2.0 connecting rod question

Not possitive, but to stay on the side of caution, I do believe all lower end bolts are TTY, as well as the head bolts.
Either way, why risk it? just replace them.

Yes, would appear they are TTY (Torque To Yield) bolts. ARP use to sell them. Check out this excellent discussion, from our CEG's very own: http://www.contour.org/ceg-vb/showthread.php?35601-con-rod-cap-boltsBeing new to rebuilding a 2.0 dohc I have a question.

If the torque ends with a degree figure, say 90 degrees or 1/4 turn instead of a number in foot-pounds then they are TTY bolts. TTY bolts use an angle instead of a final torque because at the last you are essentially twisting the bolt in two, the torque quits going up evenly by then. The bolt will be permanently stretched longer after that one use, why you get new ones. They MIGHT stretch additionally one more time, but gambling with that on rods or mains is sheer stupidity.
