Regal V6-3.8L VIN K (1997)
Camshaft: Description and Operation
The camshaft lobes and timing also reflect the 120 degree spacing. Thus, the even firing crankshaft provides an equal interval of 120 degree between
ignition of each of the cylinders throughout the firing order. The firing order is 1-6-5-4-3-2. The aluminum alloy pistons have slipper skirts and are cam
turned. Four drilled holes or casted slots in the oil ring grooves permit drain back of the oil collected by the oil ring. The camshaft is supported in the
crankshaft by sprockets and chain.
