SUMP OIL LEAKS

When investigating cases of oil leaks at the sump area the following points should be noted:

1. Oil leakage can occur from a number of points above the sump face joint and may give the impression that the flange joint is leaking. Oil can run on to the sump flange edge and flow along between the flange edge and stiffener to the small gaps between the stiffener ends, and then down on to the bottom face of the sump.

2. Attention should be given to the fuel pump flange joint, tappet chamber covers or their bolts and oil filter and joints.

3. On cars fitted with Power Steering a check should be made to ensure that oil is not leaking from the Power Steering oil pump.

4. Oil leaks do not occur at the sump flange provided that the sump joint is correctly fitted and the fixing bolts properly tightened.

Will you please bring this to the attention of all concerned at your location without delay.
