ISSUE
Some vehicles equipped with a 4.0L SOHC engine, with an engine build date of 04/01/2004 or earlier, may exhibit an oil leak from the rear of the
engine. The leak may be coming from the oil filter adapter, due to porosity. When the oil filter adapter leaks, the oil may wick around or follow the
ladder frame gasket channel to the rear of the engine. The oil leak may appear to be coming from the rear main oil seal and/or ladder frame gasket area.
ACTION
Inspect the oil filter adapter and determine the oil leak source, per Workshop Manual Section 303-00, prior to any repair attempts. If the oil filter adapter
is the source, replace the adapter. Refer to the following Service Procedure.
