Noise in engine

Hey guys I have a 2017 toyota tundra trd pro and it's making a weird noise and I'm not sure what the problem is. The dealer says there is nothing wrong but that noise doesnt sound normal here is a link to the noise: https://youtu.be/OstKdbQN934

 

Doesn’t sound right to me...

 

I've been twice to the dealer and they keep saying there is nothing wrong and its normal

 

What rpm was that? And which side did you do the recording?

 

That was at cold start and between 2 and 3 and you hear it on both sides but the recording was done on the driver's side

 

Cold start 70° F

Okay that sounds normal but I'm not sure what that noise I'm getting is coming from

 

Tensioner bearing on the serpentine belt?

 

My 16 has a ticking sound sometimes. The 5.7 is a noisy engine.

 

I will tell that to the dealer

 

Start up a new truck at the dealer...my 5.7 does tick as well but does not sound like yours.

 

This ^^^, post #6, is exactly what my 2017, 5.7L, sounds like on both conditions. I bought mine new, have 58,500 miles on it, and run Mobil 1 0W20.

 

Sounds exactly like my 07 with about 155K miles. Neat

OP I can’t say I have ever heard that noise from your vid on my engine. Maybe others who have can chime in but if that noise started to happen all of sudden on my truck, then I’d be concerned

 

Yeah it just started and the dealer cant find a problem with it

 

FYI My engine never really sounded like that.

 

Man that noise is either a pinhole exhaust leak from a header gasket or something rotating. Is there any debris stuck around any pulley? A piece of tape or something?

 

I'm not sure to be honest the dealer has it again I want to see what they tell me this time but that noise is strong and they are saying it's fine which I know for a fact that noise isn't fine

 

It sounds very different than our loud noises that are normal

 

On the video it sounds like some sort of resonance. Like the engine is causing something else to vibrate. Is that video inside a garage or something? See if the sound is replicated with nothing else around.

 

Sounds like the air pump is running faster on your startup. Maybe related to conditions. The air pump does get noiser the colder it gets. If its louder at the passenger side then that's it.

 

The

I went to the dealer and said that there is nothing wrong with the car but that noise isn't normal so I'm going to call toyota care i cant figure out where the noise is coming from

 

I listened a couple days ago, its not a "super bad" type sound, meaning doesn't sound like deep internals of engine. More rotation of something rubbing or wearing out on the externals of engine, I'm hoping anyway. The dealer won't do anything with that sound - has to be a hammer like knock (rod bearing).

Yeah have your own trusty mechanic check it out, they should be able to at least isolate the sound.

Luck. : ^ )))

 

Did you ever find out the issue to this sound? My is making the exact sound.

 

Remove the belt and then start up. That will help you isolate it.

 

Well now I’m invested in a 4 year old thread and there’s no closure.

 

sounds like a bad breakup. free hugs from @hagrid

 

Welcome from OKC!
When you get it figured out please post your findings for the next person in need. TIA!

 

Sounds like a bad bearing to me, but these recordings are hard to diagnose. Removing the belt is a good idea.

 

Ex-squeaze me?

Ass, grass, or gas. Everyone pays for Spraynard's tender affections.
