Good to Know Always replace conrod bolts during any engine rebuild—never reuse the old ones, even if they look fine. Torque these to manufacturer specifications using a quality torque wrench, and consider using thread locker for extra security. The corresponding nuts are available separately, and there's also a complete conrod overhaul kit if you're doing a full bottom-end rebuild.
