A slight TICKING sound ? Someone please read and help with your extensive knowledge.

[kingtonghsp]

I just bought a 2005 Lincoln LS V8 with 55,000. When I bought it, it was nearly flawless, but it seems to have developed a slight "ticking" sound if you will.

The sound is only present at a certain "SMALL" level of RPM reached, and throttle given. When I slow down to a stop, the sound is definently present for a short second.

To investigate my claim, I put my car in park, and slightly accelerated the gas until the noise was at a constant.

I will try and record a video soon, and post it, along with the RPM it is on.

But does anyone have any clear suggestions?

Is the sound audible in the car or when you pop the hood?


I was not used to overhead cam engines when I bought my Grand Marquis years ago, when they popped the hood, i could hear that. You can hear some ticking and that's normal on these cars.

Unless yours is quite loud, then what you describe is normal.

FOUND IT!

This coil or whatever it is, (has a wire pluged to it) seems to click, and stop after about 800-900 rpms.

if i keep the gas on around 800-900 itll click, and then CLACK, then stop.

Only one doing it. And only at those rpms.

WITH THAT SAID. What should I do? Is it a bad coil? Are they easy to fix?

THIS THING!

What is it? It's clicking/rattling around 800-900 rpms and then clacks and stops.


Is it replaceable or repairable?

Are you talking about the camshaft timing oil control solenoid?
If so, then again it sounds like you are describing normal operation.

there are no coils near the circle in that picture

I had ticking when using under the recommened octane level.

If it's not a coil then what is it?

It has a wire that goes to it. And if its normal operation, why didn't it do it before? And why does it only vibrate and tick and shake at 800-900 rpms, and why does it shake and vibrate at all?

It's the camshaft timing oil control solenoid, as I said.

It's function is to vary valve timing based on engine conditions, such as speed, so it is normal for it to do it's thing at certain engine speeds, and not at others.

You should not see any shaking or vibration. You should not be able to hear it when sitting in the car. If you can, then you probably do have a problem. If so, it is more likely to be something wrong with a camshaft than it is to be the control solenoid.

Can I replace this myself? I hope its really not that big of a deal...

 

[kingtonghsp]

Anyone?

This is DEFINENTLY not normal.


Just wandering...

Can I replace this myself?

How much?

there are a lot of moving parts inside an engine, figuring out what is wrong with a car is next to impossible to do over the internet since you can't see and hear what is happening. with out knowing exactly what is wrong, someone can not tell you how much it will cost to repair, with out knowing you personally and knowing your level of mechanical experience, no one can tell you if the job can be done by yourself.

since it doesn't appear to be a common or wide spread problem, you might want to have the car looked at by a professional to at least diagnose the problem, and then from there you can decide if you want to do the repair yourself.

This is going to seem rude, but it is not intended to be...

No, obviously you can't. I posted a link with the replacement instructions and you are still asking. That makes the answer no. Also, just because this is where the noise seems to come from does not make it the part that needs to be replaced. I already pointed out that it is more likely to be a camshaft (the camshaft itself, the bearings, the chain, ...) problem than the oil control solenoid.
