3. Important: Always install a NEW oil pan gasket.
The oil pan gasket and oil pan must be installed and the fasteners tightened while the adhesive is still wet to the touch.
Install the NEW oil pan gasket into the groove in the oil pan.
4. Important: The oil pan alignment must always be flush or forward no more than 0.3 mm (0.011 inch) from the rear face of the engine block.
Install the oil pan onto the engine block. Press the oil pan gasket into the grooves of the engine front cover and crankshaft rear oil seal housing.
5. Slide the oil pan back against a suitable straight edge.
6. Install the oil pan bolts and nuts, but do not tighten.
7. Measure the pan-to-transmission housing clearance using a feeler gage and a straight edge. Use a feeler gage to check the clearance between the
oil pan-to-transmission housing measurement points. If the clearance exceeds 0.3 mm (0.011 inch) at any of the 3 oil pan-to-transmission housing
measurement points (1), then repeat the step until the oil pan-to-transmission housing clearance is within the specification. The oil pan must always
be forward of the rear face of the engine block.
