Recommended Procedure:

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Ford RV Cutaway, 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Smoking or open flame of any type must not be present when working near fuel or fuel vapor. Failure to follow these instructions may result in personal injury.

Check for the correct oil level using the dipstick with the vehicle on level ground. If there is no oil or very little oil in the crankcase, the injectors will not operate.

If the oil level on the dipstick is overfull, it is possible the engine was incorrectly repaired or fuel/coolant is diluting the oil and filling the crankcase.

Inspect the oil for color. A milky white oil indicates possible coolant contamination and will have an ethylene glycol odor.

Oil contaminated with diesel fuel has a diesel fuel odor and increases the engine oil level. If the engine oil level is above Max due to diesel fuel dilution, the oil appears thin and watery.

If the oil level is overfilled, drain the oil and the fuel filter housing. Isolate either cylinder head by removing the corresponding fuel line from the fuel filter housing. Remove the fuel pressure test port plug from the secondary filter housing. Install the plug in the outlet port. Install the Fuel Pressure Adapter (303-765) and Gauge 0-1.1 MPa (0-160 psi) Bar 014-00761 or equivalent at the test port to confirm constant fuel pressure.

Using the scan tool, access output state control (OSC) and command the fuel pump ON. Watch for fuel to drain out of the oil pan drain hole. Depending on the severity of the leak, it may take some time before a leak is noticeable. Remove the valve cover at the suspect cylinder head and inspect the injector area for leaks.

Check the maintenance records for correct oil type and viscosity for the vehicle operating temperature. Single weight or 15W-40 oil is not recommended for cold ambient temperatures. 10W-30 oil is recommended for cold ambient temperatures. Oil that has had extended drain intervals has increased viscosity (become thicker) and makes engine cranking more difficult and starting less reliable at temperatures below freezing. Refer to the lube oil chart or Owner's Literature for the correct oil selection for temperature conditions.
