Tools Required

WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.
  1. Clean the gasket from the crankshaft rear oil seal housing.
  2. Clean the crankshaft rear oil seal housing.
  3. Inspect the crankshaft rear oil seal housing for damage.
    NOTE: Do not use a sealant or adhesive when installing this component. Use of a sealant or adhesive can cause improper sealing. A component that is not sealed properly can leak leading to extensive engine damage.
  4. Install the crankshaft rear oil seal housing gasket over the bolts for alignment.

    Important:  The plastic inserts in the crankshaft rear oil seal housing are used to aid assembly only.

    The inserts are not required for service.

  5. Install the crankshaft rear oil seal housing. Hand tighten the crankshaft rear oil seal housing bolts.
    NOTE: Sealability of the rear main oil seal depends on the correct alignment of the rear main oil seal housing and the oil pan. Incorrect alignment may cause oil leaks.
  6. Apply engine oil to both sides of J 41349.
  7. Install J 41349 over the crankshaft. Twist the tool to aid in sliding the tool over the crankshaft.
  8. Place a straight edge on the engine block oil pan flange and the crankshaft rear oil seal housing flange. Use a feeler gage to ensure there is no more than 0.10 mm (0.004 in) step on each side. Rotate the crankshaft rear oil seal housing to make the step equal on each side. Replace the crankshaft rear oil seal housing if the rotation does not make the step equal.
    NOTE: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
  9. Tighten the crankshaft rear oil seal housing bolts.

    Tighten 

    Tighten the crankshaft rear oil seal housing bolts to 15 N.m (11 Foot lbs). Use J 36660-A to tighten the bolts an additional 50 degrees.

  10. Remove J 41349.

  11. Recheck the step height on each side to ensure the crankshaft rear oil seal housing did not move.

    If the step height is beyond specification, reinstall the crankshaft rear oil seal housing and measure the step again. Replace the crankshaft rear oil seal housing if the clearance is still beyond specification.
