thank you wizzard
my friends also told me it's cast. volvo apply graphite coating to the pistons for better heat transfer.
how about the con rods? also casted?

Depends on the year. I have an '01, and the rods appear to be cast, with machined surface between the rod and the cap. But, in '02, Volvo went to a longer rod, and it is supposed to be sintered metal (metal composite heated to high temperature to bond it together) and it has a "fractured" joint between the rod and cap. Actually made as one piece, the cap is actually fractured at the joint, and the cap only fits the rod one way. But definitely NOT cast, or forged in the sense that we know it.
