My crate Ls 408 ate rod bearings in 500 miles

[Wattzy3]

Atk 408 ate my rod bearings
I have a 71 nova that has a lq4 built forged 408. 799 heads. 4l80
I bought the short block from Atk engines in Texas at the end of feb. after receiving shipment I was in the middle of moving so long story short I never even opened the crate till the end of July. Assembled the engine with all new parts. Broke in per atk procedure. Dropped the oil at 500 miles and it's full of copper. Pulled the engine and all the rod bearings (http://www.amazon.com/gp/search?ie=UTF8&camp=1789&creative=9325&index=automotive&keywords=rod%2Bbearings&linkCode=ur2) are wasted. But because I'm beyond the 90 days from shipment I'm told I'm **** out of luck...wtf should I just cut my losses and find a local machine shop to build the shortblock right. Or continue to play the games that Atk are playing

I would find a machine shop use what parts u can from 408 ATK, to get u back running, but would still stay on ATK and file a complaint

I feel bad about your luck, but I understand why Atk and other companies take the line they do, or they'd go broke from warranty claims. Hopefully they'll work out a deal for ya on the parts.

i own 2 businesses and our product is about a happy customer, if u ask me ATK is shooting themselves in the foot, i would not buy from them. i just bought a new mercedes and if there was a problem they would fix it. i once bought some headers from heidts and the guy on the phone( customer service) said they would fit but i told him they did not, he said u have force them a little but they still did not fit (in trying to make them fit they got scratched) so i was stuck with some crappy headers. i bad mouth heidts any time i can, i was out $1200 because of their customer service.

Mother Teresa is not running these businesses. To provide that level of service/warranty costs money, not just from the guy buying it, but from the other customers as well.

Did you assemble your Mercedes? Is their warranty 3 years? They darn sure better fix it because they included a warranty in the price that you paid for. Did you run diesel through it? Did you alter the computer? They won't cover everything. A new car is a far different proposition than a high performance engine.

I was alerted of all your threads you are posting on numerous forums. It’s funny how the story changes and you throw the blame solely on ATK.

First off, I never got a phone call from you, not even a voicemail, but I did end up seeing a FB message and an email, when I got back from being out of the office. When I got back I did shoot you an email requesting info so that I can help you out. So rather than wait for a response you blast us on the forums. My tech you talked to did tell you that you were out of warranty, but send us some pictures and we would look at them, we didn’t tell you tough luck.

You never said your oil pressure was at idle, any engine builder who asks what your oil pressure typically doesn’t care about idle (for the most part). We took 40-50PSI as at operating temperature under RPM. You are running a stock replacement pump with a standard pressure spring, a stock pump seeing that much oil pressure at idle doesn’t sound right as we have ran a fair share of stock replacement 6.0L LQ4 engines for UPS and at idle we see roughly 25PSI with 5W20 weight oil. Also, we did not blame it on oil pressure issue as a definitive answer, we said it definitely had trash run thru the bearings and looked like an oiling (pressure, pickup clearance, etc.) or detonation issue.

On our Boost/Nitrous series short blocks we know they are going to be run hard, we account for clearances accordingly. On your build file we did use extra clearance half shells to get clearance which tells us we did end up with proper clearances. After you accused the failure of being due to debris left after machining or tight clearances I requested if you felt this way, torque up the best matching bearing shells and take a video/pictures of the setup and measurements and send them to me. This was 2 days ago and you never got back to me, instead you come back on here and blast us some more saying we are NOT GOING TO HELP. We are obviously trying to work with you, but it seems you don’t want help and rather throw the blame on us. You also state that you have only street driven the car with and I quote from your email: “500 mile time frame with zero abuse”, yet your Facebook page shows otherwise with videos of you lighting up the tires on Sept. 1st, seeing what would obviously be more than 5000RPM, I bet that wasn’t the only time. https://www.facebook.com/sarahann.mutch/videos/1418194341544048/

We are still willing to work with you if it is indeed our fault, but you have to help us help you with the information we requested.
