exhaust rattle ?

Bubblerboy64 · 10-25-2006, 05:16 AM

I have a rattle which occurs when the car is slowing down and my foot is off the gas. Seems to be coming from the exhaust and I would guess it is a heat shield. Anyone experience similar or have a better guess. The car is a 2000 (model year) with 23,000. Just got the car! Other then that seems to be in very nice condition.

Check the Catalist converter cover by jabing the exhaust pipe with a hammer not the heat shield itself. The 6 bolts that is holding the heat shield together may be loose or rusted. Replace or tighten these up will solve the problem, if that is the problem.

And welcome to the forum

i bet you its the heatshield

karnito · 10-29-2006, 07:44 PM

It is very typical for Honda and Acura to have this problem. Really!

Bubblerboy64 · 10-30-2006, 12:08 PM

The local tech (not Honda) says the problem is in the transmission. Apparently there are service bulletins related to this. Any one have any similar issues. Gets better as things warm up. Only occurs when the trottle is closed and you are engine braking. I do believe he is correct. I guess I check with the local Honda dealer and see what they have to say. And thoughts ,advice, or sympathy appreciated. John Heckman

I had the same problem on cold starts and left it with the honda dealer for a week and they couldnt figure it out; said it was ok and couldnt hear too much because of the 'sound of the supercharger'. Anyway, I took the car to comptech and they diagnosed it right away and then i went back to honda and they replaced the catalytic convertor and o2 sensor for free.

Bubblerboy64 · 10-30-2006, 02:45 PM

Thinks for the replys. Its either the catalytic converter or there is also a service bulletin related to gear backlash causing a rattle which is very close if not exactly what I am experiencing. Cure is replacing the clutch with and "improved" disc. Not certain I understand how the clutch affects the gear backlash but at least we have some information. I am going to let the local Honda dealership have a crack at the car and see what they think. Keep ya posted and if anyone else has more information let me know. Car goes in Friday. John Heckman

Bubblerboy64 · 11-08-2006, 03:05 PM

The Honda dealer called and reports the car is ready to be picked up. They switched out the clutch disc as per the TSB's and Honda stepped up and covered all but $250.00. If this takes care of my problem I am a happy camper. I am impressed with Honda. A six year old car with 24,000 miles should not require a clutch replacement but I was not counting on them.. I will not forget this when it comes time to buy an other car. John H

pecetrn · 11-08-2006, 05:58 PM

thats great. yeah honda service is truly amazing

Bubblerboy64 · 11-09-2006, 05:26 PM

I picked the car up this evening and replacing the clutch completely resolved the problem. And as stated Honda paid all but $255.34 of the bill so I am very happy. The car runs and shifts great and no more vibrations or rattles. All's well that ends well. John Heckman

my brother just had this problem. they said told him it was a rattle in the heat sheild or the down pipe. then my mechanic and me said it was the thottle bearing(pretty much the tranny) and well now he's getting the tranny droped out cuz the tranny was bad so thats from my personal experience

mcaussie · 11-10-2006, 01:26 AM

I just bought one myself here in Australia, and it's now doing the same thing. Especially between 2-3000 rpm on deceleration. You feel it through the whole car. Do you believe even though i'm about the 4th owner of this vehicle Honda may assist in my efforts? Only has 38500km's on the clock.. 2000 Model as well btw.

Thanks,
Michael

Bubblerboy64 · 11-10-2006, 03:41 PM

TSB is technical service bulletin and here is how you can tell it's not the heat shield. It only and I mean only occurs between 4 and 3 thousand RPM with the foot off the gas (decelerating) soon as you touch the gas it stoppes or if you depress the clutch it stops. Heat shield usually will rattle under more then just this one particular circumstance. The throw out bearing typically makes some noise when you activate the clutch. Typically I believe when the clutch petal is depressed disengaging the clutch. The TSB describes this problem so precisely its obvious that this has occurred to the point that they know the cause and cure for it. The rattle comes from under the dash and is transmitted back thru the transmission tunnel to the back of the car. I believe the sound that is heard is the exhaust knocking against the car but I am not certain. I have no idea what clutch is used to correct but it has stronger springs which dampen the movement in the transmission which prevents the backlash. Once the backlash is held in check this cures the problem. I really can't tell you more then I know. But Honda is very much aware of this issue and if your car experiencing the same symptoms I think I can pretty well tell you the problem is ultimately corrected by swaping out the clutch disc. This is not to say that some people don't have actual transmission problems or that heat shields are not a rattlin as well but if it happens exactly as I have described my problem the solution as unlikely as it sounds is to replace the clutch. Honda says so, and it fixed my car. Hope this helps clarify. John H

Bubblerboy64 · 11-10-2006, 03:47 PM

Chemical, I would suggest that since the transmission is dropped on your brothers car he change out the clutch. Most of the cost in this is getting the transmission out and it would really be a shame to put the trans back in and then discover he had the same problem I had. I certainly would run this past the dealer and he can check his TSB's and he might learn something. Obviously I can't say his problem is the same one I had but it would really be smart to give someone a heads up on this. What do you think? John H

mcaussie · 11-10-2006, 09:02 PM

Went to Honda Australia today here in Queensland, Australia. They believe it is clutch problems. Got it on the hoist. used a crow bar to jiggle things around. No issues. Doesn't help that they have also found a 6 inch crack in the wheel arch that i will have to get repaired.

Don't know what the cost of S2000's are there, but i paid $35000 for mine, $26250 US privately and didn't need this after only 1000km's of driving it.

welll thanx for the adive ill tell him and i think he;'ss getting a clutch anyways so yeah it was going out too

Bubblerboy64 · 11-12-2006, 05:09 AM

I got a pretty good deal on my car. I paid $15000 for it and have spent another $500 to get it completely right. It is a year 2000 with 23k on the clock. I watched the ads for a couple months and knew the prices. It is the end of the season and the guy was getting divorced. It actually was on eBay for a couple hours and when I saw the price I jumped. Cars like mine are being advertised for all kinds of money. Some people just go to Kelley's or similar and think they can get top dollar just because it says so. These cars are down in price right now because many of the dealers have at least one left over '06 car that they are discounting about $4000 off their usually full sticker price. This affects the price of used cars right down the line. A lot of people don't know that. You can buy a new car for under $30k and a '05 with only a couple K on it for $26k. If you look on eBay and go to the "completed sales" listings you will see that first of all very few cars actually reach their reserves. If you study the cars that actually change hands then you can see what the REAL price to pay is. My car realistical could have brought a couple more K possibly but the guy didn't want to detail it and he wanted to move it immediately. I had to take a chance on a 600 mile round trip to check the car out and I did have a good days work to detail it. But other then two tires and this clutch issue its in very nice shape. Won't be driving it much over the next couple months now with the weather in Pa. Good luck to others with the dealers and the repairs. I was lucky to not have to argue with Honda over this. Don't know if they treat everyone the same but I would make some noise and see what comes of it. John H
