Captain Ficho Posted January 28, 2009 Report Share Posted January 28, 2009 Car runs great, just noticed it makes some funny noises around the injectors when running. It doesn't seem loud or fast enough to be engine knock... so I'm not sure exactly what it is. It happens regardless of whether the engine is warmed up or cold. Here's a video with the cover off... you really can barely hear it when you're in person, I'm just curious what's up. http://smg.photobucket.com/albums/v74/mafiaheaven/?action=view¤t=MOV01075.flv Quote Link to comment Share on other sites More sharing options...
White93z34 Posted January 28, 2009 Report Share Posted January 28, 2009 I knew what you were talking about before I even checked out the video. Sounds like the injectors clicking away, perfectly normal as far as I can tell. Quote Link to comment Share on other sites More sharing options...
spiderw31 Posted January 28, 2009 Report Share Posted January 28, 2009 I agree... sounds totally normal. You're hearing the injectors firing. Quote Link to comment Share on other sites More sharing options...

Night Fury Posted January 28, 2009 Report Share Posted January 28, 2009 Well you aren't listening close enough! I don't like that noise, my car does it too, drives me nuts but I know it's normal. Quote Link to comment Share on other sites More sharing options...
jake91 Posted January 28, 2009 Report Share Posted January 28, 2009 i guess i havent ever had the hood open and the engine running before Quote Link to comment Share on other sites More sharing options...
Captain Ficho Posted January 28, 2009 Author Report Share Posted January 28, 2009 Even over top of the clicking though, if you listen carefully, when I get closer in you can hear a deeper knock-ish type noise, the injectors doing that too? It's two totally different frequencies, you hear the clicking clearly from the injectors firing but if you listen in you can hear a noise that sounds like two things hitting rapidly. Normal also?

spiderw31 Posted January 28, 2009 Report Share Posted January 28, 2009 Took a second listen, and I hear what you are talking about, and it sounds like the lifters to me. Since they are right there under the cams on the top of the motor, it's normal to hear them a bit as well. Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted January 28, 2009 Report Share Posted January 28, 2009 That video sucks... sorry Fil I listened to it first hand, the noise he is referring to is damn near drowned out by that video. It sounds to me like an injector. It is on pace with the typical injector firing, sounds more like some sort of seal in an injector has gone bad. the ticking your hearing is normal, I have never heard an LQ1 that doesn't make that sound.
