noise from engine

i've noticed an noice coming from my 09 trd 4.0L. less than 1k miles. it is like a fast clicking noise. i can hear it when the engine idels and when i'm driving slowly through town (by echoeing off of parked cars). it's driving me nuts...is this typical. anyone else notice this?

thanks

 

dont worry its normal for these tacos to make a clicking .if it dont click then u worry.Mine sounds like a little diesel .Thats the trait of these taco motors.Just change your oil regular .and no problems

 

starting to feel better already. thanks

 

ifin it dont click clack .then worry .some are louder then others .mine is kinda loud from others ive heard .but all is good .

 

Yep, my 09 makes the same noise.

 

My 08 4 cyl ticks also at idle. Has anyone on the forum actually figured out what the noise is? I know it's normal, so I'm not concerned, but I am curious.

 

Now I'm not sure with the 4 cyl but with the V6 I would think it is something to do with the VVTI I know a lot of vehicals that employ this type of technology have a Tick that normaly come out of a solinoid. Soliniods Tick its what they do.

 

I have heard all kinds of reasons...I am not sure anyone really knows. There are plenty of theories in other threads. My 09 4.0 has a slight tick to it...not bad as I am used to it now.

 

they all tick, I hate it but there was a thread about a possible fix.

It's from an FJ but I think it may work... I haven't tried yet.

There are many things that tick inside the engine bay. It's all normal unless it's way too loud. After a while of having your truck, you'd know what is normal and what isn't.

 

It's because they are a chain driven motor meaning they don't have a timing belt, but a metal timing chain. It's perfectly normal.

 

You may be right in this case, but my 2007 Honda Civic 1.8 is chain driven and it doesn't tick.

 

I wonder if anyone has tried this here on TW

 

That's funny because I had an 07 SI which has the 2.0 and it was chain driven and it ticked! I didn't know what was louder, the engine or the injectors!

 

When the hood is up I can hear the injectors loud and clear, but the engine is silky smooth and quiet. Until I read the complaints on this forum, I thought the tick noise in my Tacoma was the injectors. Then I realized it only made the noise after it was warmed up at idle.

I've never listened to a Honda K20 motor so I can't compare noise levels with the 1.8, but I do know the 1.8 is a newer design so maybe they designed it to be quieter. The K20 also has 57 more horsepower and revs higher. Then again I just turned 42 so maybe my hearing is going.

 

All of the vehicles I have owned that were chain driven ticked at some point. I had a 2003 Grand Am 2.2L (worthless EcoTech engine) that ticked, a 2003 Nissan Xterra 3.3L (gutless sob) that ticked, my wife's 2004 Corolla 1.8 ticks and my 2006 Tacoma 4.0 ticks.
At some point in the life of a chain driven engine, there is a very good chance it will start ticking.

 

Nissan 3.3 engines have timing belts, but I believe their new V6 engines are chain driven (4.0, 3.5, 3.7, etc..)

 

The VG33 that was found in my Xterra was a chain driven motor.

 

*Correction* My Xterra was a belt, my mistake.
