Drain Plug Holes

The Time-Sert Fastener Company has developed a kit to repair stripped oil pan drain plug holes. After using the kit, the drain hole is reduced to 12 mm, so you'll also need the new drain plug and washer listed below (available through our Parts Division). You can phone Time-Sert at 800-423-4070 or, in California, at 818-579-1304.
