They press into the oil galley openings and sit flush with the plug lip; if removal is required later, the threaded top section accepts a small puller. Made specifically for original DOD\/AFM valley covers, they will not fit non-DOD or aftermarket valley covers.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these plugs stop AFM\/DOD oil flow?\u003c\/h3\u003e\n\u003cp\u003eThe plugs physically block the oil passage under the valley cover so oil cannot reach the AFM\/DOD lifter circuits.
