i am new to this forum,i have a 2008 sts with 79k and having issues with the timing chains,i have it at a gm dealer and the recall was never done,the dealership was going to fix the issue,but have stopped stating metal remains in the engine and stated not enough oil changes,i have looked on a lot of sites and they refer to the sludge build up on the right bank
can some one give me a direction, thank you
