Ticking Noise

Has anyone else noticed a ticking noise coming from the engine? Turn the radio off, I know it's hard to do, listen while in drive at idle. Mine was an intermittent ticking, but now it's pretty much all of the time. It sounds kind of like how an older car's valves tick.

Is your GT totally quiet? I've heard that it could be the injectors...but that doesn't sound right. I took it to the dealer and nobody know why, but one of the service manager's GT does the same thing.

That kind of ticking I thought you left the turn indicator on ! actually for every GT that I have heard running I can hear that, it bothered me up untill right now that I seen this post so I will ask to see what they say ? I had it on my 05 GT it seem to soften in time.

Fuel Injectors are what I have always been told is making the ticking sound. It is not loud by any means, but pop the hood and you can hear them ticking away.

I've had a lot of EFI cars in my time, but I have never heard fuel injectors making that kind of ticking...for the exception of diesel engines. It really sounds like valves ticking away.

The original 289's had a bad tick, guess Ford did that as a retro thing too
I can't hear the tick over the FRPP's

I have a 66 with a 289 and it's totally quiet...I'm going to buy one of those Engine Ear electronic stethoscopes to pinpoint the noise. Once I receive the tool and pinpoint the culprit, I'll post results.

Any votes for "injectors", "valves", "other"?

Has anybody used an electronic engine stethoscope? I'm trying to decide if it's worth buying an electonic one for $85 or just a regular stethoscope for $10.

I have offen seen a length of PVC pipe used for this. Hold one end up to your ear and place the other end on various parts of the engine to narrow down where the sound is coming from.

I've used a big screwdriver in the past with same results, but I want something flexible and a lot safer than a screw driver or a pipe.

Besides a cold start-up knock (that Ford says is normal) my '05 GT also had a warm engine tick. They replaced the "Phaser" bolt, it has something to do with the VCT. There is a TSB on it, but it was just for early '05 builds. I hope my '07 GT/CS won't have these problems (knock on wood).

Well, my 07 GT/CS has it. It use to come and go, but now it's pretty much all of the time...

I'm no Ford Tech, but it could be the Phaser bolt.

I have no idea, i think it has something to do with changing the timing.

Could be...or something to do with that variable timing deal.

My 07 GT has it on both sides of the engine. My first thought was that it's the OHC and Valves and lifter setup location in the engine compared to a pushrod engine (this is my first modular). The car runs fine and it only has 2000 miles on it so it will probably quiet in time with wear so I've been paying it no mind.

It usually enables one to switch between "stun" and "disintegrate." Useful when you're up against rice-burners.

OK, sorry, that was completely unhelpful; just couldn't resist.
