Weird tick/rattle

Car is a 1999 gt with 130000kms. When i rev the car it ticks/rattles around 2000 rpm but only when its hovering around that rpm range. If im driving and floor it it wont make the noise. If i decelerate it wont make the noise. Only coasting at 2k and very lightly accelerating past 2k. When its cold like -10 celcius or lower it does it badly. Warmer it gets the less it does it. Both me and my dad have looked and cannot find what it is. Ive used a stethoscope and around the water pump/ timing cover area i can faintly hear it but by ear i can hear it towards the middle/back of the engine. Its a very odd noise. It doesnt happen all the time either. Car still has lots of power with good oil pressure. Running 5/30 mobil 1 changed 2500 kms ago. Please help

Yeah, these modulars are kind of noisy. What you're describing sounds like cam chain noise but who knows? If it's not too obnoxiously loud, I wouldn't lose sleep over it.
If you think that it's abnormally loud, post a video, with clear sound, and we might be able to help.

Could it possibly be an exhaust leak? At the manifold maybe? It only ticks/rattles when the engine doesnt have a load on it. Its not there when you rev it quickly or let it rev down.

You can't rule out anything on a 14 year old car.
Have a look and see if you can spot any dark sooty areas around the manifolds...

My 96 GT had 100,000 miles when I got. It had a noise that like a bb floating around. It sounded like it was coming from the Auto. transmission or back of the block. Turns out it was a bad drivers side timing chain tensioner. I wander if it could also make the same noise if the oil was low? Maybe not pumping it up properly. I replaced my tensioners and the sound is gone. I didn't think the tensioners broke like that. Little noises like that affect OCD bigtime. I hope you find out what it is and it's a simple fix.

I had a feeling it could be the timing chain slapping around. How hard would it be to replace the tensioners and cost?

I found the whole kit for $220. It takes a week for delivery. PM me for the info. 100,000 miles timing chain and guides were fine. I just needed tensioners. They're $60/each. I'll find the how to link. Its really easy once you understand how it works. If you do it, i can give you some tips that werent clear to me. You dont want to set it wrong or you'll waste your heads. Two people job. You can use an extra pair of hands.

But does it sound like a floating BB? Mine did around 1600-2000 rpms. A loose chain would rattle the OHC and followers Im sure. I would make sure its not a cam follower first before messing with timing chain if you REALLY think thats it. Thats not the simplest test. I actually thought a crank bearing was loose. Scary. But it wasnt.

Ya it sounds like a rattling bb around 1800-2800 or so basically in that range. Only rattles when there is no load on the engine. Like accelerating or decelrating. Only does it when idling and revving lightly or coasting while accelrating lightly. Basically when the engine has the most slack i guess you could say. I have a video of it but idk how to upload it.

Could it be a pulley? AC clutch bearing could be shot. Remove serpentine belt and run engine for a short time to cancel that out. Read up on that process so you don't hurt anything.

If you're going to be dighing into the Timing Chain, remove the cam covers (thats a PITA) and inspect all the followers. If you're going to remove the Timing Chain cover, you can visually inspect all the TC guides. I found out my Tensioner was bad when I went to put it on and the paper clip released the passenger side but failed on the drivers side tensioner. So I found out that's what it was by chance during re-assembly. The symptoms you're having sounds like that. You'll know by the TC guides if both sides are not wearing evenly.

I also read a thread about the same problem and it was a broken TC link (on one side) but remember, TC's are not like timing belts. They last a very long time.

How does your car idle OP? Do the RPMs hang or do anything funny?
The reason that I ask is, when the Idle Air Control valve wears out it can make some strange noises.
Just something else to throw out there...

Ticking noises are tricky to pin point because the sound travels. It could be a valve spring issue. Best thing before replacing parts is to start with the easy diagnosis's and go from there. Starting to replace parts can be a waste of time and money.

We had the tranny off a few months ago and the pilot bearing looked in good shape and had no play. Car idles pretty good. Odd time it will be a little jumpy due to using defroster and alot of electronics since its winter. Ill check the IAC because i took it off a while ago to clean and maybe screwed it up somehow. I already ran it without the belt for a minute and noise was still there.

Used a stethoscope and checked the iac. No noise. Btw idk if i mentioned earlier it only does it when the car is cold. Sometimes when its warm but usually the colder it is the more it does it i just got back from a half hour drive and its barely making the noise right now. Plus its like 0 celcius out.

Make sure there's 6 quarts of oil in engine after the oil change. Half the people that changed the oil for me only put in 5 quarts. Duh.. Lol... (yes it ticked)

Noisy when it's cold...

I suppose, someone should have mentioned that these engines are quite well known for being noisy when they're cold.
I believe that I've heard it referred to as "the rattle of death" or some such thing.

The Ford engineers say that it's normal...

6 quarts when changing the oil. Check your dipstick afterwards. After a 5 minute drive. In case its off. I put 6.5 quarts after a rebuild or swap.

The tensioners and followers may not pump up properly when your low.

These engines will operate fine on 5qts of oil.
When Ford "increased" the oil capacity, all they did is move the line on the dipstick up...

Ill go add a bit and run it then check it. How much over the full line is still safe to run? I wouldnt wanna overfill it and cause problems by tryin to fix another one.
