Engine Oil Leaks - Fluorescent Oil Additive Method

Use the 12 Volt Master UV Diagnostic Inspection Kit to carry out the following procedure for oil leak diagnosis.

1. Add 29.6 ml (1 oz) of Dye-Lite® Gasoline Engine Oil Leak Detection Dye to a minimum of 0.47L (1/2 qt) and a maximum of 0.95L (1 qt) engine oil and fill through the engine oil fill. Thoroughly premix the gasoline engine oil leak detection dye or it will not have enough time to reach the crankcase, oil galleries and seal surfaces during this particular 15 minute test. The additive must be mixed well with oil and added through the oil fill. Check the level on the oil level indicator to determine what amount of oil to premix. If it is in the middle of the crosshatch area or below the full mark, use 0.95L (1 qt). If it is at the full mark, use 0.47L (1/2 qt).

2. Run the engine for 15 minutes. Stop the engine and inspect all seal and gasket areas for leaks using the UV Leak Detector Kit. A clear bright yellow or orange area will identify the leak. For extremely small leaks, several hours may be required for the leak to appear.

3. At the end of test, make sure the oil level is within the upper and lower oil indicator marks. Remove oil as necessary if it registers above the full mark.

Leakage Points - Underhood

Examine the following areas for oil leakage:

Valve cover gaskets Cylinder head gaskets Oil cooler, if equipped Oil filter adapter Engine front cover Oil filter adapter and filter body Oil level indicator tube connection Oil pressure switch or EOP sensor Turbocharger oil tubes

Leakage Points - Under Engine, With Vehicle on Hoist

Examine the following areas for oil leakage:

Oil pan gaskets Oil pan sealer Engine front cover gasket Crankshaft front seal Crankshaft rear oil seal Oil filter adapter and filter body Oil cooler, if equipped Turbocharger oil tubes

Leakage Points - With Transmission and Flywheel/Flexplate Removed

Examine the following areas for oil leakage:

Crankshaft rear oil seal Rear main bearing cap parting line Flexplate mounting bolt holes (with flexplate installed) Pipe plugs at the end of oil passages

Compression Test

1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the battery is correctly charged. Operate the vehicle until the engine is at normal operating temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs.

2. Set the throttle plates in the wide-open position.

3. Install a compression gauge in the No. 1 cylinder.
