Question Condensation in crankcase from cold weather?

It has become pretty damn cold here in San Diego. While checking my oil level last night, I noticed that my OCC [oil catch can] for the front VC looked noticeably different. In fact, I was alarmed because I immediately thought that my VSS/HG took a huge crap w/o me knowing.

Typical/"Before":


Unusual/"After":


My car does not have any of the symptoms for bad VSS/HG. The oil is fine at intervals and there is no strange smoking problems. I searched a bit and discovered that condensation can build in the crankcase in cold weather from not being "burned off." This supposedly occurs from short-distance driving that does not allow for a hot engine.

Yeah you might start to notice some on the underside of your oilcap too. Nothing to worry about though.

Where did you install this catch can? also what kind of a catch can is it, looks kinda weird?

I am kind of interested in that catch can setup my 3s does not have one, what are the benefits and or reasons to installing it in that spot and what kind of a cc is it? Thanks!

Thats normal for that to happen, like others said you will find some on the bottom of your oil cap also. And yes short driving will deffinatly do that. bikes have a glass window from which you can check the oil and my gixxer window looks like that when I go on short drives. But after I go for a ride its obviously gone. Also different types of oil get more "water" in them over others, andother reason to not only change oil every 3000 but every 3-4 months.

They are also famous for the damn sludging lol, rebuilding a motor now because the pickup tube and the pump were fubar hence no oil going to the top end!

Haha you guys are soldiers handling that weather. Well I am glad to know that this is normal.

BTW, I made my own catch can from an air compressor filter + ss lines. I used to have one for each VC with the Krank Vents, but the front one ended up filtering all of the bypass gasses rendering the rear useless. Basically, it helps to keep your intake free of buildup. The most common spot is your rear turbo's intake runner.
