When im driving my car makes like a Can/Plate Rattle and it only rattles during movement but when im idle and i press on the gas there nothing.
I did research it could be heart sinks so i took off the bottom heat sink
I dont know if its the belts or whats wrong And one who experience this can please help me it gets annoying and its pretty loud sometimes

 

what car is it an automatic?

 

Yes its auto.

 

i had thesame problem it is most likely your tranny it did it only when movin i changed my ATF from HONDA oem fluid flushed and refilled the tranny and it stopped shifts a hell of a lot smoother never could figure out what it was here's my thread

I have a similar issue...AC tensioner pulley but I have yet to fix it... Im with Wrona on this one...what are we looking at? If it was a civic draging some coke cans with just married tagged on the back window I tell you its your new wife...boom problem solved...lulz sorry had to throw some humor into this.

 

So this is under determine still ?Because i did change my ATF BTW Wrona we got the same car Honda civic lx 98

 

is the noise only under load? like going up a hill?

If its only under load, more then likely you have a little piece of metal loose in the tranny. I had the same problem...would only make a noise under load...took the trans apart and it was a small piece of metal that somehow broke apart.

Your really going to be more detailed if you want an answer....belts squeak, they dont rattle.

 

Nope i can hear it when i just driving on a flat road...It just sounds like metal or cans being thrown inside my engine bay

 

check all your heat shields.

 

been there done that

 

This seems to be the most up-to-date forum regarding the terribly annoying (and worrysome) issue plaguing our 98 LX's.
Mine recently was serviced for the timing belt @ 155K because it had skipped a tooth. All valves were checked and then over these past few weeks that spurted-rattling sound ONLY during acceleration or increased load has come up. I've done it all... replaced all motor mounts (thinking that this was torque-related and some part of the exterior engine may have been hitting metal; removed the deteriorated heat shields, and inspected for loose bolts. NOTHING.

I read in another forum that there is the possible issue of the doughnut gasket on the connection between the pipe and exhaust manifold? Anyone have luck with that?

We all seem to be facing this same issue at the same time. Please tell me that none of you have found the issue to be a spun rod. I would think that if the issue were major that you would hear the "rattle" while car is in park/neutral and not just under-load and in movement.

My car is all-stock, just a daily driver. No mod's, just as-is. Please help if you can. I've sunk nearly a grand into this car in three weeks. I'm about to push the damn thing off a cliff!

Thanks!!!!!!!!!!!!!!!!!!!!
