This TSB article is being republished in its entirety to correct the front cover/water pump bolt torque values and the Front Cover Gasket Part Number.
ISSUE
Engine coolant may be leaking into the engine oil on some vehicles. The internal coolant leak may be difficult to identity. This may be caused by the
lower intake manifold side gaskets and/or front cover gaskets allowing coolant to pass into the cylinders and/or the crankcase.
ACTION
Revised lower intake manifold side and front cover gaskets have been released for service. Refer to the following text and Application Chart for details.
SERVICE PROCEDURE
NOTE
ONLY REMOVE ENOUGH ENGINE OIL TO DETERMINE COOLANT CONTAMINATION (THE REST WILL BE DRAINED AFTER THE
FRONT COVER REMOVAL/INSTALLATION TO FLUSH OUT ANY DEBRIS FROM THE FRONT COVER GASKET REMOVAL).
