In this episode of PowerNation Extra, Engine Power hosts Mike and Pat talk in depth about the most critical fasteners in an engine, the rod bolt. The rod bolts see the most stress during engine operation, which makes them critical to know about.
The rod bolts act like a spring. In high performance builds, usually aftermarket parts are used because they are made with superior materials. The torque value and stretch both depend on the material it's made of. When it comes to measuring torque, don't rely solely on a torque wrench as they can vary. The best way to get an accurate reading is with a rod bolt stretch gauge.
Pat and Mike go over why it's important to have, and know how to properly use, a rod bolt stretch gauge. Also, what happens if your measurements aren't reading right, and how to fix it.
