Since this has not been done yet, I am going to run it. I do not have mod status SO ONLY POST A RESPONSE TO THE QUESTIONS BELOW OR POST A LINK TO THE THREAD ON THIS FORUM containing someone with a blown engine and I will update this post. I do not want this to be 50 pages of cluster, just the facts answering these questions You can PM too. This thread will only work if YOU ARE HONEST. LIST ALL MODS.

This thread is only to help us get a better understanding of what/why/how some engines are failing.

2/7/2016 - It is my strong belief, from evidence, the cause of engine failure is from sucking up water/oil from intercooler causing rod to snap OR running an insane tune. A catchcan/hole in stock intercooler or aftermarket intercooler is a must.

2/24/2016 - Some people have been removed from this thread throughout its short history because they want to stay anonymous. Don't understand why but "it is what it is."

Thank you.

Will be searching the forum in depth when I have some more time in a few weeks to update this better. Will send PM's to members for more information as needed.

Post links or PM threads of blown engine threads if you run across them.

The info on mmateri's is incorrect. According to his post The rod broke at the crankshaft side and made a nice 4" by 2" hole through the block

Ya I added that after I made that post. His motor failure was due to a tune from what was stated, don't need to say who.

No sure what you are reading. Have a buddy running 5 * that threw a rod. Due to the inherent issues of these motors the increased boost when adding a tune is not helping. Sent from my iPhone using Tapatalk
Who is that?

Seems like most of these blown motors were running a tune.

I can't speak for the others but myself there's no way my 87 perf/ tow tune would cause a piston to fail and I even spoke with 5*. They tune within Ford specs so they're safe to use.
