Installation
Both cylinder heads
1. CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean.
CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.
CAUTION: The new gasket has a film coating which is crucial to the gaskets ability to seal correctly. Do not scratch the gasket.
NOTE: RH head gasket shown; LH head gasket similar.
Install the head gasket over the dowel pins.
2. CAUTION: Cylinder head machining or milling is not authorized by the Ford Motor Company. Cylinder head flatness must be within 0.0254 mm (0.001 inch) across a 38.1 mm (1.5 inch) square area.
CAUTION: The gasket sealing surfaces on the cylinder head and cylinder block must be clean.
CAUTION: The use of sealing aids (aviation cement, copper spray, and glue) is not permitted. The gasket must be installed dry.
CAUTION: Do not allow the dowels to scratch the sealing surface of the cylinder head during cylinder head installation.
NOTE: The new cylinder head bolts must be lightly oiled with a rag, and allowed to drain for a few minutes prior to installation.
NOTE: RH cylinder head shown; LH cylinder head similar.
Install the cylinder head on the dowels and the head gasket. Loosely install new bolts.
3. Tighten the cylinder head bolts in six stages, in the sequence shown.
^ Stage 1: Tighten bolts to 40 Nm (30 ft. lbs.).
^ Stage 2: Tighten bolt an additional 90-degrees (1/4 turn).
^ Stage 3: Loosen the bolts a minimum of one full turn (360 degrees).
^ Stage 4: Tighten bolts to 40 Nm (30 ft. lbs.).
^ Stage 5: Tighten bolts an additional 90-degrees (1/4 turn).
^ Stage 6: Tighten bolts an additional 90-degrees (1/4 turn).
4. Remove the special tools from both ends of the cylinder head.
5. NOTE: Lubricate the hydraulic lash adjusters with clean engine oil.
Install the hydraulic lash adjusters in their original locations.
LH cylinder head
6. NOTE: Lubricate the O-ring seal with clean engine oil.
Install the oil level indicator tube.
^ Install a new O-ring seal on the oil level indicator tube.
7. Install the LH exhaust manifold.
^ Install a new LH exhaust manifold gasket.
^ Install the LH exhaust manifold.
^ Tighten the nuts in the sequence shown.
RH cylinder head
8. Install the RH exhaust manifold.
^ Install a new RH exhaust manifold gasket.
^ Install the RH exhaust manifold.
^ Tighten the nuts in the sequence shown.
Engines with ratcheting timing chain tensioners
9. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.
CAUTION: Do not compress the ratchet assembly. This will damage the ratchet assembly.
NOTE: LH shown; RH similar.
Compress each tensioner plunger, using an edge of a vise.
10. Using a small screwdriver or pick, push back and hold the ratchet mechanism.
11. While holding the ratchet mechanism, push the ratchet arm back into the tensioner housing.
12. Install a paper clip into the hole of each tensioner housing to hold the ratchet assembly and plunger in during installation.
^ Remove the tensioner from the vise.
Engines with non-ratcheting timing chain tensioners
13. CAUTION: If one or both tensioner mounting bolts are loosened or removed, the tensioner-sealing bead must be inspected for seal integrity. Any cracks, tears, cuts or separation from the tensioner body or permanent compression of the seal bead, will require replacement of the tensioner.
Inspect the RH and LH timing chain tensioners.
^ Install new tensioners as necessary.
14. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.
NOTE: LH shown; RH similar.
Compress each tensioner plunger, using an edge of a vise.
15. Install a retaining clip on the tensioner to hold the plunger in during installation.
Both cylinder heads
16. If the copper links are not visible, mark one link on one end and one link on the other end, and use as timing marks.
17. Using the special tool, position the crankshaft.
^ Remove the special tool after crankshaft positioning.
18. Install the crankshaft sprocket, making sure the flange faces forward.
19. Install the timing chain guides.
1. Position the LH timing chain guide.
2. Install and tighten the LH bolts.
3. Position the RH timing chain guide.
4. Install and tighten the RH bolts.
20. Rotate the RH camshaft sprocket until the timing mark is approximately at the 11 o'clock position. Rotate the LH camshaft sprocket until the timing mark is approximately at the 12 o'clock position.
21. Position the LH (inner) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
22. Install the LH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
23. NOTE: The LH timing chain tensioner arm has a bump near the dowel hole for identification.
Position the LH timing chain tensioner arm on the dowel pin and install the LH timing chain tensioner.
24. Remove the retaining clip from the LH timing chain tensioner.
25. Position the RH (outer) timing chain on the crankshaft sprocket, aligning the copper (marked) link with the timing mark on the sprocket.
26. Install the RH timing chain on the camshaft sprocket, aligning the copper (marked) link with the timing marks on the sprocket.
27. Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
