So for the past couple months, I've been trying to figure out what this noise is that my car is making. I cant really describe aside from the sound of a bearing with a pit in the race that makes a "tap tap" added in with a rattling washer.
I've tried to eliminate variables, but I just cant figure it out for the life of me.
My car is a 95, all stock drivetrain + K&N drop in filter and a Jackson racing header.
- When the sound happens. -
The sound does not occur until the motor is warm, and it seems like it happens on warmer days.
Sometimes it slightly makes the noise if i let the clutch out at around 1300 rpms. Higher rpms it does not.
In third, fourth, and fifth gear, at or above 3.5k RPMs. But not first or second.
If I climb a big hill on the freeway, it will make the noise throughout the whole pull.
- What I've tried. -
My first thought was speedo cable, I threw a new one on and it seemed to fix the problem. Until the weather got hot again.
I've removed my A/C belt and tensioner(car has no P/S) thinking it was the A/C clutch. No dice.
I've looked for any type of loose bolt/washer or the like, but it doesnt sound like its just a loose washer, theres an RPM related "tick" associated with it.
Someone mentioned clutch pilot bearing, or TOB, but I've never had one go bad so I dont know what that feels like.
You can hear the sound in this video as my car drives by. I cannot replicate the sound unless the car is under load, it does not make the sound while revving in neutral.
Is my motor gonna asplode?
