Diesel fuel in oil

I have a 2001 Chevy Silverado 2500 HD 6.6, I have diesel fuel in the oil, this is the second time. The first time was in 2009 I put all new injectors, And they said it was an O-ring on the fuel rail. This is happened again to days ago I donít know what the hell to do. I only have 134,000 miles on it. Please give me some pointers so I donít lose my truck.

Thank you

Welcome to DieselPlace
I moved your post over to "Duramax First Generation: 2001-2004 (LB7)" for better views and responses to your issues

Is there any mods done to your truck? ( ie. lift pump, tune, exhaust, etc...)

Sounds like a cracked body on an injector to me.
