I know a few people here are having this same noise.. I have tried:

- Replaced the alternator
- Replaced idler pulley
- Replaced tensioner pulley.

- Removed all tension from the belt, noise is still there.
- Noise is there regardless of AC on or off
- Noise increases with engine RPM

like seriously wtf is causing this? Now i think it's probably coming from the engine itself.

Somebody said there is a recall / tsb on the AC unit but i can't find this anywhere.. is there a TSB?

All i can think of now is taking it to the dealer to have them look at it.

 

What about the ground?

 

What about it? not sure what you mean

 

I think he means road noise?

 

Take the belt off and start it if the noise is gone it is most likely the water pump if it still makes the noise with the belt off it's the oil pump

 

Maybe he means the electrical system ground?

I've heard that in an old Celica. The thing sounded like it had a supercharger: as the revs climbed, there was always a weird whining noise coming through the speakers. Ended up being a bad ground feeding back into the electrical system.

Long shot, but maybe?

 

noise is still there with the belt off, so if you're right its the oil pump. If that's what the noise is then does that mean it's on its way out?

hmm maybe. but it really does sound like it's coming out of the engine.

 

Honda wind bro.

 

Mine was at dealer for 2 weeks.


It is back there again.


However, mine only does with A/C on


-Replaced idler pulley
- Replaced tensioner pulley.
- Brand new belt


Noise still there. They now got the Acura district manager involved.


Thank god for warranty

 

^ yeah so i just did that exact same stuff myself this weekend and the noise is there still. Like Utah says it may be the oil pump. Cause it STILL makes the noise when the belt is off completely.

Luckily you have warranty cause i paid $100ish for all that shit for no reason

 

^^


I will update you if they can solve it THIS time.

My dealer did the fix "per the bulletin" last time and it didn't cure the problem. FYI


Then again I own the TSX from hell

 

Per dealer noise is from expansion valve


Has been ordered, will be here Thursday


Interestingly enough lots of Gen 1 TSX owners had same problem, where dealer replaced all bearings, belts, pulleys, only to find its the expansion valve:

His noise is with no belt no ac pressure so no way could it be the expansion valve

 

<p>No offense, but that name is reserved for UTAH TSX </p>

 

So you think its gotta be the oil pump?
Does that noise mean its going to die soon?
Is there a TSB on it?

 

<p>Time to get a Type R oil pump and rev your K series&nbsp;up to 9 grand!</p><p></p>

 

VVVTAKKKK!

I had to look that up to see if its real lol. only thing that comes up is a 99 integra type R oil pump

 

<p>Lol yeah alotta K series builds/rebuilds will source a RSX-S or DC5R oil pump, assuming it fits.</p>
