Reusing rod bolts on a tight schedule.

If the engine has never been apart, then you may be able to get away with reusing the rod bolts...

They should not be tightened more than 5 times, or I would recommend replacing them... After 5 clamp cycles they can get stretched too much and weaken... If you use plastic gauge, then only do it once, not many times... Small cost compared to a thrown rod...
