2018 Engine noise

My 2018 Tacoma Sport 4x4 engine seems to be noisy. Sort of like a ticking that reminds me of noisy lifters in older cars or maybe even a quiet diesel engine. It appears to be worse after engine reaches full operating temperature. I have not had it to dealer yet but was wondering if anyone else has noticed this problem. Also the transmission down shifting seems excessive, sometimes two or more gears just get on the freeway. Thanks in advance for any feedback.

 

The ticking is the direct injection system. Older fuel injectors were port style and injected into the manifold at lower pressures. The noise you hear is the high pressure fuel system spraying fuel directly into the cylinders and is a common sound amongst almost all new gasoline cars.

i found this on youtube. it is not mine but it is what my sr5 v6 sounds like and probably what you are referring to.
it sure sounds like something rattling around in there. i have heard it is injectors before from dealer. is this video really injector noise?

 

The sound though can be annoying is completely normal.

 

hello....my 2019 SR 2.7 l has it also..went two different toyo dealers to ask about noise. same as above all normal in these 3rd gen tacos....

 

Found this article that talks about how the injector cleaning cycle works.

This! It's the direct injectors cleaning themselves.

 

i was told by toyo master technician? it was the vacuum pump...regardless new truck under warranty..engine and tranny 5 yr or 60k.....well see...

 

Sounds like a Tacoma. I actually like the sound.

 

The 2nd Gen tacos made the same ticking as does every other car these days. Every enthusiast forum is full of discussion about the same noise. For some reason, people are just discovering this phenomenon that’s been around for a decade.

Endless discussions since the time of the 2nd gens:

well...for one...my 2015 2.7l never made that noise and if it did. it was alot more quieter than my 2019 model...so you cant blame people for the concern....but alls well

 

You 2.7 was not direct injection, hence no ticking.

 

YOU HAVE A POINT!!!
2015 was a different animal.

 

I think he is saying both his 2015 and 2019 are 2.7, the 2019 2.7 does not have DI does it?

 

To be clear, I’m not trying to be jerky.

Fuel injector “tick” is a complaint that is filling the internet. As almost all cars go to GDI (gasoline direct injection), this ticking thing needs to be understood by more people. You can Google for days, and read about Corvettes and Civics, etc all ticking.

The reason Toyota and other makers put those cheesy plastic covers on their engines with the batting underneath is to reduce the ticking sound. You will also find this on the 4.0l Tacoma engines and in the Runners.

On the V6 Tacos, if you look at the cylinder heads, there is foam right on the engine as well, all in an effort to reduce the sound of the injector “tick”.

If the ticking was from misadjusted valves, this forum would be full of engine failure complaints, which it is not.

 

No it doesn’t. If it’s ticking, it’s likely gonna blow.

 

ok...im no master mechanic..but i was told by toyota dealership...they changed things in the 3rd gen 2.7l engine from the 2nd gen! all i sayed was my 2015 gen 2 if it did make the same noise it was quieter....i just bought a 2019 4 weeks ago after 4 yrs of a 2015....once again noise got me by surprise....

 

It looks like the major changes to the 2.7L happened in the last year of the 2nd gens (2015) when they gave it the dual VVTI. It is still a Port-injected engine (not GDI) as far as I understand.
