Catch can dark granular/gooey residue--anyone ever seen this?

[hummus]

Hi all,

I found some residue in my dirty-side catch can and am very curious if anyone has any experience or theories on what this could be. As the title mentions, it seems granular, and somewhat sludge-like. What you see in the picture remained after I emptied the can, inverted for about 15 seconds or so. I haven't tested it with a magnet to see if it is ferrous, but I believe the can is aluminum anyhow.

This is on a 3.3 that has about 1700 miles, broken in per the manual by keeping the revs between 2000-4000 rpm for the first 600 miles with a few WOT episodes here and there during that time. The can was installed somewhere around mile 50. I first noticed this residue at around 1,000 miles and it seems to have been accumulating since then.

The condensate that poured out of the can was honey colored and maybe a bit less viscuous than oil, so perhaps a mix of oil, water, and fuel as expected. The oil was changed sometime between 600 and 700 miles, but I did not empty the can at that time.

Anyone have any ideas what this could be? Whatever it is, I sure am glad it didn't go through the manifold. Hopefully the can caught most if not all of this.

Temps cold in your area? I get the same as temps decrease. Condensation build up mixing with everything else.

looks like the can is getting hot and frying the oil it catches, is it near something hot?

Did what come out look like this?

Could be that substance is residual from the manufacture of the catch can and remained behind the mesh until it made its way through the mesh into the can. (?)

Looks delicious

Thanks for chiming in all!

Not cold at all here in South Florida. High 80s during the day, mid 70s at night

Not really near anything hot. Similar location to most Stinger-specific kits, in the empty space between the PCV line re-entry into the intake and the passenger quarter panel. The interesting thing is, when I tip it, the black mass separates a bit like a fine power.

The condensed blow-by didn't exactly look like that; it was more homogeneously honey-colored and hasn't separated. I did see that on my old cans with the first Stinger though.

This is very possible; the fittings are actually plastic and i did notice shavings early on, though those stopped quite a while ago--I check it pretty often.

Tall, Grande, or Venti?

My previous picture was what I get in winter or colder months when condensation build up due to the temperature variance. This one I have attached is during summer months. Pretty much a teaspoon of oil after a couple months.
