Somebody please help me out. Anybody that had there timing chain replaced for a TSB. I want more information on this due to the fact the dealership wont do anything to my car unless i take the motor mounts and trans mounts out of my car first. I wanna do my Stage 3 this weekend but my car is F'd up as it makes a screeching noise at idle (sometimes) The dealership drove it and didn't find anything (like i thought they wouldn't) and said i hafta undo the mounts. I'm looking for a TSB number from GM and came up with nothing. Anybody with more information please shed some light on this for me I really appreciate it.

and figured this might be my problem:

 

I had my timing chain tensioner replaced after 1 month due to a chattering noise in the crankcase

 

do you know of any TSB # for this or any other information...

anybody??? come on... i PM'd several people with no response doesn't anybody wanna help out a fellow ss.net member??

I called GM and got this freaking guy that doesn't even speak English right... so i hung up and called back... i got someone else and let me tell you... I think it was a total waste of time... The are no help at all... I guess I've gotta take my motor and trans mounts out tomorrow and then take it back to the stealership to have them ******* fix it and don't want it back until it is fixed. Fin A holes... I hate dealerships i should just buy a bicycle

 

PIP#4014 all this states is there is an updated design because of old design flaws and tells service techs about the o-ring that needs to be swapped. Nothing else

 

PIP#4014? thats the number?

 

yes it is a preliminary info GM doc# 1884273 all it states is there is a o-ring you have to switch over when doing the timing chain because of timing chain failure or tensioner failure.
