Default Strange Noise

Hey guys,

There is strange noise coming from my car. It sounds like 'cluk cluk' and can be heard when idling (very softly) and gets faster and louder as you rev the engine - stationary or moving. I've tried to pinpoint it using a screw driver as a stethoscope but can find exactly where its coming from. I think its coming from under the car but it could be coming from somewhere in the engine bay but masked by other noises. I've listened to the injectors and coil pack and its not the noise that I'm hearing and I'm pretty certain it's none of the pulleys at the front.

I've heard other AU's that have a similar clicking sound as they drive past but I'm not sure if its the same.

Anyone got any ideas on what it could be?

Nah, dunno. But mine's got the same noise - comes on and goes off, so I figure it's the A/C compressor bearing, something else (who knows). Let us know if you figure out what it is (sorry to be of no help).

I had a look again today but this time I used a hose to try and find the noise. There are two different noises that i can hear. With the first, I put the hose up against the engine close to where it connects to the transmission at the bottom (just above the steering rack). I could hear a sound which sounded like oil being beaten and sometimes a high pitched sound like water dripping into another pool of water. This sound can be heard standing next to the car and also through the engine bay. I believe it gets faster as you rev the engine.

The second sound is like the mixer ball when when you shake a spray can. It only seems to happen when you hit the accelerator and will get faster the higher the RPM. When you let go it either goes away or cannot be heard due to other noises. It can be heard louder under the car than in the engine bay because of less noise. I'm not sure if this noise is related to the first one as it gets too loud to tell.

Any help would be appreciated.

Mine is doing the same thing. I originally thought it was an exhaust manifold leak, but when I took it in they couldn't find anything. It gets allot worse the warmer the car gets, and it's much louder underneath than in the engine bay. Cruising along all I have to do is lighlty touch the throttle and the noise gets louder, and of course more frequent as the rev's rise.

I eventually had a set of 4 into 1's put on and the noise disappeared, but after a while came back again. I really hope it's nothing terminal. Ford have heard it, but seem to think it's just engine noise, but they're rather inept and couldn't diagnose a bleeding nose.

put some oil in it. its noisy lifters.

when my car gets low on oil it makes a ticking sound like you described with the spray can ball, which gets faster as the car revs. fill it up with oil and no problems.


that is, assuming you have an I6 lol if you;ve got an 8, ive got no idea lol

there are also additives you can put in with the engine oil that are supposed to help with noisy / sticky lifters....

Hate to go thread mining, sorry.

JMO, did you eventually find the source of the noise?

Haven't found it yet but it is definitely coming from around the around the back of the engine near the sixth cylinder. When i get time I'll check if its not an exhaust leak around the cylinder. I've also got lifter noise which can be heard when i start the car so i'll get that checked out to see if its the cause, but i doubt it as it can't be heard after 3-4 seconds.

If all else fails I'll bring it to a mechanic to see if they can find the problem as I'm thinking its something internal and its starting to drive me crazy.

Just as a note. My car has also got only 160,000 kms on it and has been serviced every 5000 kms.

it seems it may be one of those "factory fitted, no cost options" that would probably be "within tolerance" according to ford...including the likes of rust, driveline backlash and all those other lovely things people have problems with, not to mention the dreaded handbrake...

i'm not too worried, if it lets go, au motors are fairly cheap now...

I've had mine in an engine place and he reckons the engine sounds fine. Funny thing is, You can only hear it from the drivers side when you're cruising along. Or from underneath when you have someone revving it while you stick a length of hose just above the steering rack, while the other end is jammed in your ear...

And yes, you're right. Ford reckons it's just the sound of the engine. But I'm getting pretty sick sick of the tick, tick, tick that only comes along after warm-up or on a really hot day...

I wish the engine would detonate... :evilsasmo
