Install the crankshaft sprocket on the crankshaft.
FIG : Fig. 16: Install the lower timing chain guides and the right side idler sprocket to the engine block
Position the upper timing chains on the idler sprockets by aligning the mating marks on the idler sprockets with the gold mating marks on the upper timing chains.
FIG : Fig. 18: Have an assistant hold the upper timing chains in position while installing the lower timing chain cover
Install the oil pump drive spacer, the timing chain cover and the alternator adjusting bar by performing the following procedures:

FIG : Fig. 20: After the lower timing chain cover is installed, be sure to wipe the excess liquid gasket from the cylinder heads ...
FIG : Fig. 21: ... and the engine block/oil pan mating surface
Install the right side VTC assembly and the right camshaft sprocket. Align the mating marks on the right upper timing chain with the mating marks on the right VTC assembly and the right camshaft sprocket
FIG : Fig. 24: When the mating marks on the right (rear) cylinder head exhaust camshaft are matched, note the intake side is not yet in line
There are 2 types of chain tensioners; be careful not to install the left chain tensioner onto the right cylinder head.
See Figures 27 through 40

FIG : Fig. 28: Be careful when removing the camshaft and crankshaft position sensors; they are delicate and are easily damaged
FIG : Fig. 29: The water pump cover should be removed to remove the front timing chain cover
Remove the timing chain cover bolts, in the sequence shown in the illustration.

FIG : Fig. 34: Push in on the chain tensioners and hold them in place by placing a pin in the holes as shown
Fig. Fig. 36: When installing the crankshaft sprocket, be sure it is properly positioned
Align the marks on the camshaft sprockets as shown in the illustration and install them to the camshafts.
FIG : Fig. 39: Align the mating marks on the chains with the sprockets, then install them onto the camshafts
Be careful not to confuse the intake and exhaust camshaft sprockets. The exhaust camshaft sprockets are thicker than the intake camshaft sprockets.
After checking that all of the mating marks on the chains and sprockets are correct, temporarily install the crankshaft damper and SLOWLY rotate the engine by hand at least one full revolution to verify the camshaft/crankshaft timing is correct. If the crankshaft stops suddenly, a piston is hitting a valve. Do NOT force the engine to rotate; bent valves will result. Check the mating marks on the sprockets and the chains, and perform any procedures as necessary to correct misalignment.
The engine may produce a rattling noise when it is started. Run the engine at around 3,000RPM in neutral to purge the air from the hydraulic chain tensioner.
