so i was driving my car y.day and i thought i heard a rattle so i turned off my radio and it sounded like my valves are ticking.. i did run my car at the track but its full of oil and i do my oil changes every 2500 miles anyone else had this problem its a 2006 ss sc

 

my car does this on cold start up

common prob

 

what weight oil do you use?

 

mobil one 5-30 i did my first oil change with royal purple 5-30 and then did my last one with mobil one

its not jus on a cold start its all the time now

 

check your tension on your cam timing chain

 

did you change your header recently? when i changed mine i heard ticking but it was just an exhaust leak that made that similiar sound.

 

my money is on the timing chain tensioner

 

my money is on the timing chain tensioner

 

mine does it on cold starts

 

mine does it on cold starts as well.

 

could be your lifters as well.

 

******* dealership i work for says its normal! not its ******* not and my warrenty goes out wed!!!!!!!

 

it is normal. dohc motors are not the quitest things in the world on cold startup. 4.6's in mustangs sound like that too. mine sounds like that for about 2 seconds then smoothes out when oil pressure builds up

 

read guys. it is all the time. not just on startup. free bump

 

like i said, it could be your lifters, in which case it's normal.

 

Check the timimng chain. Mine is still at the dealer. They are in a dispute with me now cause i'm fighting GM cause they voided my warenty cause of aftermarket work which had absolutley nothing to do with the timing chain tensioner!!!!!!!

It sounded like a valve chatter almost like a slightly loose rocker on a V8 or a ticking lifter sound.... Definently the timing chain tensioner. There shouldn't be any slack what so ever in the chain feel free to check it!

 

like i said, it could be your lifters, in which case it's normal.

 

i kno its normal on cold start ups but its ALL THE TIME

i got a appointment at the dealership tommorow

my buddy thinks its my cams

idk what the hell is the problem with it but all i kno is they better warranty it the service writer asked me where i have been racing at as soon as i told him i think its a valve tick so they better warranty the SOB or ima be pissed

 

^^^ If you really care it's a fen nobrainer take off the valve cover if the chain is really tight it's the fen lifters!!!^^^^

 

^^^ If you really care it's a fen nobrainer take off the valve cover if the chain is really tight it's the fen lifters!!!^^^^

 

i do care i jus dont wanna void my warranty but its all gooder its at the dealership right now there gonna cal me when they find somethin

 

I have what sounds like the same thing. I made an appointment to get the timing chain replaced. I'd check to see if it's coming from the left side of you engine though. If so, that would be my prediction.

 

so any results?

 

jus got a call bout 1 hour ago they said they have to tear down a more so they stuck me in a rental car...i should know somethin by late tommorrow or maybe friday

 

ok got a call y.day from the service writer. he said there was somethin wrong with one of my cylinder heads so they are goin to replace it the only poblem is its comin from canada so it might be in today but if it doesnt it will be mon maybe tues before i get my car back
