Ok, i got my new motor in and I already have an exhaust leak on the headers. How often should I tighten these bolts?

 

Well, thats a question that I don't know what to say to. I used a set of "self locking" bolts that I got from Hooker. I have never had to tighten them. On my other car, I do it when I change my oil. I haven't had a problem with them going out before then. How long have you had them in?

 

tighten the bolts up when the motor is cool, then take it for a ride then retighten them while the motor is still hot. do this two or three times and you should be fine.
