Question for you guys; my knock sensor wiring was damaged (possibly by a rodent) and need to repair it. I've heard from some that using solder joints around the engine could lead to leaking solder or breakdown due to heat vs. using a crimp butt connector. However, I'm planning to use a 96% tin 4% silver solder which has a melting point of ~440 degrees F, which seems high enough to not worry here. What kind of outside manifold temps would you estimate?
