Burning or leaking oil
so ive had the car for about 6 months now.. 3 months in i got the message add 2 quarts. so i did and then a month later changed the oil. now i just got it again so its been about 3 months since ive changed it and probably a little over 3k miles and i got the message again and i can smell oil once in a while threw my vents. usually when i come to a stop. then today coming home from work at a stop light it looked like there was a smoke coming from the vent in the hood,nothing major, but smoke none the less. the car still runs great and cool though so i decided to look into it when i got home. took the top off and also got underneath. from what i could see underneath it looked like some oil on the splash guard but didnt take it off it was too crammed under there. as far as up top the only oil i can see really is where the fill cap is. is there anywhere i should check in particular for leaks in the m112. ive read some stuff about the breather and some hoses. theres a pic of a hose what looks like someone put some seal on it and did a messy job

Mine leaked/weeped at the rear main seal. There's a rectangular plastic cover at the bottom of the trans bell housing that it leaked through onto a plastic shroud/cover beneath the transmission. After 175K miles it never leaked enough between changes (13Kmiles) to cause the add light to come on though. If smoke came out of the hood vent I'm guessing oil is leaking onto the exhaust headers/system someplace. A common leak point is the breather covers on the valve covers.

The C320 has a GREAT cabin filter. Double carbon filter about 4" thick. If you haven't yet....replace it. You need to activate it from the HVAC unit. I just left mine on always and never noticed any fumes.

Yea I leave mine on alot it is great but I'm wondering if I need to replace it because I do smell the oil fumes once in a while but then to test it I turn the filter off and it's harsher so it defiantly works lol
