    I oil starved the LS1 in my ESP car, and I need to either repair or replace the crank. I'd prefer to turn the journals rather than buy a whole new crank, but I'm not sure whether that's legal. There's nothing in the rulebook, so I'm assuming this defaults to the "whatever the factory service manual says to do," but I wanted to make sure.

     

    Thanks!

    I read this, I don't know the answer - however :
    A) If factory undersize bearings are available then it has to fall under a factory service procedure ?
    B) To protest this would be the weenie protest from hell, and the protestor should be superglued to his steering wheel !
    C) Who will know ? Who will care (see B) ?

    Really hinges on the FSM. Stock class rules state:

    "All repairs must comply with factory-authorized methods and procedures." (under 13.1) If there is no factory procedure to repair this than you will probably be looking for a new crank. No offset grinding, kids. <- was thinking rod journals, sorry long week.
