I am talking about the background tapping sound that seems to repeat itself.

 

Can you try this
hold your revs first at 2k & then at 3k and notice if the sound changes speed or goes away

 

Thanks for the heads up. Peace of mind is sweet.

 

heat shield or something in that area.

 

Its funny that you said this because I just finishing doing this. I couldn't tell what was going on . The exhaust and intake note block out all the noise on the header. Also once I told my wife to let go of the gas it magically went away.

 

Search for loose jubilee clips on the turbo inlet pipe

Eh not trying to hijack but the constant clicking noise that you hear on his video is how my car sounds. I have always wondered if it was an engine issue.. Someone said injectors? Is that constant clicking engine noise i hear ok?

 

hmm, you know that clicking sound from the exhaust when you turn off the engine after a 10 minute drive, it happens because the exhaust is cooling down. there's nothing wrong with it, its just how it is.

but in your case, since the engine is still turned on, I don't know what to say. but the clicking is very similar to the sound I just described. It could just be the exhaust and there's probably nothing wrong with it. I for one, have stopped listening and paying attention to little rattles and noises on the evo, I have come to terms with the fact that its normal for this car to have all those sounds. I just hope that negligence does not come back to bite me in the ***.

 

Its your plastic piece on top of your valve cover and because your in a garage. Take off the plastic piece and re-listen it'll sound normal. The cover is dampening engine sound under the valve cover but is letting one of the sounds get out so it sounds like a abnormally. The garage tight space is bouncing the sound and making it louder and more noticeable. Just a theory heh

 

I wish your theory was right. I tested the vehicle with the cover and heat shield removed when I was checking for exhaust leaks after replacing the downpipe. The noise was still there while conducting the test. The area the noise seems to be coming from is around the driver side of the enigine, close to the firewall, and close to the turbo area.

 

If you are talking about the injector pulse then yes it is normal (which is the constant clicking). The noise I am trying to figure out is the background noise. Its the clicking noise that start and stops when the engine is warm.

 

Since there isn't a performance shop over here that knows about the EVOs. I went to a mustang performance shop since they are known for hooking up superchargers and etc. They told me the same thing as you said, but he wasn't sure at all.

 

Can you hear this noise coming out of your exhaust? Like something is rattling? I started a threat about that (thats my issue) I noticed the clicky noise before I put on my exhaust but now with the exhaust its louder. The thing with my noise it goes away after the car warms up.

 

Mine does it as well just not as loud. Sound is coming for the same area on the back of the engine. I never could figure it out so I gave up.
