    Q:
    Why is it important to have the pistons available if the cylinder block requires machine work for the 1992 Oldsmobile Cutlass? Posted by Customer
    A:
    If the cylinder block requires any machine work, including finish honing, the machinist will want the pistons available to check piston-to-bore clearance as the cylinder walls are cut. This measurement is critical and is best left to the machine shop.
