Man, I just heard the most nightmarish news from the dealer - blown engine - with only 63k miles on it. He says the engine has no or low compression on 1-4 and that they don't really know why, just that it needs a new engine.

I have an f1-50 supercrew fx-4 that has had the oil religiously changed, all maintenance performed and babied. Can't imagine why an engine would just blow.

Heres what happened, I was on the freeway the other day and the engine started sputtering, and then hacking and coughing and I barely limped it off the freeway. Towed to the dealership since I was 120 miles from home.

Upon some basic research, my mechanic is telling me there is a TSB that involves low compression and that it may have to do with faulty plugs or injectors. I did have an injector assembly replaced at 30k under warranty

Anybody got any ideas?

 

Could have had a faulty injector that caused you to burn up a valve or 12, leading to further damage.

I just had 4 injectors done under warrenty at 30k on my 2005 lariat. The bad injector burnt up a valve on cyl 7 and caused me to need a new head.

It may be of interest to you that Ford just extended the warrenty on the injectors on the 2005 5.4L.

 

Wow, that sounds familiar. I had a bad inj replaced at 30k. This sounded like the same problem and I had noticed a slight skip a few days before.

Do you have more info on this warranty extension?

 

You should have recieved a letter of the extended warranty on the FI system directly from Ford.

Your Ford dealership should know all about it.

Contact Ford directly if you have any dealership issues or you want them to fax you a copy of the letter so you can see what avenues you may be able to pursue -
