2G Strange noise

[Brettmclayto]

I’m going to make this a short and sweet as possible. I have this noise in the front passenger side that I’m having trouble tracking down.

Its a raddle, or even possibly a grinding noise I hear. It only happens under acceleration. If I drive the car easy no noise. Easy up a hill no noise. Soon as I lay on the throttle coming out of 1st or 2nd I can hear it. Soon as I let off the throttle it goes away.

If I let go of the clutch too fast and the car lunges forward that noise happens. This is very hard to explain.

Video would be helpful. Upload to youtube and copy the link here.

Could be knock or detonation, I wouldnt let it make that sound anymore because no matter what it is if its not normal then its damaging something anytime its making it, it could even be a bad motor or trans mount grounding out against the frame.

Hard to hear. Sounds like you’re on a dirty road. When do you hear it on the video?

Start off by checking your motor mounts. Also look for anything loose in the engine bay. It is very hard to hear the noise in your video.

Sorry it was raining a bit. The sound I’m talking about is at 42 seconds.

Also this gst is stock if anyone knows please let me know ASAP. I’m going to drain the tranny this coming weekend and replace it. Any suggestions on what I should put in it? Price is not an issue.

42 seconds in. Just for 1 second then it goes away

This one will be hard to diagnose over the inter webs. It’s load related so it could be in the drivetrain. Could also be noise from the turbo. Check for shaft play.

They say not to run the car with it off the ground but that might be what you’d have to do to find the noise.

What’s your thoughts on a loose exhaust?

What’s your thoughts on a loose exhaust?

Maybe. If you haven’t check for exhaust leaks, you should do it regardless. Idk if you’re running a wideband but you don’t want leaks before the wb and certainly not around the turbo.

This this is completely stock besides the internals. Stock turbo, stock exhaust

Still hard to distinguish but sounds like you have a massive exhaust leak. Should check the exhaust manifold/turbo/O2 housing gaskets before starting to drop the drivetrain components. That's way easier, so.

+1 dsmpt. Check the flex pipe also
