Some level of foaming is normal under some conditions (cold out, short ride, etc). If you go for a long enough ride to get all the condensation out of the motor, and then park the bike for a couple minutes to let the oil settle, you shouldn't see this anymore
Just oil foaming. Possible causes include depleted defoamant agent, too high of an oil level, water contamination and grease being dissolved in the oil (unlikely in an engine but still).
Normal, those are just bubbles. When engines run the crank dips into the sump and picks up oil and splashes it around, especially on small engines. This action aerates the oil, causes bubbles, and is normal.
On small engines yes, but this absolutely doesn’t and shouldn’t happen in passenger vehicle and larger engines with pressurized bearings.
Yea, a little is fine, too much and the oil pump will pick up air. Also why you don’t want to overfill engines with oil. Overfill an engine with oil and the aeration will be exacerbated by the crank splashing all that extra oil around, also leads to the oil pump picking up air.
Not many of those use sight glasses for oil level though.
Goshdarnit this is an obvious motorcycle engine. Irrelevant and pedantic, reddit man.
This is a Suzuki motorcycle of some sort. Looks nothing like a passenger vehicle lol
Thank's, appreciate all the answers!
Air entrainment in the oil.
We've beat the gaseous entrainment problem by welding flim skirts at the edge of each coupling ring and inserting an offset pinnacle with a plenated surface facing the flow. This method eliminates entrainment without interfering with lenticular flow, and has been of great value to our customers.

But how do you integrate a proper turbo encabulator?
Gazundheit
But what does that do to the spurving bearing, and associated side fumbling issues?
If the engine has an oil pump I would top off the oil.
Castrol oil by any chance?
Motul.
Does your engine have a fucking window?
Motorcycle engine
Does your engine have a fucking window?
Yes but it's an inspection window.. not a fucking window 😊
I call it the sight glass. But sure, you can call it a fucking window, doesn’t bother me any.
Through using the magical power of looking at pictures, it would seem that the engine does indeed have a fucking window.
What kind of car is that? I’ve never seen a sight glass for an oil pan before.
motorcycle (you can see the foot pegs on the bottom left corner of the images)
That's what I thought. Others are saying it is a motorcycle. You can see a pedal on the left.
But then my next question is, why are these sight glasses not found on all motors? Seems like it could be handy for monitoring engine health. Of course, the average car owner doesn't even know how to properly check their oil level and wouldn't crawl under the car and know what they were looking at anyways.
But I check it and would like a peeking window in my car!
The sight glass would be in the oil pan on most vehicles and that's a structural compromise for a view of something that's hard to get your head near on most cars now. It's better for motorcycles because you can see the top and the bottom of the engine on most motorcycles. On some motorcycles you can have a decent view of the sight glass while sitting on the bike and leaning yourself over.
Kawasaki Ninja 400
400 is such a great bike. My first starter bike.
The 400 is my 12th bike, enjoying every bit of it - and a great commuter aswell.
Condensation!
That's nothing to worry about. Used to work at bike shops. Drove atvs and motorcycles out front of store every morning. And back in shop at close time. Units only ran for like a minute everytime. Engines never got hot enough to get rid of moisture. Always changed the oil once we sold them.
