I have a 14 wrx with just over 2800 miles on her. The car has been tuned to Cobb stage one with the Cobb intake since 2000 miles. I've monitored the car since and have done a datalog with no issues. Aside from the v3 and intake, the car is stock.
Last night I went for food and all was well. I went through the drive thru, pulled out of the lot, and I immediately noticed a clicking noise as I accelerated. I pulled into a parking lot and shut the car off and started her up again. The noise was still there.
The best way to describe the noise is as a ticking/clicking sound. It sounds almost as if you stuck something into a running fan and you get the clicking sound of the blade hitting it. The clicking doesn't start until I hit 1800-1900 rpms. If I continue to rev it to around 2500 the clicking stops. I continue past that and closer to 3000 rpms and it's clicking again. It clicks whether it's in neutral or in gear. It does not make the noise while idling. I've done some research and some people have a loose this or that, some say rod bearing, others have a different issue.
I have tried flashing back to stock and that didn't help any.
Anyone have any insight on this?
