i am not going to give up on my ss s/c, but i will tell you that my 2.4 never had problems!!!.
most of you know that i have had a lot of problems with my car before and it ended up to be the catylic converter which was fixed under warrenty :) but now i have THIS!!!! http://youtube.com/watch?v=nEPw78lAPl8 can someone tell me what the hell is going on here?!!!! also, after i had the catylic converter changed out i requested a re-learn on the pcm and they said no!, that the os was up to date and nothing would change on a re-learn... after i had this noise i took it to my gm dealer and asked one of the guys at the service desk to take a look at her ( right out the door) and he said no, that it would have to make that noise when it came. i told him that it probably wount becuase everytime i go to the dealer they say its fine :cussing: first! anyone know what this problem is? second! advice for the dealer! |

sounds like a leak or the cat is fucked up... buti can't be sure ^^^^ i dunno about tha ti thought that initially too but once he moved the camera to the back of the engine by the header it got louder
|
Oh yeah i forgot this it could be one of your fins inside of you supercharged that broke off thats what happened to mine before and i got the dealer to get another one
|
sounds like either a floated rocker or fryed piston ring's.. that is NOT normal.
|
well here is thie thing. that noise! happens at a 60/40 chance. yesterday it didnt do it. after i install my ingalls today it started all over again. doesnt seem to have any problems at boost. where ever i can grab traction that is. i just got back from my local walymart. and it started sounding rough and the exhuast didnt sound to goo either......
i think it got louader towards the header becuase the mic got closer to the top of the head. its was really loud where the plug are |

sounds like something rattling...my car made that EXACT noise once. Know what it was? I blew a little holes in the top of the DP and little pieces of metal rattled around in there. It got louder with more power. Well eventually my car ended up sounding like a race car cause the hole got so big.
I sorta feel like its just something loose, cause everything everyone else mentioned SHOULD throw some codes. |
=O
holy hell mine sounds the SAME way too only at times tho...and its freaks me out but its not THAT loud. i always thought it was the supercharger working more because it would be louder for me at the pulley itself. if we scan the car with HPtuners, would HP tuners throw us a code maybe? |

to elec blue. my first post mentions that i took it to the dealer when it was really loud and they wouldnt look at it!!! period. and the reason is and i qoute "it has to make this noise when the mechanic looks at it"
to everyone -> um, something broken? first i thought that this could be an advabnce retard but then thought that it should have corrected itself. i will be hooking it up to a scanner tommarow but i doubt i will be able to get anything since gm has built these cars that the cel wount go off for Major problems..... it didnt even go off intell 3 days after by cat blow apart. it might be just me, but it seems gm avoids everything to do with the lsj's. like they know something i dont! this is the only car i have running at the moment, so parking it isnt an option! anyone else have any other thoughts? |

is there any oil in that fucking thing?!
|
ya check the heat shield and if thats fine i would be money that its your timing chain rattling around.
|
haha, i appreciate the advice everyone. but really if you listen to the video that is definatly not a heat shield!. i was thinging something to do with the timing, but its hard to say. i am having trouble with vids right now. but i will post more tommarrow. it goes into gm on the 19th. but with this problem, i want to see if anyone can reconize this problem, so when i take it in, i generally know what i am talking about.
um, i left her running and went outside and rev it up slightly a couple times and noticed that the computer had a hard time with idle down after the rev. i dont think the -32C temp is helping, but since the car is warmed up i dont think this would be a problem. so loud noise in valve tran area weird exhuast note hard time idle after rev the only thing i can come up with is sensor timing or more dissapointing broken parts, but i dont see how this is since its been different behavors over the last week or so. so warn parts at 17k? hahaha, i dont think i have good luck with these balts :p oh and yes there is oil in the vehicle. this also brings up on another qoiute from the serrvice guy! "sounds like oil trouble in the head" <-HOLD ON A SEC.....is there a typical problem with this? what directs the oil into the head on these balts? anyone know. only 2 main methods i know of to get out around the engine, crank splash, and oil pump |
It sounds really bad.
Sounds like you have a Diesel SS/SC :p Seriously though, get that sorted out before you put more (highway) miles on it. Please keep us updated on this so we know what to do if/when we encounter the same issue. Don't give up on the SS/SC !! . |
sounds expensive.
Take it to a different GM dealer, tell them your having problem with a different problem or that you had work done on the cat and you think the heat shield is rattling to get them to actually look at it... The GM dealers around me are like what you said. One place won't even look at it if it's got so much as an aftermarket antenna on it, and another dealer would let you roll in with the valve cover taken off and act like it was no biggy. |
Sounds like a lifter not pumping up to me almost. Just my thought, and or the top end of your valve train starving for oil !! I'd recomened not even driving the car untill it is fixed if you can help it !! Get someone to check the oil pressure on it when the noise occurs !

supercharger bad
