I suspect its from a different place but I don't really know. It just seems so unlikely the tha main seal would be leaking again after two shops checked it in such detail.

I'm thinking that the oil leak problem happens after the car has been driven. Both shops checked that main seal, and I remember Strictly telling me that after fixing it and letting it sit there overnight, the car was bone dry underneath it the next day. Driving it home and letting it sit overnight made it leak all over again. One thing I did notice though is that the leak does get much less over time. For example, I took the car home and let it sit overnight. Next day I put a cardboard underneath it and let it sit undriven again for another night. I checked underneath it the next day and it still did leak, but very little, just a few drops. For these reasons I'm thinking that driving the car makes the leak happen alot more, and letting it sit there makes the leak settle down somewhat. I'm going to describe this behavior to the guys at the local Chevy dealership and see if it gives them a clue as to what it could be.

 

Got a new follow up on this. I brought the car to my local Chevy dealership and had them diagnose it. They figured it all out in 1.5 days. The AC fix was easy, apparently the evap temp sensor was unplugged. The also found that the passenger side valve cover was bent and wasnt sealing right so they fix that. Thats the good news.

The bad news is that they sort of confirmed what Haddad had feared early on. Basically, they changed the oil pan and made a fresh seal. Left it overnight and it was all bone dry the next day, exactly as both other shops had found out. The problem Chevy says is when you start the car. They told me that there is piston blowby which is causing excess crankcase presure, which then basically breaks the oil pan seal every time. The good news is that the explanation makes sense and explains exactly what i've been seeing all this time. The bad news is it means the motor is bad. Don't know what to do at the moment, but at least the issue has been figured out ;(

 

Whatever happened with this? Is the car running ok now?

 

I gave up and bought a new car. The Camaro sits parked now with a car cover on it as it's out of action until it gets a new motor. All payments to that shop were made via credit card so I contested all charges. I also have free legal available thru my employer (Take Two) and my wife's (Microsoft) so I'll use it if I have to. I've had enough and I intend to fight this to the end. I don't like that it's come to this but I feel I have no choice.
