Are Oil traces on the bottom of the vehicle a sign of a serious leak ?

The oil isn't dripping and I'm not losing oil (not in noticeable amounts anyway). But yesterday I went under the car to replace the fuel filter. I noticed that the ares where the Oil Level sensor is located is a bit greasy.

I know I should replace the gasket of the oil filter housing , its not leaking badly, but I'll replace it anyway. What other possible oil leak sources should I be looking at ? (Valve cover gasket, Vanos oil line ...etc )

Thanks

Pools of oil are a sign of a serious leak, traces of oil are for any practical purpose, normal. Depending on how large the trace is, ignore it. Whether you elect to ignore it or act against it, there is no rush to do anything. Take your time and formulate the appropriate action plan, acquire the necessary parts, then go at it.

@OrientBlau. Good advise ! I have an oil change coming up soon, so I will do that , replace t he vanos oil line and the oil filter housing gasket and rubber ring, then see if any oil traces are recreated.

@jdstrickland: I think I will tackle it early before it becomes something serious. Thanks for your time

go to wrench it on 1300 S and 700 W. it is a diy garage for about 12/hr you can get your car up on the lift and go to town on it. either that or my friend manages the holladay jiffy lube and will let you walk down in the bay . let me know if you want to work on them soon. we are doing my brother's e36 trans fluid soon at wrench it so maybe we could make a day out of it.

Clean it up with brake parts cleaner and check a few days later.

That Wrench it shop is Nice! too bad they don't have one down here in orem-provo cuz there is nothing I hate more than jacking my 325Ci with my low clearance lame Walmart bought hydraulic jack and then squeezing under it while the ants feed on my skin!!!.

I Just replaced the Expansion Tank, Fuel pump, Fuel filter and front control arm bushings ... and I have an OEM alarm system and a DICE Mediabridge to install. So I'm giving myself a break for now and I'll tackle the oil issue early August.

I have an Oil change, serpentine belts and pulleys replacement, oil filter house gasket replacement, vanos oil line replacement and spark plugs replacement to do all at once! I will probably do all that August 10th or so. I'll PM u then and see if u have stuff to do as well.


@Solidjake: I think that's what I'm going to do.
