    I wouldn't be surprised if one of the heatshields above the exhaust has come loose.

    Hmm ok well I've put a whole new catback on the car, removed the main heatsheild (I had to do it to get the exhaust on anyway), checked the cat converter while it was off the car, tightened everything and the sound is still there, I'm pretty certain it's coming from the engine bay, or at least close to the firewall. I took the car to a honda specialist and took him for a drive, he reckons these cars make plenty of strange noises and it's only natural so it's nothing to worry about. he sprayed some stuff around the belts to see if it'd make a difference but it didn't. It's still doing my head in! I've searched the engine bay for any loose objects and tightened lots of bolts and still has no effect.

    I STILL can't understand how it can be so audible but only when you're in the car with all the windows closed. Stationary or moving when the windows are open, nothing. even when you stick your head in the engine bay and rev it, nothing. Not even a mechanic could figure it out! WTF! (and btw it's definitely not the windows vibrating cause it's coming from the FRONT.)

    Rep and serious respect to ANYONE who can provide me with a working solution to this because I seriously do NOT want to take my car to somewhere like honda and have them strip my engine apart trying to find it and charge me $100000000 for it.

    Thanks.

    had the same problem mate and it turned out to be the inside of the header where it joins on to the cat. Just wear and tear unfortunately. So i ended up upgrading the header which then started a chain reaction in mods

    Do you have a shortshifter installed?

    Hmmm, well that would be a likely solution Integra11, but I've already disconnected the cat from the header when I put the exhaust on, and I refitted the cat to it with a bit of silicone to help seal it. so I guess it depends on which part of that connection was vibrating on yours?

    And no I don't have a shortshifter currently.

    Ok so I took off the heat shield on the headers and it didn't make a difference, so it's pretty much narrowed down to noisy valves (which I highly doubt) or something to do with the timing belt, tensioner pulley maybe?

    Gimme some feedback, has anyone else heard of timing belt tensioner pulleys making a rattle, or just generally being noisy? 'cause some peoples threads in the accord forum were about this sort of thing and replacing that part apparently fixed it.

    Either way it's seeming like it's something I won't be able to do myself... Which means I gotta cough up more money.

    Thanks for all the help so far everyone.

    Super DA9, on your first post you did say it sounds like it's coming from the engine/gearbox area and then you said it sound like it's from the passenger side??? The engine/gearbox area is on the driver side. SO where's the sound coming from?? Driver side or passenger side????

    Well by that I mean engine bay and surroundings, but I did think the gearbox was on that side, well maybe I'm just trippin. It sounds like It's coming from where the belts are on the passenger side of the engine.

    But man it's confusing for me too because the only way to hear it is to be IN the car with the windows closed. :S

    It possibly could be some rattles in the car itself. All the hondas i've owned seem to have rattled so much it's not funny

    this worked for me but may not work for you; i can't say for certain.

    i also have a b18c vtir motor and i had that noise as well, which apparently is quite common amongst this particular engine.
    i just lived with it and i'm grateful that i no longer have this noise.

    like integra11 was saying, it could be the join at the header flange.
    every part i changed, i would rev it slowly to the rpm range to see if the sound still existed.
    i noticed that when i changed my header, the sound was gone. who knows, could even have been the exhaust manifold gasket
    slapping between the manifold and the head.

    but all in all, that is what solved my problem.

    best of luck in fixing this problem

    thanks mate, yeah headers are next on my list anyway so we'll see how that goes. It really doesn't sound like it's coming from under the car though.

    Ah-ha! After doing some research and talking to a guy that knows about honda's today, I have a strong theory that it's the timing tensioner pulley. I don't suppose anyone knows of a DIY on replacing this part?
