Noise in engine bay
 

Started to notice this noise recently. I don't recall hearing this before. Anyone knows if this is normal or something to be concerned about?

It's not the clutch

Warning: May be loud!

Are you talking about the high pitched whine? I have that too. It is really clear if you just hit the start button twice and put the car into acc mode. A few other members have reported it too but no one has had any issue with the car with this noise present from what I can tell. I believe the noise comes from the alternator. Atleast that is where it sounds like it is coming from.

If you have access to a stethoscope remove the end to where its just the open hose and you can use that to pinpoint noises.

No, it's the "Tick tick" sound. I thought the high pitch noise was the fuel pump? I have no clue

not the clutch bearing either. pushing the clutch in doesn't remove this specific noise

I couldn't hear any ticktick :/ Using my cellphone speakers at work haha. Fuel pump is behind the passenger seat btw. Better not be hearing it all the way out in front of the car lol.

can't hear it at work but is it just valve chatter? Shouldn't be a concern unless one goes flying through your hood.

you said (while sitting in the car) push the start button to "acc" that's what I meant :rofl2:

Oh well yeah I meant do that and get out of the car to hear it lol. Neither here nor there since we are listening for ticking now ha :roflpuke2:

Ill have to give this another listen once I get home. Cell phone speakers are sucking butts.

Appreciate it :tiphat:

That sounds pretty normal to me. Might be easier if you had 2 cars side by side. Have you changed your oil recently or are you due for an oil change? That has the most bearing on the valve noise/chatter.

Could be a louder than normal tensioner or belt idler bearing.

Yea, changed oil about a month ago. Oil level is between low and high.
Good idea on the side by side check. Maybe in the next meet I'll check with one of you guys :tup:

That's what I think it may be. is that cause for concern?

Its VVEL ticking absolutely normal, with an old oil it does get loud especially on idle, if u have an osirus tune and it didnt have any adjustments its even louder on old oil, so plz change ur oil accordingly.

I dont know if I would worry to to much about it. One way to tell is if you have a automotive stethoscope you would be able to pinpoint the noise much easier. Alternatively if you have one of those infrared temp gauges and you can get it on the pulley you could look to see if any extra heat is coming off the bearing in question.

New oil. Less than 500miles on it. Thanks for the reply

Hmm don't have neither of those.

I added half a litre oil now it's reading high on oil stick but sound is still there. It's nothing I hope

I have the same ticking you speak of. It's normal :)

Ok if its still bothering u soo much (by the way i had my ticking sooo loud that i could hear it outside above engine sound i thought VVEL was done on me, i changed my oil to 5w-30 royal purple and all gone) take it to the dealer they can check VVEL tolerance see if u need new one.

By the way Easter oil from nissan also makes that ticking less, thats what it was mainly designed for noise reduction from vvel.

I could care less if it's just noise just want to make sure it's not dying on me

I have the ticking too. and also on my old mazda. It's normal to me

I thought our engines ticked loudly until I took the cover off a bmw 335. Wow that's loud. And they use a memory foam type padding glued into the cover to reduce the noise.

Yeah i was building my friends i135 and that thing was loud and HOT as hell normal operating temp was ~300F, the wiring kept burning, the wiring maybe cuz of jb4 chip but damn a G2 thickness wire, it was burning baad untill we bought that length and replaced it

Bottom line dont buy a bimmer and over boost it.

Im trying to track almost the same noise, mine might be a tad louder mine is intermittent and only when the car has been warmed up. Does it seem louder near the front of the engine? Thus far when it was making the noise we sound scope a ton of noise from the belt tensioner, I am going to replace it and see, if not a guy at work is afraid it might be the chain tensioner, if it is I might throw in the towel with this car, way too much stress I do not need!

Sounds exactly like what I have. I only hear it when it's warmed up over 200.
I don't think it's anything to worry about. I just decided to forget about mine.

I replaced the belt tensioner today, thus far not a,peep, ill check back after a few hundred miles

I think that's VVEL chatter too.

Any squealing from the belt when the engine is cold? If not, the tensioner is probably okay.

My noise was lower not up by the heads, plus I have a 10 year nissan tech at my store now . And while he never saw one go on a 370 he said they put tensioners on altimas abde frontiers all day long, so that's the route I went.

Hmm. Hopefully that takes care of it then.

Do you have any aftermarket pulleys installed? I haven't heard of anyone needing a new belt tensioner before, but of course any mechanical part can randomly fail.

EDIT: Ah, okay -- might be extra stress on the whole system from the SC pulleys wore it out a bit early.

EDIT Part 2: Wait -- you have a turbo, not a SC? Never mind then.
