Installation

1. Apply engine oil to journals and lobes of camshafts, then install camshafts on cylinder head. Intake camshaft has a slit on rear end for driving crank angle sensor.

3. Ensure camshafts can be easily turned by hand, then remove bearing caps and camshafts.
4. Install lash adjusters and rocker arms, then the camshafts and bearing caps, ensuring dowel pins on camshaft sprocket ends are located on top.
