Work has begun on Jeromes 16 Yukon XL. We did a small diag and pulled out the motor. Upon teardown, he had a total of 4 bad lifters, 1 separated into 2 pieces once the pushrod was out. We are going to move forward with a bottom end refresh through our in house machine shop. Clean up the heads and a full Dod/afm delete this way this issue is never going to happen again.
