Yes, but only if you can ensure that they havent been excessively stretched.


The way to do this is you ACCURATELY measure the length of them before installing them the first time, and check that they return to this length before installing them again.

If they are already in an engine, its pot luck wether they are reusable or not, but if its on a 7Krpm road engine not a 9Krpm race motor then personally i would be inclined to re-use them anyway if you know that you built it properly the first time in terms of not over torqueing them, even if you didnt measure the length.
