I searched already;
make: Honda Accord 2000 SE, AT

If exhaust valves too tight, will that make engine/exhaust to rumble ?

as rpm go higher rumbles get louder.

is it OK to run like this ?
my valve doesn't make any ticking noise, do I still adjust them anyway ?

Thanks in advance.

 

up; hmm, nobody had issues like this ?

 

Am I having A-pipe buzzing noise ?

I don't know if 6th gen cars have A-pipe issue

please give me some info.

Hi JimBlake:

It's not my muffler, sound coming from engine bay near manifold and kind of behind intake TB

and

my valves not ticking at all, so I am thinking - is my valve lash too close ?

Thanks for the reply.

edit:

my cylinder Head being shaved and installed by local shop while they at Head Gasket - after that all these, shsh started.

 

How about a leak in that flex-bellows section of the exhaust pipe. That's sorta in that general area.

Mostly I was just thinking you wouldn't call it a 'rumble' if it was a buzzing noise. Sometimes you just have to hear it firsthand...

 

rumble your talking about is what i got. Its a small exhaust manifold leak near the bottom of the pipe. To me it sounds like a baby harly when i coast at idle and burly press the throttle. Its not loud at all but its there.


only can hear it between 800 and 1.8k rpms

shadow_ridge:

yes, thats exactly what I am having, but mine can hear between 2k rpms and up all the way.

let me see I will pull the exhaust manifold - heat shield off tomorrow.

Thanks for all the help guys.

 

Its hard to diagnose problems like this over the internet, without hearing the noise.

 

thanks again, I found it, bad manifold gasket.
