Camshafts
CamshaftsThe exhaust and intake camshafts are hollow-cast from chilled cast iron and are driven directly by the crankshaft via one duplex sleeve-type chain each. On the 2.9-liter engines, the intake valve lift is 3.6 mm (small) and 10.0 mm (large). On the 3.4-liter engines, the small valve lift is the same as on the 2.9-liter engines, while the large valve lift is 10.5 mm.
The exhaust valve lift is 9.7 mm on the 2.9-liter engine and 10.35 mm on the 3.4-liter engine.
The timing for both engines is as follows:
