Default oil catch can content

Less than 200 miles since I installed the catch can and this is what is in it.
This is a stock LS1.

I think that I do not know what this stuff is.
I also think that this is a lot of what ever this is in a short period time.
Shouldn't this be black oil and not like gas and oil and water mixed?
This is almost a quarter of a cup of liquid.

LE sigh. Nothing wrong with that. Condensation creates that milk shake. Normal.

I have an Elite Engineering catch can on my car and have never seen anything like that in the reservoir. Every time I check it just has black oil in it.

To catch oil that is pushed out of the crankcase that would otherwise be blown into the intake via the PCV to be burnt.

The oil on the dip stick does not show the milky condensation nor is it black.
The DIC says the oil life is at 56 percent.

Many years with my can, never any milk like that.

Obviously there is moisture entering somewhere.

If you are not losing coolant you have nothing to worry about. Longer drives would clear this up.

Short heat and cool cycles cause this. You need to run the engine long enough to burn off the condensation.

I get this in my truck on the oil filler cap when I only drop my kids at the neighborhood school then switch cars for work.

If I remember I'll check my catch can before I drive today since I've driven a 250 mile trip interest last few days.

Thanks for the replies everyone.

This is the first dump and my daily driver so I will see and know more next time.

How often is everyone checking theirs?

I did search but nothing came up.

Is mine set up correct? I looks to be different from your set up.

I have the main line going to the can and the top line pulling through the mesh filter and then PCV check valve into the intake.

The rubber factory elbow was rotten and blowing oil in the bay instead of the intake is why I got the can to begin with over a year ago.

I lost the instructions or the name of who makes this can.

Nice picture by the way.

bottom to intake, top to drivers side ( back of valley cover) Keep in mind there is vacuum pulling... so it is very important to have everything routed correctly. good luck.
