There is a weird (rpm dependant) sound that is like a "wha wha wha" I thought it was exhaust leak but I just did all the exhaust gaskets and it's still there. It's not wheel bearing or tires because of rpm dependency...I'm lost

Post a video of the noise.

I'll try it's a low bass kinda noice

Ok, so video isn't getting anything... I really can't source this sound

It's probably a bearing. That could be your AC compressor, alternator, timing belt tensioner pulleys, water pump or power steering pump. If you have an automotive stethoscope, it'll be pretty easy to find.

Maybe, I don't have a stethoscope though. I do have my ac comp disconnected because there is a short from it somewhere. But it may also be the p/s pump because that thing just wines the whole time. I plan to replace all accessories one day.

A cheap and easy way to check for noises is use a hose or a screw driver and place it against different components and then against your ear. If you can't seem to find it on one of the front rotating assembly's it could be timing belt tensioner pulley. The other thing that it could be, which I believe is my problem, is the a/c compressor clutch rubbing due to lack of clearance.

I have tried the screw driver thing...even went and bought a stethoscope..and I'm not hearing anything. The only other way I can think to describe it is an intermittent humming sound. It happens when I'm holding my foot at just a cruising position or lightly accelerating and stops if I remove my foot from the throttle.

Its probely the Dizzy. I know it sounds stupid...but when the bearings go out it makes a Wha wha wha noise. The only thing you can do is get a reman from Oreilly or autozone or go to the junkyard. You cant replace the bearings yourself, the Dizzy has a stamped rotor hub that dosnt unscrew.

windows, lock and steering movement doesn't work what could be the issue

Slickcam

It couldn't be the windows due to rpm dependency and what do you mean by lock and steering movement?

You figure it out yet? I forgot to tell you...if you want to know if its the Distributor.. take the serpentine belt off and start the car for a couple seconds. If the noise is still there, expect the Dizzy to be bad or the timing belt tensioner.

Slickcam

Not yet. I have a box of parts that are going to be installed on the car once I have the time (including a new dizzy)

I have been working on my wifes mazda nonstop swapping a new motor in.

I would have to take the serpentine off and go for a cruise. I only hear the noise when driving. I kinda feel like maybe a cracked exhaust might be the culprit because I get a burnt exhaust like smell when I really get the rpms up.

Thanks for checking up though, I rashly appreciate it.

Oh ok, and np. Curious myself what you find.

Slickcam

No worries. just got her motor in and all so it should be all finished up before the weekend so I'm hoping I can start my stuff then
