True, unless its built correctly for the speed.

The only problem we found was the bent rod. Piston tops look perfect, valves are perfect not even the slightest hint of detonation, or anything lean related. We have spoken to our local ford dealer, they have informed us that they have seen a hand full of the new 5.0 mustangs come in with a locked up motor that was a result of a bent rod. Seems to becoming a common thing with these cars. It will come back better then ever!

Assembly line variances, call it what you will (is it a "Friday" engine or a "Monday" engine), still a bit scary to think it can, and does happen. This makes two that I know of for sure now. If it is indeed becoming a known issue, maybe this will finally prompt Ford into giving us a "real" set of con-rods.

Maybe some motors are getting weak rods due to tolerances in the material?

i know you said the pistons are good but can u tell which one he has

I now have each piston revision for the Coyote GT.

The late '12 piston appears to be the same as the 11-12 piston except it has the phosphate coating. The '13 piston has the coating, the extra oil drain back passages, and the gas groove in the second ring land.

From top to bottom: 11-12 piston (03/22/2010-12/08/2011)....Late '12 piston (12/08/2011-02/27/2012)....'13 piston (02/27/2012-current):


11-12 piston:


late 12


13

Maybe it's the fact the cars weren't broken in properly? They say that break in is first 5k or so...

I had the tune loaded, and mine at the track, on Day 2. I think it's more luck of the draw than anything else. Ford puts together a few hundred of these things a day, shit happens. Not nearly as much as it used to, but it still happens. That's why we get warranties.

An engine is an engine. They all have gaskets, rings, bearings, etc. How do you think guys with race cars break their engines in? they have no way of putting 5k miles on it. Some engines wont even last 500 miles before the rods need replacing. I think its more a shitty luck of the draw. IMO

If they knew they didn't have a clue of a clue that would be one thing. It's amazing some of those guys even know how to turn the key on their cars.

So has anyone taken a close look at the new injectors to see if one is stuck?
