Ok, I've been smelling burning oil and have noticed a drips on the garage floor...not enough to cause alarm and there's no visible smoke when driving. Here is a pic of something odd I noticed that would explain the lack of smoke from the tailpipe, but the noticable smell in the cabin, only problem is I have no idea what the part is (that is labeled OIL LEAK? in the picture). There is oil visible on what I can only assume is the head. *I haven't done any in depth work on flat fours, but have had numerous turbo cars. I guess I'm hoping some one can identify the part in question or can share a fix if they've had similar problems. I have had no performance loss and no noticable drop in oil level. My guess is it's a sending unit but it's a very odd location for one. The picture is between the intake manifold and the IC. Any input is appreciated. Thanks.
