TIMING(1.8 L DOHC)

2000 Toyota Corolla

Engine Mechanical problem
2000 Toyota Corolla 4 cyl Front Wheel Drive Manual 124000 miles

Hi I had a strong slapping noise coming from the timing chain, so I took off the tensioner and the timing cover. Chain was loose(even b4 taking off tensioner), and I can move the tensioner pretty easily. Sounds like I needs the chain and the tensioner to be safe, but could you tell me how to re-time it, as far as the marks on the cams/crank/chain. Thanx.

# Install the tensioner, using a new O-ring. Torque the bolts to 80 inch lbs. (9 Nm).

# Turn the crankshaft counterclockwise and remove the hook from the pin. Turn the crankshaft clockwise and be sure the slipper is pushed by the plunger.

# Check the valve timing by turning the crankshaft clockwise until the mark of the pulley is aligned with the mark on the timing chain cover. The marks on the camshaft sprockets should be facing each other as shown.

# Install or connect the following:

Silicone sealant to the 2 areas where the timing chain cover meets the cylinder head.

Cylinder head cover. Bolts with washers in the sequence shown: 80 inch lbs. (9 Nm). Bolts without washers: 96 inch lbs. (11 Nm).

Right engine mount. Bolts: Marked A : 47 ft. lbs. (64 Nm). Marked B : 19 ft. lbs. (26 Nm). Nut: 38 ft. lbs. (52 Nm).

Power steering pump

Alternator and drive belt

Right engine undercover
