I noticed that my wife's G35 leaked a few drops of engine oil on our garage floor over the last week or two. Not much, probably 7 or 8 drops -- I don't have a lift so I did the best I could to take some pictures.

I noticed a oily spot on the drivers side, but it doesn't appear that is the issue.

On the passenger side, and from the front I was able to see a bigger issue. I wasn't able to remove the bottom cover (not climbing underneath with the cheap tire jack...), but noticed quite a bit of oil underneath. I was hoping from the pictures someone might suggest the severity of the issue. I checked the oil w/ the engine cold and it was about 3/4 'full' -- so I assume the underside is probably not as bad as it looks.

I'd appreciate any suggestions, I initially thought it might be the oil cooler seal -- but I'm not sure if the amount of leakage matches. Anyway, I know the answer is probably "not enough information", but I thought it was worth a shot. I'd like to have some info before I take it to have someone look at it...

 

Could be the oil cooler gasket, lower or upper oil pan. The gasket is easy to change along with the lower oil pan gasket it's made of RTV. The upper oil pan is also RTV, but not as easy to change.
