| *b | Upward |
Install the camshaft sub-assembly.
Apply engine oil to the thrust portion of the intake camshaft sub-assembly.
Place the intake camshaft sub-assembly on the cylinder head sub-assembly with the key groove facing upward.
Align the timing marks (1-dot marks) of the camshaft sub-assembly drive and driven main gears and set the exhaust camshaft sub-assembly in place.
Remove any old seal packing (FIPG material) from the No. 1 camshaft bearing cap.
| *a | Seal Packing |
| *b | 8.0 mm (0.315 in.) |

Note
Do not allow seal packing to contact the oil passage of the camshaft bearing cap.
After applying seal packing, install the camshaft bearing caps within 3 minutes and tighten the bolts within 15 minutes.
Do not start the engine for at least 2 hours after installation.
Install the No. 1 camshaft bearing cap, 3 No. 2 camshaft bearing caps and No. 3 camshaft bearing cap to their proper locations from the cylinder head sub-assembly.
Apply a light coat of engine oil to the threads and under the heads of the camshaft bearing cap bolts.
Install and uniformly tighten the 15 camshaft bearing cap bolts in several passes in the sequence shown in the illustration.
Install a new camshaft oil seal.
Apply MP grease to the lip of a new camshaft oil seal.
Using SST and a hammer, tap in the camshaft oil seal until its surface is flush with the surfaces of the camshaft bearing cap and cylinder head sub-assembly.
