Moggman said:Mine also sounds nothing like Yelo's. It's not near that loud, and it's more of a pronounced tick, like you can hear each revolution of the engine.
thon said:it could just be an exhaust leak. If its a rod bearing it'll sound like metal on metal (take a screw driver and tap it rapidly on the valve cover...thats what it sounds like)
My best bet would be exhaust leak or heat shield rattle.
Open the hood and rev the motor with the throttle cable bracket on the throttle body and see if you can better isolate where the noise is coming from in relation to the motor.
nate0123 said:if the ticking gets faster with RPMs and is primarily audible under acceleration, it's probably an exhaust leak
blackp5 said:Could be rod bearing. My car made the sound when I started it and also when I accelerated into higher RPMs.
Rac3rX said:Just to double check. To make sure the different issues are clearly seperated by symtoms..
The sound you were talking about from when you f-ed a rod bearing, was this sound evident ONLY when the Engine is under load?(Like when in gear) or is it audible when reving out of gear, also would it be audible with the car in gear & the clutch engaged? During what RPM range was the sound audible?
When reving the car with the throttle cable (If audible at this time) where would the sound be comming from?
Rac3rX said:Here is a sound clip with my hood up from last year, I was hearing a sound, but only under engine load that I havnt heard since I installed my headers. I didnt hear anything out of the ordinary when just reving the motor and at idle.
Do you hear anything out of place in this clip of the engine sound from under the hood?? (Keep in mind the shot from the exhaust is with a 4 inch tip I have since replaced with a 3.5" it was busted and had a little flute sound to it) & I had a wrench and my silencer on my pass seat and when I drive for a bit they bang into eachother.

blackp5 said:Your ticking soudn from the first part of the video in the engine bay sounded different from what I had. I had those clicking sounds when my motor was running good. My was louder and it sounded like metal on metal.
Sea Foam? and I would run it as little as possible with that stuff in w/ the oil, it dilutes it.Rac3rX said:Im looking for the engine cleanser your suposed to run the car on for 100 to 250 miles then flush it out with new oil. PLEASE HELP!!!!!!!!!!!!!!! I cant locate it or what its called.
New oil is a good step. When you change it, check for metal shavings in the old oil (cuz it would be weird for there to be metal in the new oil 0.o). That'll give you a pretty clear indication as to if anything terminal is going on. If you haven't done a "thorough" oil change in a while, let a little new oil drain through the engine to clean up any debris that may not have come out w/ the old oil.Rac3rX said:I dropped in some CD2 Oil detergent & I put some Injector cleaner in the gas today as first steps.
To be on the safe side, Im going to run a flusher through the motor and drop in new oil after I run the car with the engine cleanser.
Ive seen a few products that are oil additives that are suposed to strenthen the internals, any info on those? I know its Not like forging, but stuff to add a little strenth to the medal or something like that. (Ill get more details on the Product my next time at the shop)
Good idea. It won't help your engine noise problem, but still a good idea. I know pep boys carries royal purple tranny fluid, and I'm prolly gonna do that in a few months (when I get to see my car again).Rac3rX said:And Im going to drop in some redline mt90 tranny fluid when I can find some at a good price.
hope I helped.Rac3rX said:Any help would be apreciated.

aMaff said:And please please PLEASE stop beliveing everything you read / see. If you were to read credible information, it all says that very VERY few aditives will "clean" your oil. In fact, most of these additives break down / dilute the oil. While you think you're helping your car, your actually hurting it.
aMaff said:I have my serious doubts abt any fluid that caims to strenghten internals.
aMaff said:Stop throwing your money away on stuff like this, stick w/ the stuff that's been proven to work (tv ads do not count as proof. Magazine ads even less). Just my .02

mryellermp5 said:mine makes the tapping noise at idle..then i hit the accelerator and it goes away. i think people said it was something to do with somekind of vaccum line, but i have no noise at higher RPMS
protegeric said:I read through most of the thread and didn`t see much on this. My car taps or ticks at idle then stops when I rev a little. Under load: nothin. As far as I know, there are no metal shavings in my oil pan. I haven`t pulled the pan off, but never seen anything when I drain it. My other Mazda had problems with the hydraulic lifters and I`ve had them replaced in my other Mazda. Think it could be my lifters? I`m guessing the FS-DE lifters are hydraulic.
Rac3rX said:Does it sound like my engine in the sound clip?
protegeric said:that little background tapping that`s hardly noticable in the clip? yeah kinda like that. it`s a distinct tick or tap. consistent and even, not erratic.
Rac3rX said:I wouldnt worrie Our engine is loud especially with a aftermarket intake.
Chalk it up to Reg engine noises.
People who have had eithor issues with rod bearings & or heat sheild rattles & or exhaust leaks have had more troubling sounds comming from under the hood. None of witch are aparent in the clip (Thank GOD!!)
But Keep in mind your listening to a young engine it had only like 26000klm at the time and only has 37000klm now. On top of this the First 10000klm the engine NEVER SAW ABOVE 4500rpm.
