2013 GMC Sierra 1500. Currently at the dealership: SCAN AND FOUND P0304. CHECK AND FOUND IGNITION COIL FIRING. CHECK AND FOUND NO COMPRESSION ON #4. REMOVED VALVE COVER AND FOUND BENT INTAKE PUSH ROD. RECOMMEND ENGINE TEAR DOWN AND INSPECTION FOR LIFTER/CAMSHAFT DAMAGE. $800 Unfortunately, misfire happened on the way to work, so it's probably done 50 miles since it started misfiring. So I'm going to take it home 5 miles and try the lifter release method. Perhaps AFM delete if it comes to that. Would it be better to drive it the 5 miles with: • New pushrod • Bent pushrod • Removed pushrod? Thanks, Bob

Just became a member. I have a #7 Intake collapsed lifter. 2012 5.3 Sierra with Al block. I believe I am looking for the CPR-007 release tool. Is that the one that comes with the VLOM mod kit? If I am understanding correctly based on your videos. By modifying the VLOM it will prevent the AFM from working? I then can send my ECM to LT1 and have the program it to delete this option?

Good morning! I just received the pushrods and can’t wait to try them out. I loved the little gift you included! One of my lifters/lifter guide failed. Unfortunately, it wasn’t stuck. When I put my little camera in the hole I saw where it was turned. Anyway, that means everything must be done. When I removed the pushrods two of them were bent (same cylinder as the failed lifter). I just assumed I might as well replaced the rocker arms with the upgraded trunions to go with your pushrods. Any recommendations? Should I swap the springs too while I’m at it?
