Few weeks ago I found out that there was few oil around the drain plug while I started the car in the morning. Also, there was few oil dropped on the floor. But it wasn't smell like engine oil. I tried to re-tight the drain plug and clean everywhere underneath of my car. During few days after, I didn't find anything like that happened. However, what I found on last Friday was that there were still few oil on the drain plug and the area around it while I parked my car in the parking lot. Then I cleaned it a bit and test drive it and try to find out where is the leaking at. Then what's worse I smell something plastic burning around the intake manifold. Anyone get ideas about it?

 

Is this on your Mustang or an Evo?
What's the year model of the car? milage?

 

lol my bad. 05 evo 8. motor millage 40k

 

Guess you could try the dye and then trace the leak yourself. It's a lot harder without a lift though.
Have you ever separated the transfer case from the car?
Also, did you replace the drainplug washer?
