Hello all, I am new to this site but I couldnt think of another way to try and figure out my problem. I have a cts 2003 engine and it only has 85k. all of the sudden the engine literally started sounding like a diesel truck. I took it to two mechanics and they say the engine is blown and they arnt really sure whats wrong with it, but the car still runs, they just dont know for how long. Does anyone know what this could be? I cant afford a new engine and was thinking that maybe it was something smaller to fix. If anyone knows anything or has any suggestions PLEASE let me know. Thanks!
