

do a high pressure fuel system reset and Injectors

What does light diesel knocking sound like? I think I have it but I've been told normal on several instances. I've been around other similar year PSD and they didn't sound like mine so I've been wondering all along what the diesel knock sounds like. Googling just tells me nothing
