Installation
1. Clean and inspect the cylinder head for flatness.
2. Position a new cylinder head gasket and install the cylinder head.
3. CAUTION: Always use new bolts.
Note: Lubricate bolts with clean Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G.
Install new bolts. Refer to the location note made during removal and make sure the bolts are installed in the correct location.
1 Install the new long bolts.
2 Install the new short bolts.
4. Tighten the bolts in the sequence shown in three stages.
- Stage 1: Tighten the bolts to 20 Nm (15 ft. lbs.).
- Stage 2: Tighten the bolts to 40 Nm (30 ft. lbs.).
- Stage 3: Tighten the bolts to 50 Nm (37 ft. lbs.).
5. CAUTION: Do not loosen all of the bolts at one time. Each bolt must be loosened and final-tightened prior to working on the next bolt in the sequence.
Note: The short bolts are numbered 2, 4, 6 and 8 and the long bolts numbered 1, 3, 5 and 7. Tighten the bolts in the sequence shown in four stages:
- Stage 1: Tighten the short bolts to 25 Nm (18 ft. lbs.).
- Stage 2: Tighten an additional 180°.
- Stage 3: Tighten the long bolts to 45 Nm (33 ft. lbs.).
- Stage 4: Tighten an additional 180°.
6. CAUTION: Refer to the location note made during removal and make sure the components are installed in the correct location.
Note: Lubricate the pushrods with clean Super Premium SAE 5W-30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G.
Install the pushrods.
7. Install the rocker arms, tighten the bolts in two stages.
- Stage 1: Tighten the bolts to 5 Nm (44 inch lbs.).
- Stage 2: Tighten the bolts to 35 Nm (26 ft. lbs.).
8. If valve train components have been replaced, inspect the valve clearance.
