[QUOTE="serickson1, post: 14007774, member: 91111"] Found out the hard way this should be part of our yearly maintenance if you are running high boost levels and aftermarket lowers. This is not a negative thread against ATI.....they make excellent race proven lowers and I have already ordered another 10% lower for my new motor build along with an ARP harmonic balancer bolt. Never thought to check the new factory torque to yield bolt I installed with the new balancer......it appears the bolt backed out a little and caused the failure. Unfortunately the damage to the crank was on the backside of the seal sending metal shavings into the motor and ruining the crank snout..... This is not a thread to bash ATI or start a ATI vs IW debate so do not go there and I will not be responding to any questions or comments that try and go that way.....my bolt backed out....I didn't check it....results below.... Build in progress.....built motor with 4.2KB, E-85, JDM cams, and Lund tune.
