Well as it would happen to me my 5.0 spun a bearing. I did look at the oil and it is a little low and i believe that plus high revs caused all of this. Now its a new car with barley 1300 miles on it, but it has some mods on it like cai + tune, long tube headers, x pipe, and mufflers. So my question to you guys is, is this covered under the warranty, and if not how much do you think this would cost to fix?

 

According to so many....no warranty coverage.....but.....I would approach the dealer in a very pleasant way and see where they stand. Some will work with you, some will not. If you have a good relationship with your dealer, it will help.

Of course, it also depends on how low the oil was and what caused the spun bearing.

How do you know it spun a bearing?

 

Im pretty sure it is, i wont know for sure till later. But it has that ticking noise and it gets worse as you rev it more, and it got really bad. I was barley able to drive it home it home, i was close to my house so i hope no other further damage was caused. The sad part is that i was going to do an oil change last week but never got the chance to.

Also how many people have you heard about with spun bearings?

 

Blown Header gasket???

 

take the cia and tune off before you go to the dealership?

 

the headers will still be a dead give away.

 

Spun bearings on 5.0....only one other that ran to low on oil. But, I am not all over all the boards so there could be others...or not.

 

Not Supposed to be covered most likely... But if I where you I would talk to daysha before talking to the dealer and see what she thinks. She might have a trick or two up her sleeve

 

If it is a bearing caused by a low oil situation, that is going to be your best case scenario for still having a valid warranty claim. However the symptoms you're describing could also appear with broken or bent ring lands. This would likely be the #8 which seems to have some failure rate with bad tuning.

With the cold air intake and tune, if that was the problem, you're likely looking at purchasing a new engine out of pocket.

 

If you spun a rod bearing it would knock loud as hell, have 0 oil pressure, and most likely throw the rod during the drive home. I wouldn't be so sure it was that...yet.

 

Bad rod bearing will usually still show good oil pressure. Because of the fake oil guage

 

I went a couple of weeks with a spun bearing knocking. But that was back in the day with my 442 that had forged rods and cast iron block. Not this particle metal crap.

Definitely a possibility. Check it out first.

 

Same here... Then the rod went through the block...

 

Wouldn't take that long. I had a knock start on my first 302 right when I got out of my neighborhood. As I went to work it slowly got worse and worse and the knock got louder. Then finally right when I pulled into the parking lot the rod went, I only traveled 3 miles total. I also had oil pressure the entire time.

 

I drove with a rod knock most of the summer untill it sounded like it was going to pop out the side of the block. lol

 

You can have a rod knock without a spun bearing, but not the other way around. If it spins, any time left is borrowed.

 

Hey Rickybender,

I definitely recommend you speak to your Ford dealer as soon as possible. Then PM me and let me know what they say and we can go from there.

I like it when some say take it to the dealer and maybe they will warranty it. FMC is not going to warranty the car with an altered tune, especially after issuing a TSB on modifying the 5.0. The dealer will not repair the car, as they are not going to be reimbursed by FMC for the parts or labor. Removing the tune is not going to hide the fact that it was installed, as supposedly the computer will document the change.

 

This is true, however "if" the failure truly is a spun rod bearing, that does to a degree take the tuning off the table. There has been a number of reports of cars leaving the factory/dealers low on oil. One even on this board that resulted in ford replacing a motor.

Now, my gut here is a failed #8 ring-land caused by a bad tune. But if it's truly a rod bearing, there may be a valid warranty claim.

 

Bad tunes can destroy rod bearings.... Happened to me twice.
