hey guys. i am doing my first ls engine rebuild and i know that some of the bolts on it are tty bolts and can only be used once. my question is which one are they? i know of the head bolts and the crank pulley bolt. anymore?

 

If you're doing your first build you should have some torque specs handy. Look them over. Any that say torque to xx ft lbs and then xx degrees are TTY bolts that only get used once. The ones that say torque to xx ft lbs are not TTY.

 

i do have specs handy and thanks for the info
