Engine ticking noise *vid*

Had this weird very quiet low pitched tick the year now I've owned the car. It only does it when it's cold and totally goes away when it's warm.

Lately, I've been getting a tick once the car is WARM, opposite of before. It ONLY happens when I'm just BARELY on the gas, and above 2k rpm, like you see in the vid. If I give it anymore gas than JUST a little bit, the noise goes away.

Little background - had the engine out the beginning of May and replaced the rod bearings a piston (new rings and wrist pin on that piston) and replaced all the gaskets. I took the car to Ford a week ago and they say they "think" it "might be" a timing chain tensioner. Idiots.

It sounds a little more serious to me. It's not rod knock because it's not there all the time. Could this be valve train noise? It's just weird that it goes away as soon as I give it any more than a little bit of gas.

First thing to check when you hear "a tick" is the tightness of the spark plugs. Do this when the engine is cold.

If one is loose it could blow out so check them ASAP...

I will right now..

ENGINE MUST BE STONE COLD

Do not overtighten the plugs, torque spec is 8-12 foot pounds I think not absolutely sure though...

Checked all the plugs, they were all tight. Took the one out in the cylinder that I fixed back in May, the plug looked fine.

I had a similar problem in my old 89 camaro that I used to have. It ended up being a broken bracket. I can't remember which one it was, but the pieces were clacking together when it was cold. Heat makes metal expand, so the sound went away once it heated up. I kind of doubt this is your problem, just because of the way you say it does it under certain RPM's also, but, just to be safe, maybe you should check ALL of your brackets, mounts, and pullies for cracks or broken parts. Another time I had a similar problem (same camaro), it was a loose valve, and since you DID have your engine apart, that would be a possibility.

Could also be an exhaust leak...

but it wouldnt go away on a warm engine.

 

[Kilgore Trout]

Sure it could be, if it was a minor one it could go away once everything heated up and expanded.

 

[Skidzz]

That's very true. He said that lately it's been doing it when it's warm instead though.

Yea, it does one kind of low toned clicking noise when it's cold, but now when it's warm that goes away like usual but now there is a ticking noise when it's up to operating temp like you hear in the vid.
