Today i opened my hood and was just listening to her run ....... idle that is, i wanted to make sure there wasn't any strange noise that i might have occurred lately . Lone and be hold i'm hearing something strange . i believe it's from the Valve or somewhere in that area. as the engine is idling i hear the clicking noise that's normal but another sound is emerging .... like a fluttering sound going up and down as the engine is just sitting there. and no , no one is stepping on the throttle this whole time. just a pulse of fluttering back and forth from the valves or somewhere from the top of the motoring..... anyone knows what this is ? or is it just normal. The last thing i had done 2yrs ago was a boost gauge. i can see the line the connected from the fuel rail to get the reading but other than that everything seems normal. any advice or opinions greatly appreciated. Or am i just being paranoid and the sound is normal when you have turbo with a boost gauge .

 

by the way the noise isn't really loud just very noticable when the hood is popped open.

 

normal, welcome to 4g63

 

correction .... the noise isn't a fluttering anymore it's more like a rattling sounds / you only hear it when the hood is open and also the noise is defintly comming from where the injectors are any guesses what it could be rattling sound not a ticking sound i am aware that the ticking is the injectors but the rattling is brand new. i've had my car for about 3 yrs. now and have never hear of this sound before.

 

If it was a honda Id tell you to get the valves adjusted but the EVO's self adjust. I dont worry about rattles like that I just attribute it to this being a turbo sports cars and its normal.

 

that is excatly what i was thinking, when that happend to my honda i just got the valves reset and it quited the engine but since this is my first Evolution i was concerned. But i do admit after getting a Flash done to the ECU i know if anything were to happend i don't think any Cel would pop up giving me an engine code , because i was told i lose that information for the ECU once i got the REFLASH.....

 

No youll still throw cel's with a flashed ECU. I dont think your car has any serious issues but you could always pull the valve cover and have somone check it out.

 

thanks great advice i'll do that

 

when you pull the vavle cover off do i have to re-oil anything or will the seal be ok / what i'm getting to is i use to take my valve cover off my Honda Integra and just put it back on like no big deal . i would do this to swap with my friend's ITR red valve cover. i didn't buy a new seal or even oil the valve either just put it back on . Now for the Evolutions is it any diffrent ? seeing it's a turbo engine
