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.

what is the purpose of this catch can ?

Vetteman Jack

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.

drtyTshrt

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

Mr.Bill

I have had my catch can for some 5 years and have never seen anything like, In my opinion it is not normal.

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.

ALLEGRO

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

Obviously there is moisture entering somewhere.

Mr.Bill

Same here.

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.

What he said... Although I typically see this in my oil separator Mostly oil in my catch can....

drtyTshrt

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.

TXGS507

I check mine every 6 months or so.... However, my car is built and only gets driven to race or spirited weekend driving w my local Corvette club.... My set up....

drtyTshrt

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.

Seems to be I have it connected incorrectly.
