My 2010 Enclave only has 17,000 Kms on it. This past weekend while I was checking the state of the air filter, I noticed a small puddle of oil sitting in the Throttle Body. I cleaned it up, and noticed that some of it was in the air intake tube as well. This engine seems too new for seals to compromised; and, the oil wasn't overfilled. Has anyone else experienced this? Thanks.
