It's a good idea to check the valve clearances before disassembly, so any required new lifters can be ordered from a dealership.

Install the camshaft alignment tool #303-1565, then the phasers and sprockets to the camshafts, tightening the retaining bolts loosely.

28. Turn the crankshaft clockwise and position the crankshaft keyway at the 3 o'clock position. 29. Lubricate the rocker arms and hydraulic lash adjusters with engine assembly lubricant or fresh engine oil. Install the adjusters into their original bores, then install the rocker arms in their correct locations. 30. Similarly, lubricate the camshafts and install them in their correct locations. 31. Install the camshaft bearing caps in their correct locations. Install the cap bolts and tighten by hand until snug, then install the camshaft thrust caps and bolts. Tighten the bolts in four to five steps, in sequence, to the torque Specifications. 32. Install the rear timing chain. 33. Install the timing chain cover. 34. The remainder of installation is the reverse of removal. 35. Fill the crankcase with the recommended oil, fill the power steering reservoir with the correct fluid, and refill the cooling system. 36. Reconnect the battery, then start the engine and check for leaks.

Remove the high-pressure fuel pump drive.

Check each for signs of obvious wear (scoring, pitting, etc.) and for roundness and replace if necessary.

Tighten the bolts slowly and by one turn at a time, until each cap touches the cylinder head, then to the specified torque settings.

Check the valve clearances.
