Very odd noise????

[91 twin limited]

Hi, I own a 91 RHD Supra, there is a very odd noise coming from behind the right driver side rear of the car? It sounds a little bit like a percolating noise, as if someone is brewing coffee, it's really strange, it's not always present, but I'm hearing it more and more, anyone have this before or any ideas what it possibly could be?

Wheel bearing will make some odd noises

Is it only there while moving or does it make that noise while idling?

It's there while I'm idling as well. But I don't hear it all the time, sometimes I hear it when I go for a drive, other times I don't, it's very strange?? It almost sounds like it might be coming from my gas tank?

Make sure your evap/canister vacuum lines are hooked up and routed correctly.

Not sure why this would happen all of a sudden, no work or service has been done to the car? The car is only a weekend cruiser on sunny days. But I will look into the evap/canister vacuum lines.

I said that because you said a percolating noise. Fuel tanks can make noise like that with heating and vaporization when the system is not hooked up correctly. This is only a possibility. I can't see it from here.

Check your rubber stops on the hatchback. If they're worn down, they allow the hatch to rattle just a little depending on the road surface or the natural vibration at idle. It drove me crazy for years before someone here suggested the stops as a possibility.

This thread will show you what new ones look like.

Is the sound different from the very common "waterfall" noise that comes with air in the coolant system (usually paired with a BHG)?

You were right, one of my lines had somehow worked it's way loose, thanks for the suggestion!
