J35A7 Engine

Camshaft, Rocker Arm Assembly, Camshaft Seal, and Pulley Installation

Front
1. Apply a light coat of oil around the camshaft oil seal.
2. Gently tap the new camshaft oil seal (A) into the cylinder head.
- 1 Tap the camshaft oil seal in squarely.
- 2 Install the oil seal about 0.5-1.5 mm (0.02-0.06 in.) below the surface of the cylinder head.





3. Insert the camshaft (B) into the cylinder head, then install the camshaft thrust cover (C). Always use a new O-ring (D).
4. Check that the oil seal lips are not distorted.
5. Install the solid dowel pins (E) and the hollow dowel pins (F).
6. Loosen the valve adjusting screws.
7. If the rocker arm assembly is disassembled, reassemble the rocker arm assembly.
8. Set the rocker arm assembly in place, and loosely install the bolts. Make sure that the rocker arms are properly positioned on the valve stems.
9. Tighten each bolt two turns at a time in the sequence shown to ensure that the rockers do not bind on the valves.





10. Install the injector base (A). Always use a new gasket (B).





11. Apply new engine oil to the threads of the camshaft pulley mounting bolt (A). Install the back cover (B), then install the camshaft pulley (C).





Rear
1. Reassemble the rocker arm assembly.
2. Loosen the valve adjusting screws.
3. Apply a light coat of new engine oil around the camshaft oil seal.
4. Gently tap the new camshaft oil seal (A) into the cylinder head.
- 1 Tap the camshaft oil seal in squarely.
- 2 Install the oil seal about 0.5-1.5 mm (0.02-0.06 in.) below the surface of the cylinder head.





5. Insert the camshaft (B) into the cylinder head, then install the camshaft thrust cover (C). Always use a new O-ring (D). Apply new engine oil to the journals and cam lobes.
6. Check that the oil seal lips are not distorted.
7. Remove all of the old liquid gasket from the rocker shaft holder and cylinder head.
8. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0002, 08718-0003, or 08718-0009, evenly to the camshaft holder mating surface of the cylinder head.

NOTE: Do not install components if too much time has passed after applying the liquid gasket (for P/N 08718-0002, no more than 4 minutes, for all others, no more than 5 minutes). Instead, remove the old residue and reapply liquid gasket.





9. Set the rocker arm assembly in place, and loosely install the bolts. Make sure that the rocker arms are properly positioned on the valve stems, and the dowel pins in the rocker shaft bridge are properly positioned to the cylinder head.
10. Tighten each bolt two turns at a time in the sequence as shown to ensure that the rockers do not bind on the valves.





11. Install the injector base (A). Always use a new gasket (B).





12. Apply new engine oil to the threads of the camshaft pulley mounting bolt (A). Install the back cover (B), then install the camshaft pulley (C).
