Oil Leak Diagnosis

When diagnosing engine oil leaks, the source and location of the leak must be identified prior to repair.

1. Add Rotunda Gas Engine Dye 164-R3705 or equivalent to the engine oil. Use 29.6 ml (1 ounce) of the fluorescent additive in all engines.
2. Clean the engine with a suitable solvent to remove all traces of oil.
3. Run the engine for 15 minutes.
4. Stop engine and inspect all seal gasket and galley plug areas for leaks using Rotunda 12 Volt Master UV Diagnostic Kit164-R0756 or equivalent. A clear bright yellow or orange area will identify leak. For extremely small leaks, several hours may be required for the leak to appear.
5. Service all leaks as required.

NOTE: For minor gasket leaks tightening the retaining bolts may resolve the problem.
