Review on Duramax Diesel Injector Installation Install by Roy Bush

Installed with no problems. Spare parts are good, I will buy more. This was the second valve cover removal on the injector replacement project as the truck started producing "oil", an additional 4 liters per 1500 miles. Added replacement of return and pump of CP3 injector within the 2nd round. The problems have been fixed. I would add new return lines to the injector replacement project to avoid future problems like mine on the LB7.
