It is frustrating. It was a lot of effort to install only to remove the motor. I do keep reminding myself that it is a machine full of moving parts and stuff like this happens. I'd rather pull it and get it right than have it like this for the next 20 years.
Your right, it does boil down to how ATK handles the problem. So far so good.

Been there done that in 2007, I had a place build my Big Block and had it dyno'ed and then at 200 miles the pickup tube on the oil pump fell off and I had to pull the motor again to have them find and correct the problem...it was a royal pain as I dropped the hood on to the fender when reinstalling the second time and it is now my problem.

At least you found there was a problem during the warranty period but I know its still aggrivating .

Wish you luck on it. Your right still alot of time to take the motor in and out. I had a motor built for my Ford PU and in about 5000 miles a rod bearing went out. Know your pain.

Motor problems are always so frustrating. Sorry to hear about it.

Motor is out and on a crate in the bed of the tundra. Headed to ATK's facility in the morning.

Here is what I have been working on:
