If you open your filler tube you're likely to find a similar substance. I've been told that it is due to moisture.

If its the same stuff under the filler cap its from condensation building up and the motor running but not getting hot enough to burn it off. Have you been running it for short periods or let it sit a long time? You gotta get it fully heated and take it for a 10-15 minute rise to boil off any water in the crankcase from condensation.

Also when you first crack open your oil drain plug, is it oil immediatly, or some water/coolant first? If your leaking coolant into the oil youll get a lil coolant before the oil comes out as oil floats.

Pull the oil dipstick, if your oil looks like that then you've got coolant leakage.

mine and three other peoples catch cans that i have seen have looked just like that. the catch can is doing its job, catching all that nasty oil and moisture that would other wise be put back in your engine. looks like chocolate milk, just dont drink it

looks to be normal to me also. just be glad the catch can is catching all that and not putting it back into your engine...
