I had a 2006 GTO LS2 with a minor oil leak that cause a smell. GM ended up replacing the engine claiming a porous block. I hope not to go there again!
Exactly, when fresh air is on is when it smells. I so hope this is not some engine issue. I know a couple ZL1 guys had a smell and needed their rear main seal replaced. I am going to forward this link to my Service Manager (who has been great with my issues) to read again. I am also going to message Brandon from GM customer service to document our issue. I'd like to keep this fresh on the minds of everyone so GM can come up with a fix.
