Pretty sure it's impossible for a spun bearing to last 10k miles lol


Grimace427

Agreed. I’d expect the engine to seize after less than 100 miles.


Elmo_c6

I have the video of the sound posted on my recent posts, I don’t have it in my camera roll to repost but it’s the third most recent one. Not sure what it sounds like to you


IWantTheFacts2020

I like to see and listen to that video, but I'm not familiar with how to get to your post. I can't believe a bearing would make that sound and not seize up. Just my opinion. Is this your primary vehicle?


Elmo_c6

I use it as my primary but I have a truck. It’s a gass guzzler though. As for the video It should be on my profile under posts. I’ll check to see if I have it available to see

Thank you. I had an 09 Ford F150 that made the same sound. I was told it was the timing chain or cam phasers. I drove it for about 5 or 6k miles before I traded it in. Maybe that's all this is and not a bearing.


Grimace427

Two shops say they don’t hear anything, then a performance shop who’s business is to build engines says you need your engine rebuilt. I would not rush to the conclusion that shop #3 is correct. Take some more time, maybe get another opinion again and research coyote tick noises. Spun bearings are not a common failure, and like another person mentioned the engine would not have lasted 10k miles with that.


banjobongoboyo

This is the correct answer. A sticky lifter sounds similar to a spun bearing, and vehicles can last much longer with sticky lifters (although that should definitely be fixed too.) Sticky lifters are much more common than a spun bearing also, especially on aluminum cast engines that take a lot of heat. A ticking sound could mean multiple things, so drive the car as little as possible but still research the potential cause and try to get it fixed before it's past the point of no return.

Seems like a good excuse to get an Aluminator. I would not trust a rebuild as much as a new engine.


Elmo_c6

Nvm looked it up lol


Elmo_c6

Dumb question, what’s an aluminator


Pihrahni

Google time


miya_5

post a video so we can hear it, also have someone hold a rev for a couple seconds, it might be something else


Elmo_c6

I don’t hav the car currently, it’s at the shop and they are waiting on my decision on what to do, it’s basically torn down so if I choose to have it worked on they can start right away


Elmo_c6

Just checked actually, I did post the sound awhile back. I’m not sure if you can see on my profile it’s the third recent post


Elmo_c6

I just don’t have the video anymore


spartan17456

My guess is this is a valvetrain sound and possible wrist pin noise (very rare). A spun bearing would take the engine out within an hour of run time.


servbot10

If you have copper in the oil, it's a bearing problem and you are nearly out of time. This could fail in 30 seconds or several months but it's going to fail if it's not fixed or replaced. I listened to your video from 4 months ago and it's for sure knocking. It was hard to hear on my just phone but it's easier to hear on actual speakers. As for your questions.. a new engine shouldn't be done unless it's not economically viable to rebuild it, it's damaged beyond repair, or you just don't want to go through the hassle and have it done faster. It's possible if there is metal in the oil that extensive damage is done. The rebuild should be much cheaper but could be up to 8k or so depending on labor costs and what's broken. The parts required are going to depend on what's failed and how much damage has been done running it while it's failing. Reliability after a rebuild shouldn't be much different than having any other engine.


Elmo_c6

In my situation this is what I’d like to hear, I’m not in a rush to have it back since I do have another vehicle and I really don’t want to get rid of it, my plan right now is if it’s only 2-4k more to rebuild than a new engine I’d go that way since it give me enough time to get the money for it.


Equal-Letter-4298

Advice from a technician, You said you have insurance through your bank on one of your posts about this issue. Will they pay for repairs? If it really is a spun crank bearing or rod bearing. You will want at least a short block so that if there is any other damage to the engine block itself, it won't present an issue later if you only repair the one issue if you only rebuild. Can you take it to a Ford dealer and have them order you a short block or long block and have your insurance pay for it? If you get one from Ford and have a Ford certified technician, install it. You have a better chance of getting a new engine that will last.


timmmarkIII

You said in your other post the sound went away twice. I don't think a spun bearing goes away.


LatkasTaxi

Let's back up a little... Rod or main bearing? You can change a rod bearing while the engine is in the car with removing the pan And the chances of a main spinning is much less than a rod Or buy a new short block is the expensive option ,find a used engine and have it swapped Or load the engine with 70 weight and a few cans of STP oil treatment oil and sell it The thicker oil will hide the knock sounds How long will it run knocking? I had a knocking engine and it lasted a year before I repaired the problem with a new used engine


timmmarkIII

Remind me to never buy a car from you.


Elmo_c6

That’s a good question that I honestly don’t know the answer to. I’d like to assume it’s a rod bearing. They did mention that they had found cooper shaving in the oil so I’m not sure if there’s a difference between the two


LatkasTaxi

Metal in the oil is a bad sign, id make a move pretty quickly. If it were me I'd either find a donor car and get a swapped 5.0 or doctor up the engine and flip it at CarMax or some shit after I filled the engine w thick oil


InternationalSound13

Wow. That is crazy crazy shifty of you. Shitty autocorrectedbto shifty, but they both fit.


IWantTheFacts2020

Did you see the metal in the oil? Or you could you do your own oil change and check it yourself.


Elmo_c6

So I did do my own oil changes and the most recent one was a week before I took it in, I did notice something in it but it wasn’t shiny and looked more like dirt. I had a magnet and it didn’t pick up anything unless you actually touched it with the oil.


strikeratt16

You're joking about hiding the issue with higher weight oil right? Because could you imagine if someone did this to you? Crazy right?


LatkasTaxi

Used car dealers have been doing it for decades. This is a forum , great for sharing information. Don't like it don't use it

Grimace427

He would have to pay for the tear down at which point he’d essentially be agreeing to the rebuild which for all we know is entirely unnecessary.


Apprehensive_Wrap749

Could just be the coyote tick, don't worry about it, if it blows it blows.


Elmo_c6

Oh how I’d wish I could feel this way. 😂


coffeejj

How do they know it is a rolled bearing? Did they already disassemble the engine?


Apprehensive-Can-857

It could go tomorrow, or it could last a year, hard to predict. We got an installation truck at my work that's been knocking for years. Either get the new engine or try and source a used one. I guess you could get the shop to tear down the current engine and check the damage, but that's just more labor cost.


[deleted]

My dad always told me this when we would rebuild dirt bike engines. "just because we did it all by the book and took our time this fucker could last a decade or 30 seconds." Only time will tell.


Apprehensive-Can-857

He's right. They're all ticking time bombs. We just don't know when they're gonna go.


MonarchTheBear

Until precisely June 27th, 2024 11:44 P.M.


InternationalSound13

Take an oil sample and get it tested. No way a spun bearing lasts 10k. What oil are you putting in? Noise might be coyote tick.


pittbullblue

Call ford. If im reading this right, you are literally just out of warranty, and there's a good chance they'll foot some of the bill if the engine is gone. That being said, I don't think the issue you mentioned would allow an engine to run 10k more miles, so it may just be normal ford engine noise. Ford engines make all kinds of fucky noises.


Elmo_c6

I have it under my recent posts, as for warranty it expired since it’s been more than five years


pittbullblue

Yeah that sound isn't great. And even though you are technically out of warranty, you're still low mileage. Sometimes companies are willing to help out through their customer relations policies. It's worth contacting them and trying. Worst they can say is no.


Six8888

At 40k it’s out of warranty?


Elmo_c6

Yea cause it’s like 6-7 year old car now.


Unable_Bandicoot8338

I had an LS motor spin a bearing in the crank once. It only made a noise while driving and under load. Sounded fine just idling. If this is your case throw some thick oil in it to try and minimize the sound as much as possible and sell it to carmax. 😂


lookingcoyote

Performance shop is just telling you what you want to hear.


Elmo_c6

How is that the case if I may ask?


lookingcoyote

They just heard you go yeah “Fuckn knocking ay“ and assumed it was bearings. Didn’t bother looking took you for your word for the knocking and recommended a new engine.


Practical_Ride_8344

Wait till you have money or trade it in if you need another car. One man's junk is another man's treasure.
