wierd noise!

Thad · 01-18-2001, 07:05 PM

My stang has been making this shrieky like squeeling noise. Almost like a whistling vacuum leak. it even reacts like one. When i put on the gas it decreases in pitch and loudnees. I've checked my hoses and everything looks fine. It's starting to worry me. Can this be a sign of wearing bearings. If so, of what kind.

Thad, Scott's (Rebel79) cobra sounds like yours in a way... He just posted a video clip in the Blue Oval Lounge section! Look for it, and listen, maybe he can help you...

Hey JL1314, i don't think Scott's whistle is the same as Thad's. You see, Scott's whistle is from his Super charger.

Light Em Up!!!

You might be right, NoSlow5.0!! Maybe you should get a supercharger, Thad... It's a sign...

I notice a whistle in mine also, it seems to get louder with the RPM's. Is it possibly the tranny???

Thad · 01-20-2001, 09:33 AM

My noise tends to decrease with the rpms higher.I don't get it. I'm constantly looking for where it's coming from. It seems to be loudest right at the distributor area. I wonder if the bearings are going bad on it.
Or maybe in the water pump? Everything seems to be working fine so i guees i just have to live with it

I worked on a car with the same problem - it turned out to be a leaking injector seal. When you turn it of, does the noise continue for a second or so?

Hey Thad... that would explain the fuel smell you say you smell!

Thad · 01-21-2001, 09:46 AM

Can you get just the injector seals and replace them? There's a good chance that's it like jl1314 said i've also had a gas smell emmiting from the hood also. I'm not sure if the sound continues after the engine is stopped, or at least i haven't noticed it.
Thanks for all the feedback everyone, by the way.

Hey man it could be the fan clutch. I had that problem too. Does it kinda sound like a supercharger? If so than thats what I think.
