Swapped throttle body gasket now I sound like a turbo diesel

21 tundra
I had a really high pitch frequency sound in my truck so I did some digging and heard about the metal net inside the gasket. So I ordered a new gasket with the part number provided and my intake went from a high pitch noise to literally an intake whistle. I have a stock filter and box.


Has anyone come across this ?
Thank you in advance

 

You sure everything went back together snugly? Might have a little leak. Also, did the new gasket have the rubber ring?

 

I thought that at first but I double checked everything. What do you mean by rubber ring ? It’s a rubber gasket

thank you

 

Can ya post an audio clip?
I don't know about everyone else but I'd like to hear it................
Sorry I can't offer up any help.

 

I have the exact same issue on my 21 except I have the TRD CAI.

 

Yep the rubber gasket. Still sounds like it may have came off the seat. Did you open it when you checked? Mine was flimsy I remember.

 

What’s the part number? Pics of the gasket you installed?

Part Number: 2227150050

 

You’ll need to upload it to YouTube first.

Toyota of Cool Springs has that listed as only working on up to 2019 models... I’m guessing that’s just a technicality but maybe something changed on the intake for 2020/2021? @Roman any thoughts?

Edit: just saw you have a 2019 OP. Not sure what could be wrong.

OP bio says 19' but I believe in his posts he says he has a 21'

 

Ya it’s a 21 sorry. I ordered a new stock gasket let’s see what we can come up with

 

I installed the rubber gasket mentioned above when I installed the TRD intake. No whistle or issues on my 20. But, I'm not running the actual TRD filter, prefer the stock filter over the oiled TRD.

 

I wonder if the stock filter is why you don't have the whistle

 

Could very well be. Not to start a debate or thread jack, but I just don't do the oiled filters, I don't want to mess with re-oiling and from my limited research, a clean paper filter flows just as well and its easier to toss out the old and put in a new when dirty. Just my .02. I also removed the HC filter from the TRD box.

 

I removed the HC filter from the trd box also. I unfortunately don't have the stock air filter anymore to test.

 

Did you try the old gasket again to see if you still have a diesel?

 

I haven't yet, I will be trying that after work today

 

@Airn890 did you ever resolve this? I have the exact same issue and it’s driving me nuts. Replaced the TB gasket with the one without the mesh and my noise got worse.
