2003 c5 timing chain history
Hello....Hopefully I can get a few replies that shed light on '03 timing chain life. Yep..I know some go at 50K...some north of 200K. The variables are many ie service and abuse/abuse.
I still assume there's an average or typical that the reader of this post may have feedback on and will pass it along. Thank you for reading...Mike

Timing chain life time is dependent on how the car has been driven, my opinion is to change it once it goes over 150k, best to change instead of having it skip a few teeth and ruining the engine.

Actually, if you research "LS harmonic balancer removal/replacement", that will cover a good portion of the work involved. Once the balancer is off, it's just a matter of removing the front cover of the engine, and accessing the timing set. Replacing the timing set isn't the hard part, it's all the disassembly that you have to do, in order to get to it.
