This is what I see from the oil cap.

Is it normal ?

I don't think you have to be worried.

It's been very cold. Moisture will condense on the cap and give you that milky appearance. It should burn off after a nice long trip.
 
What engine/history?

The photo seems to show a baffle under the fill hole. Just because it is crudded up doesn't automatically mean the rest of the engine will be.

Yes you are right, made a mistake,it is the fill hole.

The engine is Kia 2006 2.0L on kia spectra.

Thats not yellow slime from moisture thats the baffle with the black crude scrapped off.
 
I would scale back your OCI to 15k and check oil condition with a UOA. Might be nothing, might be something but can't be sure just yet.

After looking again it does look like areas of the baffle missing pieces of sludge. The black edges are sharp and clearly defined."Mayo" just doesn't look like that.

No.

The car goes very good so far.

I was thinking that can be an issue with PCV Valve since I never changed it, now the car has 134.000 KM the first 5000 I did with factory oil, after I put the kia dealer oil Kendal changing every 5000 km.

The car was going horrible with that oil since the first kilometer, horrible oil.

So I changed when the car had 20.000 km to petrocanada synthetic and the car just changed totally.


I used this oil for 30.000 km with OCI 12.000.

Than I changed to Amsoil with 20.000km OCI.

You are right how do I move the post ?

It's a layer of thicker particulate matter. More than just varnish.

No

I would bring this matter with Amsoil.


Is it possible that is PCV valve issue ?

Yes, a clogged PCV will only accelerate deposit buildup, but it had to get clogged by something in the first place and the only thing it can get clogged by is oil by products.

I dont think you described your daily commute and how the car is driven in general, but judging from your low mileage and the build up, it looks like the oil should've been changed more often.
Short trips, especially during Canadian winters, will put lots of fuel dilution and moisture contamination onto the oil. Synthetics don't deal any better with these contaminants and sometimes have to be changed just as often as dino. Since you didn't do any UOAs, it's hard to say what the optimal OCI for you driving style should be, but the current one is too long IMO.
