    Q:
    How do you install the oil control ring components for the 1994 Chevrolet Astro? Posted by Customer
    A:
    Slip the spacer/expander into the groove, ensuring any anti-rotation tang is inserted into the drilled hole. Install the lower side rail without using a piston ring installation tool to avoid damage, and then install the upper side rail similarly. After installing the three oil ring components, check that both side rails can turn smoothly in the groove.

    Q:
    What should be done if the end gap is incorrect for the 1995 GMC Jimmy? Posted by Customer
    A:
    If the gap is incorrect, double-check the rings before proceeding. If the gap is too small, it must be enlarged to prevent the ring ends from contacting each other during engine operation, which can cause serious damage.
