Oil Catch Can?

[Chiketkd]

From when I owned my 300ZX TT in college, I know that on most (maybe all) modern cars, manufacturers will include an oil catch can.

Since switching to Mobil 1 10W-30 my car had no leaks for several weeks but recently I noticed a little leak coming back. However, this leak only started after a very 'spirited' drive along a twisty road on the way home from work one day. Since wiping away the oil, and driving my car (like my wife would ) I've noticed that the leak has gone away...

My question is this, does the SVX have an oil catch can? Could our engines possibly 'leak' as a result of a series of high lateral g turns? What could have caused this mysterious leak?

A bit slow catching-on to this endearing Subaru characteristic, aren't you?

Pardon my ignorance, but what exactly is an oil catch can?

This is a description of an aftermarket one from Greddy for the WRX: http://www.subarustore.com/gredoilcatca.html

An oil catch can catches all the crankcase blow-by.

I had to buy one because my car didn't come with one and I don't think the SVX's have one either.. I know when my car was fairly stock I didn't have a problem with blow-by, but when I increased boost I would notice oil around the outside of my BOV so I got a catch can and fixed that.

For some reason, I think the seals near the top of my engine are leaky which caused oil to drip when I was carving up roads (also having 7.5 qts of oil didn't help).

I realized my engine was overfilled this am when I checked the dipstick and drained 1.5 qts, then added back new Mobil 1 until the correct mark was reached.
