4.6 liter motor whine noise

[lowcountrylawman]

I have a 02 ford crown victoria(P71) that makes a whineing noise when accelerating. It sounds like a turbo winding up. But without a turbo I don't know how to fix this problem. Its coming out of the air intake manifold. DOES ANYONE KNOW HOW TO FIX THIS????

How sure are you that it's coming out of the intake? We see a lot of front-end accessories make the same type of noise when the bearings fail.

Hey. Pays my bills. :)

I wish mine came w/ a whine

Mine has a whine sometimes too... Then I tell the chick to shut up or shes walking home and it tends to stop! :)

Really though check your intake tubing for holes or mis alignment at the clamping areas.

time for a windsor

Try disconnecting your alternator and going for a test ride. Alternators with one shorted diode out of the normal 6 will make a whining noise.

check the air silencer box that goes between intake tube and tb

When I take the air filter cover off. Its louder and you can feel the vibration in the air intake tubing.

Do you have 03 cobra cams?

Do you have 03 cobra cams?

did you show the motor your certificate of authenticity?



actually, i vote for a vacuum leak around the air intake.

[clubracergt1]

Try pinching off the hose that goes to the idle air control valve, and then the one to the pcv. If the noise stops with either of those, replace the offending part. IACs like to hoot this time of year.

Only one of my fords whine.....

In the past 2 years, I have had 14 different Retired Police Cars in my driveway and none of them made this noise. I have also driven over 50 other Crown Victoria in the last 10 years for work, and I would just do a high speed brake test to shut up the whining thug in the back seat! BUT I am clueless on how to get the sound to stop under the hood. I changed the EGR Valve, thinking it was part of it... no luck

I do appreciate the input and advise everyone is giving me!!!

Sounds like its time to get another CV then.

somebody's OCD about their cruisers ? :shock:

i have only had 2 or 3 ex-police cars, one was a ~186k mile Mustang LX Nebraska unmarked. i got it for $200 :)


anyways, on the last mustang i worked on, the AOD had the line pressures cranked WAY UP (it shifted unbelievably hard) and that tranny whined like the dickens. did the previous owner put a SCT tuner/handheld tuner on it?

there's some smart guys on here, i would let Gerald or Chris, or Robert take a look at it, or Shaun after work. another guy can see stuff you miss.

it's sure to be simple, just hard to pinpoint.

good luck with it.

[lowcountrylawman]

I plan on keeping this one around for awile. She looks good and drives good except for the noise.

Might have to let somebody look at it kinda hard to diagnose a problem like that online.
