    Q:
    What should be done if the end gap is too small for the Piston Ring Set in the 2009 Jeep Wrangler? Posted by Aiden T.
    A:
    If the gap is too small, it must be enlarged to prevent the ring ends from contacting each other during operation, which can cause serious engine damage. Carefully file the ring ends from the outside in to increase the end gap. You can Select Your Vehicle to see complete installation and repair tips.
