i have a 95 ls integra with 125k on motor and manual trans.. lately ive been hearing a rattling sound.. almost like a ping pong ball is in my motor when i push on the accelerator in any gear.. i cant figure out where its coming from and it bothers the hell out of me.. any help or ideas of what this could be and/or how to solve the problem? thanks guys..

 

is it the fuel injectors ? they are kinda noisy on integras

 

maybe you have something lose in your engine bay...... or can be a exhuast leak, i have the same sound too coming from my exhaust...

 

check the timing, could be pre ignition

Check the heat plate around your cat.

 

thanks for all the input .. ive been told by a friend it might be injectors and ive been using fuel system and injector cleaner, but its done jack **** so far... ill have to check the timing and dont you think if it was an exhaust leak it would be making the noise whether i was depressed on the gas pedal or not? bump please.. thanks again

 

help this ***** out

 

quick afternoon bump.. ive been told it may be detonation.. i just bought new spark plugs so i am going to install and see if that fixes the problem.. ive read in the integra owner manual it could be a vacuum leak, fuel injection system problems, incorrect fuel grade, damaged distributor components, improper egr valve function, clogged fuel filter, low fuel pressure, bad plugs, incorrect ignition timing, leaking wires, compression too low or unequal... anyone with ANY experienceor knowledge about this please post, it would be greatly appreciated.. thanks again guyys

 

cheack you timing too

 

i had a similar problem on my da it was my rod bearings but eventually it got louder so i could tell but was to late so througly check it dont let it go, dont hot rod it till ur sure.

 

bump

 

thanks for that, ill check it out.. it does keep getting louder, or so it seems..
what do you think the cause of something like that could be though?
keep this thread going, this problems gotta get solved, thanks again.. Bump for keepin this DA alive

 

A better description would help. Whenever I hear the word rattle and "ping" pong ball, I think of detonation. Check your spark plugs, if any of them are fucked up (twisted up and ****) then that's a pretty good sign of detonation. If it is detonation you gotta get it figured out fast because you can mess stuff up VERY quickly.

Does it rattle out of gear? Like if you just sit in your driveway and rev. Does it always happen when you accelerate, or is it just when the car is under heavy load (goin up hill or something).

If it happens when you just sit still and rev, AND you've determined it's not detonation, then have someone sit in the car and hold it at a certain rpm and stick your head around in the engine bay, try to figure out what it is.

There really is a lot of stuff in there so to ask strangers on a message board what it could be is like finding a virgin in Hollywood.

Have you actually checked any of the things that have been suggested? Namely timing, loose exhaust piping, loose heatshields etc? Eliminating some of this stuff would be helpful.

 

mine started quiet than finally it was knockin loud as **** after a couple weeks check ur rod bearings

 

check ignition timing, cam timing, valve adjustment, heatsheilds or for any exhaust leaks.

i hate those rattling noises, annoying.

 

Take a screw driver and put the handle up to your ear, and the tip on various parts of the engine.

On my '96 the distributor was shot and rattling quite a bit. Using the screwdriver helped locate the noise precisely.

i have checked the plugs and am replacing them too, i had a problem with the first cylinder not firing because the gap was too big on the plug.. ive located a small exhaust leak where the manifold and downpipe meet, i think the gasket needs to be replaced or the bolts to be tightened.. the sound is does not seem to be as loud in neutral if there is even a sound at all, so basically just in gear while im accelerating and it is worse under heavt load aka uphill etc. i am fixing the exhaust leak tomorrow and replacing the plugs and probably wires too.. ill check the dizzy to see if anything is going on there.. thanks for your help and ill let you all know how it goes. keep posting, thanks again

now that definitely sounds like a timing issue, i think pre-ignition

so you think i should check the timing? i talked to my friend dan (his honda-tech name is: integracingsr) and he doesnt seem to think it could be pre-ignition timing for some reason, but i guess i could check it out and see if that fixes anything.. i just dont understand how timing could cause a sound like this, especially only while im accelerating?.. help!! thanks again for the advice, keep it comin'

 

whould slick 50 engine treatment help if it is coming from inside the motor?

 

Where exactly is it coming from ???????

 

i dont think that slick 50 would work but its another option, thanks for the input

and i cant really locate where the noise is coming from, im almost 100% positive that its motor related its just very hard to pin point it exactly.. i have located an exhaust leak where the mani and dp meet so i am fixing that tomorrow.. keep posting and thanks for everything again guys.. ill let ya know how i make out tomorrow

 

First off, if preignition were the case, your plugs, pistons, rings, ect would probably be melted and your engine would cease to run as it only takes a few cycles for the tremendous heat to do damage. Now you should pull your plugs and inspect them for tiny ***** of aluminum welded to the ceramic insulator - they will look like fly specs. If so, then it is most certianly detonation. You might post a picture of a plug or two.

The damages of detonation are cumulative so the longer you run it like that, the more it will damage the engine.

You may diagnose the problem by assuring that the noise (rattling sound) is only present during higher manifold pressures.

Remedies for detonation are as follows - assuming everything is stock.


Correct plug heat range?
Adequate fuel?
timing correct?
grade of fuel?
Carbon deposits? I've found that Gumout Regane works wonders. Try a couple tanks full.

Just a couple ideas if it really is detonation.

oops yea its detonation, got the confussed....lol, sry bout that, but yea it sounds like detonation. check you timing at the dizzy and timing belt,

 

check your cat.
