So Fix it

Remove the valve covers with a socket wrench and detach the electrical connectors from the fuel injectors. Disconnect the mounting bolts for the crankcase-to-head tube assembly and remove the assembly from the crankcase.

Disconnect the oil rail from the engine. Push the electrical connector for the fuel injector out of the rocker arm carrier with a small pry tool.

Plug the oil drain holes next to the glow plugs with clean cloth. Disconnect the retaining bolt for the fuel injectors with a socket wrench and release the hold-down clamp.

Pry the fuel injectors from the engine with a Snap-On SDMT440 Torx tool so that you dont damage the fuel injectors. Discard the O-rings and copper washer on the fuel injector. Pull the cloth from the oil drain holes.

Mount new O-rings and copper washers to the fuel injectors. Coat the fuel injector assembly with clean engine oil and install the fuel injector. Attach the hold-down clamp for to the fuel injector and torque the mounting bolts to 24 ft. lbs. with a torque wrench.

Place the electrical connector for the fuel injector electrical into the rocker carrier. Lubricate the top O-rings on the fuel injector with engine oil.

Install the oil rail into the fuel injectors so that the mounting feet of the oil rail are flush with their mounting surface on the engine. Install three guide bolts to hold the oil rail in place.

Install six of the nine mounting bolts for the oil rail. Replace the three guide bolts with the three remaining mounting bolts. Tighten all nine mounting bolts to 10 ft. lbs. with a torque wrench.

Connect the crankcase-to-head tube assembly and tighten the mounting bolts to 60 ft. lbs. with a torque wrench. Attach the electrical connector to the fuel injector and install the valve covers.

Place an oil drain pan under each oil drain and open the drain plug with a socket wrench. Allow the oil to drain into the drain pan and replace the drain plug. This will prevent oil from entering the combustion chamber while you replace the fuel injectors.

Remove the valve cover with a socket wrench, and detach the electrical connectors from the fuel injectors. Remove the drain plugs on the oil rail and fuel rail. Disconnect the retaining screw for the oil deflector and remove the oil deflector. Remove the retaining bolt for the fuel injector.

Place the fulcrum of injector remover No. T94T-9000-AH1 below the hold-down plate of the fuel injector. Fasten the remover screw into the hole in the fuel injector plate, and tighten the screw to remove the fuel injector from the injector bore. Discard the copper washer.

Clean the injector bore of any debris with rotunda injector sleeve brush 104-00934-A and a clean shop towel. Lubricate the new fuel injectors with clean engine oil and mount a new copper washer onto the injectors.

Push the fuel injectors gently into the injector bore to seat the O-rings. Place the open end of injector replacer No. T94T-9000-AH2 between the hold-down plate and the fuel injector. Fasten the tool to the cylinder head with the retaining bolt from the tool kit. Tighten the bolt to completely seat the fuel injector and disconnect the tool from the cylinder head.

Install the oil deflector and tighten the mounting bolt to 108 inch-lbs. with a torque wrench. Tighten the fuel rail drain plugs to 96 inch-lbs. and tighten the oil rail drain plug to 53 inch-lbs. Connect the wiring harness for the fuel injectors and install the valve cover.

Disconnect the valve cover with a socket wrench, and unplug the electrical connectors from the fuel injectors. Remove the drain plugs from the oil rail to keep oil out of the combustion chamber while you replace the fuel injectors.

Remove the retaining screw for the oil deflector with a socket wrench and disconnect the oil deflector. Disconnect the retaining bolt for the fuel injector.

Remove the fuel injector from the injector bore with Injector Remover No. T94T-9000-AH1 and discard the copper washers. Loosen any debris in the injector bore with Rotunda Injector Sleeve Brush 104-00934-A and clean the injector bore with a shop towel.

Install new copper washers on the new fuel injectors and lubricate the injectors with engine oil. Push the fuel injectors into the injectors bore to seat the O-rings. Seat the fuel injectors into the injector bores with Injector Replacer No. T94T-9000-AH2.

Install the oil deflector and tighten its retaining bolt to 108 inch-pounds with a torque wrench. Replace the drain plug on the fuel rail and tighten it to 96 inch-pounds. Install the drain plug on the oil rail and tighten it to 53 inch-pounds. Connect the wiring harness for the fuel injector and install the valve cover with a socket wrench.
