Right Cylinder Head Check

WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 1996 Ford RV Cutaway, 1996 Ford Pickup, 1996 Ford F-Super Duty, 1996 Ford Econoline, and 1996 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform step 4) under CHECK PARAMETER IDENTIFICATION (PID) DURING CRANKING (if not already completed). Remove high pressure hose from right cylinder head. Using Fuel/Oil/Turbo Protector Cap Set (T94T-9395-AH), install appropriate cap on high pressure hose fitting on cylinder head. Using Oil High Pressure Leakage Test Adapter Set (D94T-6600-A), install plug into high pressure hose.
    WARNING: In the following step, engine may start.
  2. Install ICP/EBP Adapter Cable (D94T-50-A) between ICP sensor and sensor wiring harness connector. Connect a DVOM between SIG RTN circuit (Black wire) and ICP Signal circuit (Green wire) at ICP/EBP adapter cable. Observe DVOM and crank engine. Voltage reading should be 1-4 volts.
  3. If engine starts, or if ICP PID reading indicates 500 psi (33448 kPa) or more, an injection control pressure oil leak exists in right cylinder head. Inspect fuel system for oil contamination.
  4. If no oil is present in fuel system, remove cap and plug, and reinstall high pressure hose to right cylinder head. Remove right valve cover. Crank engine, and inspect injector body and injector bore area for oil leakage. Repair as necessary. If engine does not start, or ICP PID is still less than 500 psi (3448 kPa), perform LEFT CYLINDER HEAD CHECK .
