Sooo, let's name this sound.....

[Chino]

Started the other day.

Background:

Stock 4.6 3V Revised spark plug design
Steeda UDP
STS Single Turbo Kit at 7lbs
Stock Headers

Noise is coming from the front of the motor.

Just a shot in the dark but it almost sounds like a bad cam phaser.

 

[G.T]

what fuel injectors are you running?!

edit: on another thought, i think it's too loud to be an injector ticking sound.. i wouldn't let it run for an extended amount of time unless i'm running around with a mechanic's stethoscope trying to find the exact source of the sound.. in case it's a bearing that's gone out somewhere

 

[Steedman07]

i thought it was an injector too, but your right, its too loud. And I agree, I wouldnt run it till its looked at..

 

[JeremyH]

Sounds too lound to be internal maybe something hitting the belt or fan somewhere.
Then again its really hard to tell with out actualy being there.

 

[CraigNnem]

I would take the belt off and run it to see if it still ticks. If it does, then the valve covers need to come off next.

 

[Chino]

Going to look at all the possibilities mentioned as soon as this rain clears up. Hoping that I won't need to see my engine builder any time soon.

Yup for sure

this was a bent rod.....not saying thats what you have....the repition sounds the same but it also sounds like a different noise.


anything occured when you started hearing the sound? how hot was the motor? what gear where you in? what RPM?

 

[Mr. WHO]

Too me it sounds as if your "clicking" is coming from outside the motor. Hard to tell without being there.

As stated above take off your belt and see if there is any difference.

I long screw driver with the handle to your ear and the tip on the engine will help act as a "cheap mans" stethoscope, if you still have the clicking. Double check your exhaust, sounds funny to state that, but sometimes its a leak.

 

[BoostedGT480]

im assuming it gets faster with higher rpm?

 

[ayabrego]

Just take off the belt and figure if its coming from the engine!!!

 

[psfracer]

As mentioned above, take off the belt and restart. That will tell you if its any of the accessories or the belt.

I am going to guess something valvetrain related, phaser or cam follower

 

[Chino]

Car was well warmed up, I was in fifth cruising along and then I hear this noise passing under a bridge. It might've been there earlier but yesterday afternoon was the first I heard it.

 

[chuck@evoperform]

I say name the noise George........

Check to make sure all the bolts are tight in the water pump. I had a similar noise coming from the front of a motor and thats all it was.

Yup, thats what I am thinking too, only because I had a sound similiar to this when I first got my engine built. It was the phaser limiters clicking back and forth. Get on youtube and search for 3v phaser noise. There is a couple of vids on there, maybe that can help you out. But I would just remove the belt before I worried my self too much.

My prediction is a playing card clothes pinned to the frame..it makes that ticking sound when the spokes hit it...

OOPS....wrong generation! LOL

Good luck finding this....subrscribing for future referenc.

Bad tensioner and the chain is slapping?

Bad tensioner and the chain is slapping?

God I hope not. I'll let everyone know soon, going to take it to the local mustang shop and diagnose what's going on. Anybody know how much the phasers are if they need to be replaced?

Um 225 each individual believe
