Thread: Scraping noise at low speeds.

Also to see if it's the brakes, try riding the brakes with the gas. Just apply the brakes enough for them to touch.

Now I'm thinking it's a problem with your engine again since it's only at certain RPM's. Timing chain or the timing chain dampener if you used one. I don't remember all the things you changed.

Is it the same chain that was used while the pushrods were being bent, it might of stretched? But yeah, I would think it would make noise when reving the engine on jacks.

so you only hear this noise when the car is moving and on the ground?, and you hear nothing when its in the air in drive, and hear nothing when its in park, even if yo u rev it up a bit.

that would be a odd one for sure. maybe trans related, bad gears or something.

i dont know jack about fwd transmissions but when a rwd ring and pinion set goes bad, they tend to make noise when off the gas rolling,(down shifting) like a ringing/hum. and if you would goose the gas( like give it just enough gas to start moving the car while moving and then let off) while in low gear you could feel the slop in the gears.

I haven't done this, but if the axle is not inserted all the way, wonder if it would make this noise when under load. It only making the noise at certain RPM is what is perplexing me. I would point to the Engine or the input side of the transmission for RPMs.
