my problem with this is that guys with the forged stuff are grenading too....... are they not tuning right or is there more to this oiling problem ??
honestly? alot is in the tuning, mine blew, I am sure it was either tuning or loss of fuel resulting in detonation.
alot of the ones that have blown were under either turbo pressure, Nos, or jsut after a tune.
Not saying anything about the tuners at all, and I am def not a guru of anything, jsut a good listner
and use alot of common sense.
But if the oiling issue was so bad in all the gen III's wouldnt there be a ton of more engines loosing pistions?
And i may be wrong
but thinking of all the engines that have been lost, I havent seen or heard anyone come up and say the problem or the cause was from Rod/crank area failure, either the rod itself has broken, or the piston has come apart.
The only one I can think of is Bone, he lost the bearings, but also he was running NOS.
Even Chubby , whom never ever changes oil and beats the hell outta his QC and has 70,000 + miles on his QC hasnt had any problems.
These engines are very finicky to tunes, the rings are at the very top of the piston, and have vertually no support, so the least detonation and it could be a disaster, they just can handle the pressure.
the rods, they are just cheesy, good enough to hold around 700hp then your pushing it, they break, then find the easiest way outta the block.

this is just my observations of the engines that have let go, and Kyles is still a mystery, BUT did just leave from getting the truck tuned
