CAUTION: Before removing the cylinder heads, allow the engine to cool down to room temperature. Never remove a cylinder head from a hot/warm engine. The cylinder head may warp.

NOTE: When removing the cylinder head, the exhaust manifolds must be removed from the cylinder head. Install the exhaust manifolds AFTER the cylinder head and gasket have been installed.This is to prevent damage to the cylinder head gasket tabs.

LEFT CYLINDER HEAD (ENGINE INSTALLED)
1. Disconnect the battery negative cable.
2. Drain the cooling system. Refer to Cooling System/Service and Repair for procedure. Service and Repair

3. Remove the intake manifold.. See Intake Manifold/Service and Repair. Service and Repair

4. Remove the exhaust manifold(s).
5. Remove the cylinder head cover(s).
6. Remove the spark plug wires from the sparkplugs.
7. Remove the distributor cap, rotor and dust shield.
8. Turn the engine until the camshaft dowel pin is towards the top of the engine.

NOTE: The timing chain must be held in place and not allowed to drop down when removing the cylinder head. If the chain and sprocket slip, the timing case cover must be removed and the timing chain tensioners released.

Fig. 14 Camshaft Sprocket Support Special Tool 7317:

9. Use tool 7317 to support the camshaft sprocket and chain while removing the cylinder head cover. The tool consists of a support bracket and a dummy bearing Fig. 14.
10. Remove the bolt and adjusting lever from the bracket(s). Place the bracket on top of the timing case cover. Use two cylinder head cover bolts to mount it.
11. Thread the adjusting lever bolt through the bracket(s), the sprocket and into the adjusting lever, finger tight.
12. Pull the adjusting lever up tight. Tighten the adjusting lever bolt.

Fig. 15 Positioning Special Tool 7317:

13. Loosen the camshaft thrust plate bolt. Pull the thrust plate up and away from the camshaft.Tighten the camshaft thrust plate bolt Fig. 15.
14. Remove the timing case cover to cylinder head mounting bolts.
15. Place a socket or wrench on the crankshaft pulley nut to prevent the engine from turning over.
16. Loosen the camshaft sprocket bolt.

Fig. 16 Rocker Arm Shaft Assembly:

17. Loosen and remove the cylinder head bolts. Remove the rocker shaft assembly (note that the caps are pinned into the head and will only go on in one direction) Fig. 16.
18. Position one head bolt into a middle bolt hole. Tighten the bolt 2 turns.

Fig. 17 Tap Dowel Into Block:

19. Use a long thin drift punch as a tool and insert it into the front and rear cylinder head bolt holes on the exhaust manifold side of the head Fig. 17. Tap the dowels down below the head gasket.

NOTE: Do not lift/pry the cylinder head straight up. This can cause the cylinder to pull up and out of the block.

Fig. 18 Cylinder Head Removal:

20. Place a piece of wood against the cylinder head and strike it with a hammer. Repeat on all sides of the cylinder head until the head is loose Fig. 18.
21. Remove the cylinder head bolt.
22. Remove the cylinder head.
23. Remove the cylinder head gasket.

Fig. 19 Dowel Extractor Special Tool 7314:

24. Use Special Tool 7314 to remove the cylinder head locating dowels Fig. 19.
25. Stuff the cylinder bores with clean lint free shop towels.
26. Install cylinder liner clamps (Tool 7315) to hold the liners in place.
27. use a gasket removal compound to s6ften the old gasket material.

CAUTION: When cleaning the cylinder head and block mating surfaces, do not use a metal scraper because the surfaces could be cut or ground. Instead, use a wooden or plastic scraper.

Fig. 20 Oil Feed And Return Holes:

28. Make sure that gasket and/or foreign material does not enter the oil feed hole or the oil return hole Fig. 20.
29. Rinse and wipe clean the cylinder block and cylinder head mating surfaces.
30. Check the liner protrusion. The liner protrusion should be between 0.05 mm and 0.12 mm (.002 in and .005 in).
