Rear Main seal leak.
 

Looks like the monte has a new issue. Its leaking oil i believe from the rear main seal. It has also had both dome cover gaskets replaced. Come on chevy you are starting to disapoint me.

Good thing its still under warranty. As long as i do not have to pay for it i guess i really dont care lol

How much oil is leaking? I doubt theyh will work, but there are $10 bottles you can buy and pour in your oil that may stop it for a short time period.

Good thing you have a warranty. When my buddy had a new car with a bumper to bumper warranty he took it in before it was up and got everything fixed. There were a lot of little things that most would just live with like the color was rubbed of the leather seat, A few plastic carcks and some other things. The dealer fixed it all for free.

Its not leaking much oil. Looks like it just started to leak. There has just been alot of engine problumes with the car. ESP when it is under 60,000 miles.
