punched holes in the pan
Not your fault. If the rod was going to let go, your neighbors would have heard it knocking. He wound it up and kept it there like Billy ****** and it bit him.
Id say nothing but, if you feel like it, suggest a rev limiter for his next motor.
The ONLY way you pitch a rod with that kind of force in 60 minutes of owning a new car is acting like a 19yr old.
