551581 Adapter No. 511671 Adapter Notes: The air pressure applied during these tests must be at least 100 psi (689 kPa). When pressure is applied for the first time, it may take 3 5 minutes before the leak can be heard. This allows air pressure to displace engine oil in the Injection Control Pressure (ICP) system. The Injection Pressure Regulator (IPR) valve may need to be energized open more than once to completely clear oil from the ICP system. Once the oil is displaced, an air leak may be heard almost immediately after applying air pressure. An air leak on the high pressure oil pump shaft lip seal is normal during this procedure. This is not an indication of a high pressure oil leak, and the high pressure oil pump should not be replaced for this condition. Replacement parts may leak unless all surfaces are oil-saturated under system pressure and seals are seated during installation. cAuTION: To prevent personal injury, wear eye protection that meets ANSI Z87.1 and OSHA standards. High Pressure System Air Pressure Test cAuTION: To prevent equipment damage, · Do not leave the IPR valve energized longer than 120 seconds at a time. · Inspect adapter o-rings before performing these tests. Replace o-rings if worn, cracked, or cut. 1. Verify base engine oil pressure. 2. Turn the vehicle’s ignition to Key ON, Engine OFF. 3. Use a diagnostic tool (OTC No. 6764 or equivalent) to close the Injection Pressure Regulator (IPR) valve. 4. Apply shop-air pressure of at least 100 psi (689 kPa) to the high pressure oil system: 2003 2004-½ Vehicles: Use adapter No. 551581; remove valve cover to access high pressure oil port. 5. Use a diagnostic tool (OTC No. 6764 or equivalent) to open the IPR valve and allow the oil to drain. An air leak should be heard. Close the IPR valve. 2004-½ 2007 Vehicles: Use adapter No. 511671; use the Injection Control Pressure (ICP) location. Note: It may be possible to use adapter No. 511671 on 2008–newer 6.0L Econoline vans.
