Engine noise sounds like diesel at idle

[Smitty19TRD]

That's funny because my 2019 T4R with 7400 miles is waaaaay more quiet than the 2017 F-150 2.7 Ecoboost it replaced. The F-150 sounded like a one man band. Worst sounding engine I've ever owned or driven. At 14,000 miles... turbo actuator rattle, constant thunka-thunka-thunka from God knows where, transfer case noise, idle sputter and exhaust burping/farting sound. Pulling up to drive through windows was embarrassing! All of this on a one year old $52,000 truck!



My T4R is pretty quiet. At idle it's often hard to tell the thing is running from inside with the windows up and the radio off. My 2009 Tundra 5.7 had the only engine I've owned that was smoother and even more quiet.

I'll have to agree. When I say noisier, I'm comparing my other Toyotas. It's mainly with the hood up that I notice it.
I drive a 3.5L EcoBoost Explorer for work and that thing is horrible and everyone we have sounds and performs different. No consistency what so ever. Some noises the dealer has been able to identify but it has a faint grinding noise since new and yet to be identified.

They took off the valve cover and checked out the head.

Reason I ask is because the shop claimed the engine needs to come out entirely in order to take off the valve covers as there was no space in the engine bay. Not a simple job and $$$ of course.

Were you able to take off the valve covers with the engine in place?

It's still at Toyota. And i have warranty so it didn't cost me anything.

I did my first oil change at 2k using Toyota oil. Did my 2nd oil change at 5K using Toyota oil. Did my 3rd at 10K using Mobil 1 and the engine did seem to get louder but thought it was all in my head. Did my 4th at 15K using Valvoline and it seemed to get even louder. At this point, I knew it was not all in my head. For my newt oil change at 20K I will be switching back to Toyota oil. I always used OEM Toyota filters at every oil change. There is definitely something to be said for Toyota oil. It's made by Mobil however it is different than every oil they sell over the counter. It's made to Toyota spec which seems to make a difference. And yes, I do 5K oil changes. Never will my engines ever see 10K between oil changes.

Have you switched back to Toyota 0W20 yet? If so, did you notice a difference?

Mine makes this terrible racket, I have a hard time convincing myself it's "normal". I've never owned an engine this noisy. The 4.0 in my old Jeep was like velvet compared to this rattly thing.

Makes me want to get rid of it and get something LS powered.

BS. Overhead cam engines don't have rocker arms lol.

Plenty of overhead cam engines DO in FACT have rocker arms.

The Toyota 4.0 is just a noisy engine. Just like the Jeep 4.0 has wrist pin knock. It's just the nature of both engines. I did switch back to Toyota oil and it did quiet down some. Every 5th gen I have heard sounds just like mine does. LS is nice but good luck with GM reliability as a whole.

My ‘09 Tundra 5.7 sounded like a diesel when idling in colder weather. The 4.0 on my ‘19 T4R sounds the same. No big deal because I know it’s normal. I’m in Florida and until this morning when it dropped to 45° F I hadn’t heard the diesel sound everyone is talking about.

The funny thing is people calling the 4.0L a noisy engine. Compared to my ‘17 F-150 2.7 Ecoboost that I dumped, the T4R is smooth and quiet.

Hell, guys pay big $$$ for diesel trucks and they love the sound. Can’t believe people say they’re embarrassed because of the diesel idle sound of their T4R.

First world problems!

Yeah OK.

From Toyota 1GR-FE 4.0 V6 Engine specs, problems, reliability, oil, 4Runner, Tundra, Tacoma

"Dual VVT-i 1GR-FE
In 2009, the Toyota started production of the upgraded version 1GR - the dual VVT-i 1GR-FE engine. That version features not only the variable intake and exhaust valve timing system but also the significant changes in mechanical parts. The bottom of the engine received a new crankshaft with five balance weight, pistons with optimized shape produced 10.4:1 compression ratio versus 10.0:1. The engine also got redesigned cylinder heads.
The valvetrain is equipped with hydraulic lash adjusters.
The camshaft housing now is separate and the valves actuated by roller rocker arms with built-in needle bearings
The pressure in the injection system was raised from 284 kPa up to 324 kPa. The position of the injector nozzle moved closer to the intake valves. In the intake, the ACIS system was omitted. There is a simple plastic intake manifold and electronically controlled throttle body (ETCS-i). The nickel spark plugs were replaced by iridium-tipped spark plugs (Denso SK20HR11). The Dual VVT-i 1GR has new headers (exhaust manifolds).

Yeah we knew that.

Clearly the IP didn't. Time for you to troll somewhere else.

 

[2016 4Runner SR5]

Yeah OK.

Edited post? Like I said, troll.

Just adding info- you are wrong and you know it, now anyway.

19 TRD Pro - 2K miles - more rattle/vibration noise?

Hi All-

I'm new to this forum but appreciate all the knowledge I've gained so far from you all! More recently I've noticed the infamous "diesel" engine sounds, but if you listen carefully it sounds a little more high pitched/vibration like?
If you have about 7 seconds I'd appreciate you listening to the link below and giving me your thoughts :caked:

Thanks!

Same

Apparently it is completely normal . I came here for this very question then joined the site . Got mine gently used at 74k so I was worried but mine sounds identical to your videos .
