2001 z06 spitting oil
You might also put a catch can on it to see what accumulates.
It might take a while for the oil to be cleared if it is a bad PCV valve.
If the above does not help, check compression, but at 53 K it should not have any significant wear.





Here is a schematic of the two system. There is a rubber boot on the PCV and boot that connects the line to the valve. Those are well known to ROT and crack. Make sure yours is not cracked and its connected properly.
Remove the oil fill cap with the engine running. If the PCV is function properly, there should NOT be any outward flow of crankcase gasses from the oil fill. You normally get a little reverberation of air but little or no out flow.
The later years 2001-2003 PCV is improved but NOT perfect. A good quality catch can will HELP keep excess oil out of the intake manifold and out of the combustion chamber.
Pull off the air bridge and flop open the Throttle blade. Use a flashlight and see how much OIL is on the floor of the intake manifold!!!




CATCH CAN MAN !

The description below is very helpful and I appreciate it.
haven't dug into it any further but just started my car and nothing came out. Wonder if it is carbon?
I went through a fancy car wash recently and I believe they cleaned a bit in my b&b exhaust tips.... maybe some. Carbon broke loose and was tnixing with the water that I see on my cement.
My low oil light came on and I had recently topped it off. That's what had me concerned but no longer on. I'll check the level in a few minutes on the dip stick.
Sounds like Luke regardless if this is oil or not, I may as well get a catch can.
Sorry this his response is so sloppy . I am having a lot of issues typing on my phone and can't see what's being written

Looking closely the liquid appears to be clear.
