6.0L 7.3L Powerstroke High Pressure Oil System IPR Air Test Tool
6.0L 7.3L Powerstroke High Pressure Oil System IPR Air Test Tool similar to TU-32-7
Applications: 6.0L 7.3L Ford Powerstroke Engines
Includes 7.3L Powerstroke High Pressure Oil System IPR Air Test Fitting
One of the more common issues plaguing 6.0L Powerstroke owners are hard hot-start issues. These issues are almost invariably caused by leakage in the engine's high pressure oil system which operates the fuel injectors. Possible leakage locations include the high pressure oil pump itself, IPR Valve, STC fitting, branch tubes, standpipes, dummy plugs, oil rail ball tube o-rings, injector inlet seals, etc. If the leak or combination of leak sources is bad enough to prevent the system from building the 520 PSI required, the truck will not start under any condition - hot or cold. Locating the exact source of the leak(s) is the challenge.
The method most technicians use to locate the source of the high pressure oil leak is to connect shop air to the high pressure oil system by way of an adapter which takes the place of the ICP sensor. This method has several problems associated with it. First, the IPR valve is normally open and must be closed by either commanding it closed with a scan tool, or by using a stand-alone IPR driver tool or no air pressure will build in the system. (Connecting battery voltage directly to the valve will damage it.) Even when commanded closed, IPR valves are not designed to seal completely meaning that they will always leak some air during the testing process. Unfortunately, the sound of one air leak will make it difficult or impossible to locate other leakage points - especially small leaks toward the rear of the engine such as cracked branch tubes. Finally, the latest updated standpipes have internal check valve which prevent reverse flow - rendering the conventional test method useless.
Advantages With This Tool
- NO Scan tool or IPR driver tool is required - potentially lower tool investment
- Leaks of ANY size can be detected - because the IPR valve is removed from the system the fact that it never closes 100% and thus creates a distracting air noise during testing becomes a non-issue. In fact, it is possible to pressurize a system with shop air, close the shutoff valve on the tool, and leave the system pressurized overnight. We have seen systems that will hold the pressure until morning.
- No vehicle required - engine builders can quickly verify that an engine has no high pressure oil leaks before installing the engine into the vehicle where repairs are much more difficult
- Allows systems with the latest updated standpipes to be tested.
- This tool takes the place of the IPR valve meaning that the system can be completely sealed so that even the smallest leaks can be detected.
- The heavy-duty hydraulic hose is rated up to 5,300 PSI.
- Each tool includes three extra o-ring sets for the IPR fitting.
To connect, just remove the air cleaner, FICM, and coolant degas bottle (Turbo removal is NOT required). Remove the IPR valve and thread in the tool, hand tightening using the hose is sufficient. Connect shop air and listen for leaks. To locate the smallest leaks close the shutoff valve on the tool to seal the system. If desired a scan tool can be used to monitor air pressure in the system by observing the ICP sensor reading. This is not a required step. To prevent costly repairs we recommend air checking every 6.0L for high pressure oil leaks after any part of the system has been disassembled.
