Installation

1. Oil the camshaft journals and apply Multi-Purpose Grease D0AZ-19584-AA or equivalent meeting Ford specifications ESB-M1C93-B and ESR-M1C159-A or equivalent to the lobes. Carefully slide the camshaft through the bearings. Lubricate the camshaft thrust plate with recommended quality engine oil and install the camshaft thrust plate with the groove toward the cylinder block (6010).

2. Lubricate the valve tappets and valve tappet bores with SAE 50 engine oil. Install the valve tappets in the bores from which they were removed.

3. Lubricate the ends of the push rods with Multi-Purpose Grease D0AZ-19584-AA or equivalent meeting Ford specification ESB-M1C93-B or ESR-M1C159-A and install the push rods in their original positions. Apply Multi-Purpose Grease D0AZ-19584-AA or equivalent meeting Ford specification ESB-M1C93-B or ESR-M1C159-A to the valve stem tips. Lubricate the rocker arms (6564) and rocker arm seats (6A528) with Multi-Purpose Grease D0AZ-19584-AA or equivalent meeting Ford specification ESB-M1C93-B or ESR-M1C159-A and position the rocker arms over the push rods. Tighten bolts to 24-34 Nm (18-25 lb-ft).

4. Perform a valve clearance check. Refer to Valve Clearance in the Adjustments portion of this section.

5.  CAUTION: To prevent oil from entering the PCV system during air-powered oil fills, the closure hose should be disconnected from the oil fill pipe (6A868) and positioned away from the oil source. Cover the hose port with a shop towel to prevent oil from spilling onto the engine during oil fill. Reconnect the closure hose after the oil has been filled to the proper level.

   Fill the crankcase with the proper grade and quality of engine oil.

6. Install air conditioner. Refer to Section 12-03A for air conditioner service.

7. Start the engine, then check and adjust the ignition timing (refer to the engine decal for correct settings). Connect the distributor and intake manifold vacuum hoses.

8. Install push rods in their original positions.

9. Install upper intake manifold and throttle body as an assembly. Refer to Intake Manifold, Upper in the In-Vehicle Service portion of this section.

10. Install valve covers.

11. Install timing chain/belt and engine front cover. Refer to Engine Front Cover and to Timing Chains and Sprockets in the In-Vehicle Service portion of this section.

12. Connect upper radiator hose and lower radiator hose.

13. Connect transmission oil cooler lines, if so equipped.

14. Install radiator and fill cooling system. Refer to Section 03-03.

15. Operate the engine at fast idle and check all hose connections and gaskets for leaks. Retighten intake manifold bolts and nuts to 31-34 Nm (23-25 lb-ft).
