oil leak
 

I have developed a small oil leak. My driveway has slope to it, and I always back my panel up the driveway and it drips a few drops each time I park. So I just parked in the garage (a level place) over the weekend with a drip pan under it to see if I could find the leak. It didn't leak a drop. Checked the oil filter, no leak, and the drain plug, no leak there either. I did notice some oil residue around the oil pressure sending unit, is it possible this is my culprit? Any help would be greatly appreciated...I hates oil leaks.

Very good chance.

Mine has a similar leak. Read this first part of this thread. This is my issue. However it's been leaking maybe a drop a day since about 90k miles. Never got any worse. It currently has 155k. I replaced the oil sending unit and that was not the issue. My leak is on the crank case seam just above the oil sending unit so that it looks like it's coming from the OSU. Strangely enough it does not leak in summer, only during cold weather. Also the leak slowed when I switched to synthetic oil. It doesn't really lose enough oil to have to add any on a regular basis.
