Introduction
The valve housing may crack causing certain remanufactured fuel injectors to malfunction.Problem
Some remanufactured valve bodies on fuel injectors have been cracking under high pressure. This crack in the valve body can cause fuel to get into the engine oil.Solution
All 10R-0957 Injector Gp Fuel with serial number range 848368 to 850132 should be removed from the parts stock. 10R-0960 Injector Gp Fuel , 10R-0961 Injector Gp Fuel , 10R-0963 Injector Gp Fuel , and 10R-1268 Injector Gp Fuel with a serial number range from 188029 to 188914 should be removed from the parts stock. The above listed fuel injectors should be removed from the parts stock and the injectors should be held pending further instructions.
