So for a while my car has been making a weird noise and everyone I’ve been asking is stumped. Ive done research to try and figure it out on my own and used a screwdriver as a stethoscope, nothing.
The noise only happens when im driving and in motion with my foot on the gas. When I open up the throttle while in gear it doesn’t get louder but however gets louder with the speed of the car. When i press on the clutch the sound goes away and as soon as i am back into gear, in motion, on the gas. It starts to click again.
The sound does not occur at idle.
ALL POSSIBLE THINGS I HAVE FOUND THROUGH READING…
-Exhaust Leak (which i know i do have)
-Timing needs to be adjusted
-Rod Knock :[
-Spun Bearing :[
Performance hasn’t changed at all since the noise and yes my oil level is fine.
Any Ideas on what it could be? Ill make a video first thing in the morning at Idle and then when driving. Hopefully my gopro picks it up as they come with sucky mics.
If it changes/goes away when depressing the clutch, it would seem to make one thinks the problem lies within that area.
When’s the last time the clutch/pressure plate/throwout bearing etc were replaced?
about 6 years ago. The clutch is feels fine though, theres no slipping. however that does make sense though. i also forgot to mention axles. how much gap or if any at all is supposed to be there for the passenger side?
I don’t know what you mean by gap… But if it was axles, it would make the sound constantly, and worse when turning sharp… It would t be intermittent or based on usage of the clutch.
hmm… but why is it that nothing feels different…

Depending on whats worn, driveshaft outer joints especially, might make noise only when turning a corner, OR all the time when moving, OR only when coasting, OR only when accelerating.
For another example, on my daily, the throw-out bearing made bit of noise when the clutch pedal was pressed after acceleration, and car allowed to coast a bit instead of engaging another gear. On another identical car, just the opposite, a bit of chatter when engaging the next gear, quiet when coasting… in both cases, no noise after it was replaced along w. the clutch… I don’t mean it IS the throwout bearing, just an example of how you can be fooled by comparing to another identical car.
But since the noise only happens when i let off the clutch it leads be to be something clutch/transmission/axle related right?
[QUOTE=SABsurgery;2278841]But since the noise only happens when i let off the clutch it leads be to be something clutch/transmission/axle related right?[/QUOTE]Yes, I think so. Try to determine if the noise is in relationship to the speed of the car/wheel, in other words same at, say 40 mph, regardless of the gear you are in, or if it sounds different depending on which gear the trans is in.
Also, does it originate on one side of the car. Sometimes you can tell if you roll down first one window, then another, etc.
I’ve leaned that with these cars they tend to transfer noise quite badly… I have had noises on the left sound like they were center or even right…
when diagnosing an external noise I’d suggest you have someone outside listening as well.
