According to the experts it's imperative to replace the rod bolts when rebuilding. I've read the reason is because when they are torqued originally they stretch? Are they manufactured specifically to do that? If so, why wouldn't that make them weak? If reused why is that any different from reusing other bolts or parts under high torque? What's the science and logic behind this?

Rod bolt are true "stretch bolts" and are properly torqued by measuring the stretch (not that anyone would do that normally).
To me, the backyard barbaric shade tree mechanic, reuse of the rod bolts for a street engine is OK. A race engine is a different case. Hell, we used hi-strength aftermarket rod bolts on the race cars and reused them many times. Never lost a rod bolt. Had beam and bearing failures, but not the bolts. Others opinions may vary. |
