This is the second time I've had the same sort of contents.

Anyone have the same sort of contents?

What's this?

Where's it coming from?

Should I be worried?

Dude, you want to see a doctor ASAP!
oil and water vapour mix Willie, commonly known as mayonaise!
It does just look like really strong pee, lol.
Danny, just surprised about the volume of watery stuff. This is about 75-100ml of mostly water in less than 400 miles. So in 600-800 miles its about 150-200ml. This is with normal driving too.
I'll see how this changes on the track tomorrow night.
Where is the water coming from? Out of the oil?

The water is condensation from the breathers AFAIK. Mine looks very similar and fills up fairly quickly. I have run a drain hose with a tap fitted to the front bumper so can drain it through the grill.

I think this depends on the position of your catch can.

Mine is right at the front of the engine, in the cold airstream - so I get loads of watery liquid. I figure it's condensing out of the breather stream in the cold can.

I'll bet it's acidic. :D

My can is between the battery and the block so has a good supply of cold air too

You wouldn't want to drink it ;)

thats why catch cans are a good bit of kit, otherwise this stuff it flowed right back into the intake with all that nice clean air to be reburnt...

Also very handy if you blow your HG as they catch most of the crap as well :D

Any prizes for this??

Approx 150ml of 99% oil.
My can was emptied prior to leaving for Knockhill so this is pretty much what passed and was caught purely during the 1 hour track time, approx 50 laps of Knockhill.

I'm sold on these now, this might not be the best, most expensive or most pleasing to the eye, but I'm glad all this oil wasn't going into the intake.
I need to tidy up my PCV delete stuff but in the mean time its doing its job.
