    Stuck or broken exhaust manifold bolts are common on GM EcoTec3 V8s. The Oni Tools Exhaust Manifold Broken Bolt Drill Template fixes them fast—without risking cylinder-head damage. Our hardened alignment plate anchors to existing holes with tapered guide bolts, then slip-fit bushings let you move from port to port without re-centering. A depth reference keeps drilling on-spec, and the included tap-size guide supports clean thread repair when extraction isn’t possible. Engineered for GM EcoTec3 5.3L (L83) and 6.2L (L86/L87) applications on Chevrolet Silverado/Suburban/Tahoe, GMC Sierra/Yukon, and Cadillac Escalade. Built for busy shops yet simple enough for weekend techs, this kit restores sealing surfaces, saves labor hours, and protects high-value heads—everything you need for reliable manifold bolt service on modern GM trucks and SUVs.
