I just bought an 05 c6 and the dealer left it two quarts low. On my way back I started hearing noises already.

Heres the noise i'm getting now:

It seems like you cant hear it inside but unless the car is engaged.

Is this a rod knocK?

sound like lift tick to me, did you put 2 quart back on ? hell I TAKE IT BACK TO THE DEALER ASAP.

Yeah, has lifter tick too (common). I changed the oil after adding 2 quarts. I'm worried bout the deep tone'd ticks in there.

What oil and filter do you use ? like I say early, if I was you, I take it back right after I find out it 2 quart low.

The noise came before the oil change, I added Mobil 1 5-30w when I found it low.

And the oil change was Mobil 1 5-30w, AC delco filter. Didn't help any

My 05 C6 got a split cylinder wall at 30K miles letting coolant in. Started knocking afterwards.

What? How did that happen? Not from normal operation I hope.

Not sure, I had only had it 2 months before it happened. I never got a chance to abuse it.
