Hi, I did purchase a 07 Tl Type s 2 weeks ago, recently i found the engine have a cliking sound coming from the engine but not from the head, i did bring my car to the dealership. The service guy did hear the noise and he named the problem a small piston snap and he said this is normal for that engine!! Also i found the vtec won't engage and the rpm cut of at 5500rpm in 1st gear with VSA off when the car doesn't have traction, at time only but for me it sounds like oil pump problem... If somebody can help me, i will feel better!! hehe Thanks for your help.
The car have 44000miles

have you checked oil level?

Acadien

Yes, first it was one liter low, I toped up but still the same. I wonder if is not a safety for the cut off in 1st gear when the wheel spinning...

nfnsquared

Service manual says when vehicle is stopped, fuel cut out is 5000 rpm, so I'm guessing that's what happened....

I got the same car which I purchased 2 months ago...I get the same ticking noise for which I have been told by the Acura dealership and few other friends that this is normal for this engine...Haven't had a chance to get beside the same car just to compare the sound noise...To me it should not sound that way all V6 engines should be running very smooth and noise free....As far as cut off goes mine will cut of as well while at stop at 5500rpms....

nfnsquared

Our engines are known to be noisy at times. Depending on who you talk to, the noise is from the valve train and/or the injectors. Probably nothing to worry about....

Acadien

What type of oil did you put on your engine? 5w20 full synthetic? My brother have a 350z, no noise coming from the engine, for a luxury car i was think it should be very smooth. That's the only think i don't like about the car but if the dealer said it's normal and you think is normal too, hopefully it's normal

I have this same problem and this isnt normal cause the noise just started about 5,000 miles ago now im at 70,000miles . it is on my last nerve I could be normal for a car wid 70,000 mils but not 44,000

donny0391

can one of u guys post a video to see if it is the same noise ?

justnspace

iTrader: (1)

how do you know its the same sound?
no one has described the sound other than a clicking sound.

does it taptaptaptaptaptap?

like nfnsquared said, depending on who you talk too, its characterized as a noisy valvetrain and or injectors.

my '06 with 40,000 miles displays this sound when started COLD. after it warms up the sound goes away.
this tells me that its a characteristic of the engine and most Honda engines display the same noise.

if it goes away after the engine is warm, then it isnt something to be worried about.

donny0391

my noise doesnt go away =/ I have a video but the noise is very vague im trying to upload it ..and thanks for the help earlier

^cant see vids at work.

is it a tapping noise?
taptaptaptaptaptap? tatatatatatataata?


I also used a different weight of oil this time around and I believe the tapping sound is more pronounced....or maybe the cold weather is making it louder. time can only tell as i do more testing

donny0391

lol at work and on the internet kool me too. its more of a clicking noise like when u tap a pen on a school desk ? thats best describes it sorry

Comptechtl2367

Could it be the injector pulse? You have no idea how many people call me freaking out that their car is making a tick noise and its just the injectors...

Passing You

I just bought an '06 with 92k miles and it makes a similar "tapping" sound as described. After reading multi

Passing You

After reading multiple threads on here I'm not too worried about it. I also purchased an extended 5 yr 100k warranty so that gives me a little extra peace of mind. Sorry about the double post. Blame my iPhone.

donny0391

I kno its nothing to be worried about but is there a solution for this ?

donny0391

I have no idea what a injector pulse is sorry ?

donny0391

is this the noise, link below

Sounds like my engine when it's cold.

FYI, I also adjusted my valves when I did my TB change. My intake valves were a little loose (by 0.001"). The adjustment made no difference. Sound is still there when cold.

I don't think you have anything to worry about. If you're really freaked out, take it to a dealer. I'm pretty sure they'll tell you the same thing.

P.S. what weight oil are you running now?

justnspace

iTrader: (1)

not sure if this directed towards me or donny.

I switched to M1 0w-30.
I might go for M1 0w-40 here in a little.
or the infamous redline. not sure yet.

donny0391

ok I plan on taking it to a dealership in the summer cause I dont have warranty =/...and when u say what weight im running im not sure what that means but I put 5 qt of Quickerstate 5-20 synthetic oil

PittsburghTL

From the vid... that sounded to me like the injectors... Nothing to worry about at all if that's the case...

Injectors/lifters settle with engine use... become louder and then top off at a certain noise level. Tapping that fast at idle is what makes me think it's the injectors. If it was something more serious, They wouldn't tap that fast at idle... they'd be slower and speed up and get louder as you throttle.

Acadien

There's the same noise than mine, the noise is not coming from the head so i don't think is coming from the valve or injector if you put the car on a lift you can hear the noise coming more from the bottom of the engine. The dealership think is a small piston snap from the bottom of the engine and he said the noise is not much noisy to worry about. He said he drive a 3.2 Tl and he have the same noise since 100 000km and now the noise is worst but he have 320 000km. But he said normally the noise is worst cold. For me, no difference cold or warm... I was see a car whith that noise before and it was engine knoking on the crank, that's why i was nervous about that. Hope not because for the warranty, i need to go to u.s.a and i'm from Canada!

donny0391

What can I do to fix it ?

nfnsquared

^^^I'd get a new mechanic....

nfnsquared

Nothing (nothing cheap, that is)....don't worry about it.

donny0391

So true … good thing music fades it out but some days I just want to have a smooth quite ride

PittsburghTL

I agree with "nfnsquared".

Just about every honda I've ever wrenched on, taps a little.

If it worsens... I'd get it checked out by a good honda tech - Someone that knows a little more than I do.

Questions - Did you buy the car new? Has it always been NA?

nfnsquared

Wait, you can hear that inside with the windows rolled up? I don't see how...I'm not there, but I find it hard to believe the sound heard on the video can be heard inside (with the windows rolled up).

I can barely hear the noise while standing outside with the hood down. With the hood up, it's definitely noticeable.

Inside the car, no way. Don't hear it at all...

If you can honestly hear it inside with all windows rolled up, you may want to have it checked...

donny0391

SH*T I do ..I hear it with the windows all the way up =/ I will I guess I have no choice..

donny0391

Whats NA?

Acadien

I can hear the tick tick when i'm in the car without music at idle or when i rev the engine slowly. I think i will book another appointment with the dealership to have a good diagnostic on the car because i think i can hear more the clicking noise after i gave little bit of hard time to my car... Donny let him know if you have answer from your dealer about that.

PittsburghTL

"Naturally aspirated". No turbo, no supercharger ever on the motor.

Just wondering if there was ever any damage done to it.

PittsburghTL

I've heard faint ticks in just about every DOHC VTEC I've ever owned - Even inside the car with the windows up... it's just faint. I still don't think it's serious but if it bothers you or it begins to affect the performance... Then I'd say to go.

One other thought... TRANSMISSION?

donny0391

I hope to hell its nothing with the transmission but no n no NA

PittsburghTL

Okay well that's an easier one...

Is the car a manual trans? If so, does the ticking stop when you push in the clutch?

What I'm getting at, is that it could be a throw out bearing. They can make noise.

Acadien

No difference with the clutch engage

donny0391

im automatic

handy911

Have similar issue. Other posts say I need to check the exterior belt, pulleys, and tensioner.

But for the engine itself, will it be covered under the 7 year powertrain warranty?
