    FAQ

    How many seals do I need?
    Six (6) per engine—one for each tappet cover bolt.
    Is this for 12-valve or 24-valve?
    This M-3900267 seal fits the 1989–1998 12-valve 5.9L Cummins. Later 24-valve (1998.5–2002) engines use a different grommet.
    Sold individually or as a set?
    Sold individually (each). Add six (6) to your cart for a complete engine set.
    What other parts should I replace at the same time?
    We recommend a new tappet cover gasket and inspecting the tappet cover itself for warp or damage.
