this is the same noise my 2009 G5 2.2 makes....dealership is after replacing cam phasers and timing chain and timing chain tensioner and it still making that rattle. Any idea what it could be.???? the rattle only lasts about 2 or 3 seconds like in the video..
2011 Chevy Equinox 2.4 start up noise - YouTube

 

anyone?

 

Sounds like something is getting stuck...

 

like what???

 

Do you have any mods? Does it throw any codes?

 

no codes and all stock

 

Im not a mechanic, but it sounds like either the throttle body is getting stuck, or something is knocking in the engine

 

this is another video of the noise im having in my 2009 G5 2.2 ...all stock and no codes....already replaced cam acuators and timing chain and tensioner.....2011 Equinox noise on start-up - YouTube

 

?????

 

those videos of the equinoxs there issue is 1. direct injection fuel pump 2.def low on oil and oil is dirty gm f'd up the olm duration on the 2.4l engine got 3 in the shop replacing the engine for oil consumption problems but only the equinox...how often do you go between oil changes?

 

5000 or 6000 kilometers

 

that engine noise is pissin me offfffffff

 

check the cam actuator solenoids for debris on the screens dealer should have checked them cause there is a bulletin for it

 

they replaced the cam acuators already and still making the rattle..

 

no no the solenoids they are on top they look like two tubes with connectors on top of them

 

how do u take them out? theres one 10 mm bolt on each one and i removed the 10mm bolt and it wouldnt come out. Is there a technique for taking them out??

 

?????????

 

how do u take them out?

 

how do u take them out i removed the bolt on each one and they wouldn't come off?? can someone post a how to or a pic or a video?

 

take the bolts out. they have an o-ring type seal that may take a little force to pull out. try to pull them straight out tho without side to side movement
