That's what happens when you let some cowboy drive the truck....

 

H@#$ a little Formagasket and she's good to go podner !!!

 

Soooo your saying I should expect it to happen again soon? Lol

Didn't yours die before you Ever hauled a load with it a while back? Now #### and let the adults talk! Haha

 

No, oh wait...... no I don't think so? Oh I remember but it lasted almost a month. But the failure wasn't my fault and that's my story and I'm sticking to it...lol

 

What kind of boost were you running with the twins?

 

I don't think it has much to do with the tuning or the heavy weights. When mine was being rebuilt it was the 3rd one my mechanic had done in the past 2 months. Mine and one other were MXS's both with cracked flanges under 500k miles and the other was an '07 NXS with over 700k and the whole side of the liner was cracked. Out of those 3 mine was the only one that pulled overweight loads and the NXS had the lower HP 475 Stage 1 tune and the other MXS was stock. I don't think the relief cuts in the heads are doing them any favors.

I considered trying to put lower compression pistons in and seeing if that was the issue but just went back to what was already in it and crossed my fingers. What sucks is it runs VERY well, even seems to pull better than the 2 tuned 6NZ's I have.

 

Oh not to hijack your thread but on mine #5 was the hole with the most obvious damage and these are the rod bearings from that cyl. The rest of the bearings look perfect, they look almost brand new!
