Post-AOS oil leak

[Auf los!]

In eight years my car had never leaked so much as a drop of oil, until the day this January that the AOS let go in a big way. Major smoke screen, cylinders got hydro-locked with oil, repeatedly stalled, had to be towed. There was a puddle of oil on the flatbed tow-truck.

Had the AOS replaced, and the car runs fine, but I am annoyed that I've been dripping oil every since.

I will be looking for the source of the drip soon, but can I get some clues as to what it could be, and where I should look? Thanks!

Maybe AOS is not completely seated? The other thing in that area that is suspect is oil fill tube, but it usually causes a vacuum leak.

Don't get frustrated! These cars are amazing! Think about it, your car is 17 years old and finally has one little oil leak! I get it. I'm proud of the fact my 2000S has no leaks. I've had one before, from a couple of oil tubes but that's about it.

Well, start with the AOS oil line at the top and the return at the bottom. Check to make sure that the oil line at the top is firmly attached and that the lower return pipe is fully inserted into the block. The lower return line is not a typical leak source since the AOS return is fully pressed in when the AOS bolts are tightened down.

Other typical oil lead candidates are the RMS, IMSB seal, spark plug tubes, oil fill tube, and cam covers. As dghii suggested, the oil fill tube is worth checking since it is right next to the AOS. Otherwise, it would be strange for one of these locations to start leaking just because the AOS was replaced.
