Leak help?
 

I just changed my oil the yesterday (for my first time) on an 05 WRX. I used Mobil 1 Synthetic 5W-30 at 15k on the odo. Everything went smoothly except for the fact that after I put in the oil, I noticed that the dipstick didn't seem to have any oil on it. (I put in about 4.2 quarts of oil in) Jump to this afternoon. I'm going out to grab something to eat and notice some kind of leak on floor. I touch it and smell to see if its oil. (yes it is.) I look under my car and see a bit of droplets on my undercarriage. I check to see oil filter and drain plug (both of which show signs of leakage.) What do i do?

tighten them both, check and top off the oil - if you re-used the crush washer (or left it off altogether) that could be why the drain plug is leaking.

OH OOPS. I Made a typo, I meant to say NEITHER OF WHICH show signs of leakage. I DID replace the crush washer....and im just *huh'ed* by this situation.

I would get some brake cleaner and take the oil off the ground where u usually park. Park there overnight and check to see if it's actually you that's dripping.
