An engine oil leak may develop from the oil pump drive O-ring. This can often be confused with an intake manifold gasket leak. Careful inspection is required to determine the exact cause of the leak. Replacement of the failed 0-ring will commonly correct this concern.

    Bad oil leak. Pulled cover from converter, definitely not rear main seal. Looked at valley with flashlight, and there is oil as far as you can see both ways under the intake
