Camshaft Assembly Installation

Tools

8 mm Allen head socket or 8 mm hex key
6 mm Allen head socket and 6" extension, or long 6 mm Allen head socket (preferred)
10 mm socket and ratchet
Flat-tip screwdriver
Flywheel lock 9206 (optional)
27 mm thin-head open-end wrench (eccentric roller tensioner cars only)
19 mm socket (eccentric roller tensioner cars only)
12 mm socket (spring tensioner cars only)

Ensure that all old gasket material is removed from the mating surfaces on the cylinder head and the cam housing. If a scraper is used, work carefully to avoid gouging or scratching the surfaces. Minor scratches may be removed with emery cloth or fine-grit sandpaper.
Ensure the rear distributor housing and cam sprocket are installed.
Set the alignment mark on the cam sprocket to the alignment mark on the rear distributor housing (TDC position).
If old lifters are being reused, install each lifter in the same position it occupied before removal.
If new lifters are being installed, soak them in oil for several hours before installation. After soaking, compress them between your fingers and soak again to minimize the time needed for self-adjustment after initial startup.

Note: A coat of grease on the outside of the lifters will help hold them in the cam housing during installation.

Place a new cam housing gasket onto the cylinder head mating surface. When correctly oriented, the letters "OBEN" or "TOP" will face upward. Correct orientation is critical — incorrect orientation can block the oil supply passage to the cam housing.
Confirm the engine is at TDC (ENG-13).
Place the cam housing onto the cylinder head and ensure it engages the alignment pins on the head. The housing will not sit flush initially, as some cam lobes will be positioned to open their respective valves.

Note: As the cam housing bolts are tightened, the cam may move slightly from the TDC alignment mark. This is expected.

Install the cam housing bolts (M8). A small amount of grease in the Allen bolt head or on the socket tip will hold the bolt on the socket during installation inside the housing. Install the coolant return pipe bracket when installing the cam housing bolts. There is no specified tightening sequence; tighten the bolts so that the housing is pulled down evenly onto the alignment pins. Once the housing is fully seated, torque the cam housing bolts to 20 Nm (14 ft-lbs).
Install and tension the camshaft belt using the applicable portions of ENG-06 and ENG-10.
Install the front timing covers.
Using FUEL-02, install the fuel rail and injectors.
Using IGN-01, install the distributor cap and rotor.
If equipped, reconnect the cruise control cable to the cruise control servo.
Connect the battery negative lead.
