exhaust rattle
Well I've been having alot of problems with my exhaust rattling about right in they middle at exactly 2000 rpm. I checked all the heat shield and put screws in it. I bought the buzz kit that honda sells for the service bullitin honda put out and put all the new springs and gaskets in it. And it quit rattleing for acouple days and I was soooo happy. Now its slowly starting to coming back and slowly starting to get louder and louder again. I need some help. It sounds like the exhaust is rattling off the heat shield somewhere but I checked all the exhaust from front to back and I can't figure it out

If I can't figure things out (or don't want to work under car in cold weather),
I find if I go to independent shops (muffler shop in this case) early Monday mornings all the mechanics are standing around and I can get good amount of work done for cheap. |
I have a lift in my heated garage so I don't mind doing the work. I just can't figure out the problem. I can't replicate the noise in park or neutral. Only while driving. Anyone had this type of problem

What does that "buzz kit" consist of? Problem might be the A-pipe itself.
The "A-pipe" is the pipe that goes under the oil pan; it's the 2-into-1 pipe. I think(?) it's actually a pipe-inside-pipe construction. The inner pipe is attached forward, and if the pipe flexes one way or another it buzzes against the outer pipe. No leaks, holes, or any evidence that's visible from the outside. |
The buzz kit consists of 4 new springs / bolts and 2 new gaskets for on both sides of the mid pipe. which everything pointed to that was the problem that Honda put the service bulliten out for. I have a metal on metal vibration noise at exactly 2000 rpm sounds like its hitting a heat shield but I checked all of that and rechecked. I adjusted the A pipe mount on the back of the block also. I pulled it away from the oil pan and retightened it. And after putting all the new parts in the sound went away for acouple days and now its slowly starting to come back and get louder and louder again.

If you open up the back end of the A-pipe, I don't know if you can see the end of the inner pipes. If so, maybe you can judge whether you need to move that mount some different way. Even so, the inner pipe might bend one way or another as it heats up.
I had this on a 95 Integra, and it was just really frustrating. Eventually I used it as an excuse to buy a header... ;) |
I am having a similar buzz on my 97 accord after getting it back from the shop for a timing belt job. I wonder if they tried supporting the engine from under the pipe when they removed the left side motor mount.

Look for a dent in the A-pipe?

If it has an inner pipe at all (I think it does) then yes it's up there too.
That pipe (on my Integra) was expensive, so for about the same money I got DC headers which included that A-pipe. I know there's better pipes than DC, but just saying what I did back then. |
