Ticking noise

cbasmas · August 22nd, 2008, 07:40 PM

So heres the deal. I am hoping someone can give me some direction or know what is going on.

Okay I have a 2000 mustang with a 4.6 liter motor that is completly stock. Now when I start the car it runs normally no sounds until I accelarate. The only time I hear the ticking is when the rpms are around 2,500 to 3,000 this happens during decelaration as well. Other than that it hasnt got worst and it has been a couple thousand miles. My performance has not been affected either.

TIA

exhaust leak?

4doorfoxy · August 22nd, 2008, 07:52 PM

A little more info on where the ticking sound seems to be coming from?

BLK2KGT · August 22nd, 2008, 08:05 PM

Could be the DPFE switch. Is your car throwin a code?

cbasmas · August 22nd, 2008, 08:08 PM

I dont think its an exhaust leak and its not throwing any codes. It does sound like is coming from the engine bay though. Thanks for the prompt replies

Whats the DPFE switch

00vabchgt · August 22nd, 2008, 08:14 PM

Differential Pressure Feedback, Exhaust. it has to do with the EGR valve...

BLK2KGT · August 22nd, 2008, 08:14 PM

The DPFEwicth is the Differential Pressure Feedback EGR switch. My car is doin somthin similar. It is throwin the code P0401. That switch goin bad is what is causing it. I have also heard of fuel injectors making a tick sound. Can you tell where in the engine bay it is coming from?

cbasmas · August 22nd, 2008, 08:18 PM

it sounds like its coming from one of the heads but i dont want to say that for sure. Should i have a check engine light if it is coming from the valve

4doorfoxy · August 22nd, 2008, 08:19 PM

Does it happen only when you're driving or can you duplicate the noise in neutral revving?

cbasmas · August 22nd, 2008, 08:21 PM

I can duplicate the noise in neutral. Again i would like to thank everyone for the help

BLK2KGT · August 22nd, 2008, 08:22 PM

I tell you what take a rubber hose (preferablly a radiator type) and place it around where you think you hear the sound and tell us what you hear. Also try different areas around the engin to see if you can tell where its commin from.

BLK2KGT · August 22nd, 2008, 08:23 PM

Could also be your valves, try changin your oil.

cbasmas · August 22nd, 2008, 08:24 PM

I juat changed my oil and it didnt help. I will give the rubber house a shot

02sonicGT · August 22nd, 2008, 10:28 PM

does the rate of ticking increase with rpm in the range indicated? or is it steady within the range? Is it metalic or plastic sounding?

perhaps a valve isn't happy and in that rpm range it just happens to be the right harmonic to let it tick.

BLK2KGT · August 22nd, 2008, 10:32 PM

Did you change it or did someone else change it? How did the hose thing come out?

93HatchsBFF · August 22nd, 2008, 11:03 PM

my car is completely stock as well and when i floor it from 2k it makes a ticking noise for like not even a second so i put 91 octane nomore noise lol but only happens when i floor it so i just keep mu foot out of the throttle

thewayshemoves · August 23rd, 2008, 04:42 AM

mine kinda makes a ticking noise too under acceleration, but it got less when I fixed my big ass exhaust leak.

cbasmas · August 24th, 2008, 07:40 PM

well i brought it somewhere and had them use synthetic oil. I think the noise is coming from the right sid valve cover. This may seem like a stupid question but if infact it is coming from the valve or valves and i decide to get some new heads this should fix the problem?

carnut59 · August 25th, 2008, 11:07 PM

It maybe the timing chain. Ford had problems with the tensioners going bad, causing the chain to wear through the guides faster than normal. I had that problem.

run some fuel cleaner. thats wat mine was
