This is my first post on StangNet.
Sorry if this is a repost.
Any ideas or help would be greatly appreciated.
The car is pictured in my avatar and is an '06 GT with 20k miles and still running the factory recommended 5/20 synthetic blend Motorcraft oil.
The problem is a loud rattle/clatter noise from under the hood under hard acceleration that begins at 4k rpm's only when the engine/coolant temp. is in the cold range. The noise does not happen after the engine/coolant temp has warmed into the warm/normal temp. range.
To me this noise sounds just like and old push rod V8 valve rattle.
I went to the dealership I bought it from and asked if they had any tech. bulletins on this or have had any other complains like this. They said "no not at all" and suggested the noise I was hearing was due to the car/oil not being warmed enough to allow for the valve train to be properly oiled and suggested I change my driving habits... I thought that this was TOTAL B.S.
Anyhow... I've done some reading on this problem on the Internet and have read it could everything from incorrect valve lash to a bad factory engine tune.
I'm going to take it to the dealership tomorrow mourning and let it cool down and then take the service writer for a test ride to show what I'm talking about.
Any ideas from anybody?
