Oil smell inside C230

I have a 05 C230 Sport. I keep getting an odor inside that I think is oil> I have had it to the dealer atleast 4 times with no results. They tell me they fixed a leak but I still have the smell. At first they said it was the ac.I am going crazy with this. I had it to the dealer 3 weeks ago and again they said a leak was found.. I cannot see any leak, i can't smell it in the garage , but I smell it going down the road. It smells like a worn out engine [blow by]. this car has 50k on it. Any one else had this problen???? If so what is the fix?? I am finished with the dealer... thanks khuffy1@msn.com

It may be engine oil you smell, if whomever changed the oil and overfilled the oil it can come out the throttle body. I doubt a/c oil smell would be that strong. (wondering if they leak tested the A/c?)
I have an older benz with a bit of blow-by which actually is normal due to the nature of the emssions recovery system, (reducution of pollution) it may just be a case of cleaning the throttle body. B

I would go to a different dealer if you can. That is kind of fishy everytime they find a leak, but no improvement. I had the same problem with a dealer, transmission was done for and they kept saying oh it's fine.
