Here is why my engine locked up

[zemog255]

I completely agree with what you're saying and being able to 100% put them at fault won't happen at this point.

Lets look at the facts:
Car ran and drove just fine on the dyno.
Swapped the injectors
Motor turned over twice then locked.

It wasn't ran hard then shut down, just a simple pull in from the parking lot and drove on to the dyno and turned off. How does that sound like stress due to power or parts being defective? Possible sure but that seems way to coincidental for me. If he pulled into his garage at home and then the next day went out to his car and the motor locked then sure lets blame it on parts or abuse.

Sometimes there are no simple answers in life. Shit happens and sometimes knowbody knows why. I've had more than one fast car and race car so I've seen some weird stuff. I've run faster with two blown head gaskets and three popped pistons then I did the week before when the motor was perfect. Actually raced it for about a month before I figured out something was wrong. So if I can run 5.15's every pass with a screwed motor ( of course this was a race built balanced motor ), I can assume that a ford production motor could pop for no reason. Its part of going fast, you got to pay to play.

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

The OP is allergic to wrenches.

Wow, shops just can't win on the internet.....

I'm not going to go into a long disscution on this because the flames are just going to get fueled.

Car was pulled in, fuel lines removed, injectors/rails were removed, new injectors installed, plugs were pulled, (plugs to be gapped for more nitrous) plugs reinstalled, fuel lines reinstalled. Tried starting car and and motor turned over two times then "clunk" we checked starter then decided to turn motor over by hand to check the flywheel to see if a piece had broke off. Motor would not budge. We pulled plugs again to check for a leaky injector, all cylinders were dry. Pulled valve covers to check timing chains/guides ect. All turned out just fine. Customer said he wants to pull the motor at this point and stroke it, and port heads. So we pulled the motor...... advised customer of what we have found.


Also I have been in contact with the two ford dealership we do business with (bob tomes and five star) bob tomes has had 3 motors with bent rods (two 2012 and one 2013) and five star has had one 2012.

Both of these dealers tell me that there customers had similar stories. Car ran and drove great. Next thing they know the car wont start......

There are other storie on the Internet of 5.0's and boss mustangs have similar issues.

here is a link to another site with 5.0s locking up

I'm sure we can not get all the Internet mechanics to believe us or the other car forums that are having similar issues with the 5.0's locking up but we have worked a special deal with the customer that he is happy with.

Yes I am very happy with the way TS is handling this situation. I know the guys at TS are good guys and I know they won't do me wrong. Can't wait till everything gets rolling.

What blows my mind, is the amount of guys that pull injectors out allowing fuel to spill all over a hot engine. Any time myself or anyone at ts replaces injectors, the lines are disconnected with a rag wrapped around it to soak any fuel that might leak. The rails are then removed with injectors intact via the clips provided by ford. The rails are then taken to a bench where the new injectors are lubed and reinstalled along with the safety clips and the rails are reinstalled with very little to no fuel spilled especially on a hot engine. It takes maybe 2 minutes more to remove the rails vs not removing the rails...

Hey I make sure it's cold. I don't want to set my car on fire like a different shop did to my old mustang.

It's one thing to do it to your own car in your garage, that is your business. But these guys on svt claim to work at a shop. That shows the integrity of them. We pride ourselves on trying to do the best job we can with 0 corners cut just to save 2 minutes.

You didnt know everybody is a mechanical engineer on the Internet. That's the bad thing about it, you get your name dragged through the mud and they don't have a clue. To me as long as the customer is happy with the service he is getting then that is all that matters.

I used to have more fuel in my 86 than a gd diesel motor would use 8-1 AF easily... I never bent a rod or locked up the motor.

If these new rods are that damn pathetic, Ill never own one. Cant afford a 30-40K car and have to spend 10 grand on a motor so it wont blow up, and screw leaving it stock for warranty.
