If you encounter a diesel engine that exhibits excessive oil consumption, low compression or excessive blowby and you suspect stuck piston rings as the cause, the following procedure may be an effective correction:
1. Remove the glow plugs from all 8 cylinders.
2. Equally divide the contents of one can of top engine cleaner, part number 1050002, into each cylinder. (Allow the engine to soak for 24 hours).
3. Crank the engine with the glow plugs removed to expell the top engine cleaner.
4. Reinstall the glow plugs and start the engine.
