Hey Guys,

That could be anything man... Try to get a video of it, do you know the general area it is coming from on the car? Engine bay, cabin, rear, etc...

I agree it could be anything from how you've described it. But keep in mind these 4.0s are known to have very noisy fuel injectors that tick or rattle, so your issue could be just standard operational noise. Are you sure its coming from the engine?

+1, but he said he doesn't hear it at idle which is the only time I hear mine.

Ahh good point! I thought I was going crazy because whenever I pulled up to drive-throughs it would tick like crazy, then mysteriously die down once it got off idle...

OP have you done the basic checks like oil/fluid levels?

Yea everything is Good , all my fluids are good level.

My mechanic told me its not a big thing ... Probably Injector...

I will keep you posted .

My 4.0 (2007) with a 100k just started making a really bad rattling sound somewhere around the top of the engine. Sounds like something broke or came loose. I had a mechanic look at it (not sure if he's any good) and he pulled off the valve covers and the plenum and the intake man and he could not find anything wrong. He said the injectors were ok.

I'm desperate. If I can't identify the problem, I will have to let the car go. Can anyone shed some light on what could be making such a noise? I initially thought that it was in the timing chain area but it's further back. Thanks.
