Timing chain wouldn't get worse and worse and running rough. If the chain let go on an interference motor it would make a big kaboom and then nothing

 

My engine started to run rough and have problems and it turned out to be the battery shorting internally, I replaced the battery and everything was fine, well we can all hope that's your problem.

 

As I was reading your post, my first thoughts were a broken timing chain. The 5.4 3V is an interference engine. If it was at idle at the time it turned loose, you might just get away with one bent rod and valve and fix the chain. Probabilities are high though that the entire engine is toast so be prepared.

A failure of this type at your mileage is not common, if a broken chain is the issue. Have you been doing the maintenance on this engine in regards to changing the oil at about every 5000 miles or sooner? Using the correct oil like a Xw-20 or Xw-30 Ford certified API oil?

 

Any update?

 

Timing chains typically don't break unless the engine is stopped by some other catastrophic failure and even then they're not likely to break.

More likely it's an issue with a tensioner or guide, the tensioners have o-rings that can leak which then cause low oil flow to the head which can wipe out the cam journals.

Tensioner arms have nylon/delrin friction surfaces which can wear out and fail which could cause rough running or allow timing to jump if they get bad enough.

Until it's torn apart it's all guess work.

Any updates?

 

Sorry for the delay. I took it to the dealer and all they said was the motors locked up and a new motor would cost $6,500. I asked him if they checked the fuel injectors and said no and asked why not and said that wouldnt of caused this issue. So just hung up at the point and was going to call Ford later. Then about 1-2 hours later the delaer called me back and said the injectors looked fine. So its been over a week now sitting at the dealer and not sure what Im going to do. being I dont have that kind of money!

 

Yeah, injectors won't cause something like this.

If you can't afford a new engine your only hope might be a used one but then you have no clue what you're getting.

Without knowing exactly what failed there's no way to even begin to guess what fixing your old engine may cost, if a leaky timing tensioner caused oil starvation to the head then you're looking at a new/used head at least and possibly two plus the labor involved.

Bad situation all the way around.

I actually just had a thought, I've been dealing with a guy that runs a shop in Shelbyville for years. Might be worth giving him a call to see what he thinks.

Call Lee at Blankenship Tuning 502-548-6318 , I can't promise anything other than that he's been a stand up guy as long as I've known him and he has a great reputation in the Mustang community.

Hi Steve.

You sure about this?

Several members on here have had their '05 5.4's hydrolock and sieze due to leaking injectors. The OP's symptoms are strikingly similar, so I'd at least keep it on a short list of possibilities. Especially considering that it's the ONLY possibility that offers some recompense for repairs if found to be the root cause. From what the OP stated, I doubt that dealer looked too deeply (my opinion).

Here's one: https://www.f150online.com/forums/3688840-post41.html

IMHO - it's worth pursuing until the injector involvement is either confirmed or unequivocallly ruled out, as the not-insignificant cost of repairs ( short/long block, or reman, and possibly cat replacement ) is in the balance here.

I'd seek another opinion - hell, for $6500 I'd seek several opinions.

Thanks Steve I may just call him for kicks just to feel him out.

MGDfan, I agree and have read the samething here in the forums. The problem is if Ford says its not related to the fuel injectors what can a person do? People here said take to to the dealer and I did now the other other option is to take it to another shop "again" and pay them to check all the injectors. It gets expensive doing this and going in circles. Its no fun either way thats for sure!

 

Good luck & keep us updated!

 

I talked with the Ford Dealer agian today and said for a Ford reman motor he talked with his manger and dropped it down to $5,000-$5,200 out the door thats parts and labor. Thats with 3 yrs or 100K whichever comes first.


Most places want close to $1,000 to break it down and check the engine and see whats all wrong with it.

 

Takes 10. Minutes to pull the fuel rail off and do a leak check on the injectors. I'd get a manager involved immediately, they are usually able to locate an actual Ford warranty rep to talk to.

 

Well I guess that kind of falls into the "you learn something new every day" category.

If it was dumping enough fuel to hydrolock the motor I'd guess the oil pan would be full of fuel as well so the oil should reek of gasoline and possibly the tailpipe as well. The other thing that makes me think it's not a hydrolock is that even after sitting for days it still won't crank over and I seriously doubt the rings are tight enough to hold the cylinders full of fuel for days on end.

The warranty should actually be 3 years unlimted mileage unless something changed recently and I hadn't heard about it.
