Gas/OIL MIXTURE IN MY CATCH CAN!!!!!

[tbis]

I did an Oil Change with Mobil 1 full syn. dexos. about 1000 miles ago.
Did a check on my catch can. Since I installed the catch can the Oil has been a rich black color. Do my LOF changes frequently, It's tuned with the IPF, Has a CAI, Ported Throttle body and MRT V2.
Since this past Oil change i did install a Vitesse Throttle Controller. Normally run the Sport settings was wondering if that could be why the oil looks so filthy letting to much fuel into the system.
It Smells like Gas is mixed with my oil in the catch can.

I'd say it's from condensation. If you still have it you can send it for an oil analysis. http://www.blackstone-labs.com/

+1 for condensation. That's completely normal in the cooler months and there is usually a fuel smell to it regardless.

Get rid of that catch can.. It's useless... I have had cars 30 years old that ran great with regular oil changes..

Currently have a 28 year old Ford with 147K on it with no issues..Unless you are competitively racing your car regularly like an animal, you do not need one..

I do still have it was going to take it to the dealer and show them. Just freaked out when i saw that. Thank you for the responses. Thinking about getting a 2012-13 SS once they release the 16. Don't want any issues before then.

Worst advice Ive seen on the forum. Im not trying to be mean, but you have a V8 and Im guessing little to no knowledge of these engines(LFX). These are direct injected and the valves are not "cleaned" by gas like your car, blowby is way more excessive and condensation build up like seen above is a common thing, but instead of going into a can like this smart fella, it would instead be going right back into his manifold mmmm. Engines have changed since the hayday of v8s and leaded gasoline, especially these economic 6s.

That looks like coffee with milk.

The PCV was designed to work without a catch can. This is the kind of stuff the engine would normally get rid of through combustion by blowing it back through the intake.

Normal

This is what my truck looks like in winter then goes back to a black color

There's a reason why BMWs require intake removal and walnut blasting these days. It's because of Direct injection. Like you said, the valves don't get cleaned by fuel and oil from the PCV system gunks up on them hurting air flow and decreasing engine efficiency.

So, if anything needs a catch can it's the direct injected V6. The LS3 and L99 probably would be perfectly fine without one, especially with all the detergents in fuel these days. It certainly doesn't hurt anything though.

Id rather not risk it. Cost me around $100 for a piece of mind and I dont have milk in my intake manifold. I check every oil change, clean as a whistle. Yours?

Risk what?

At 12k my intake has no milk in it. Looks like an intake should.

Im not trying to give you a hard time. Its just that its time tested and proven on this forum to help keep our valves and intake manifolds clean(er). Ive been here for a only little over a year and I've seen it time and time again. Im at 52k miles to your 12k miles. Check it at 20, then 25. You'll be singing a different tune, but I hope Im wrong.

Btw my engine went before I had a catch can, and the valves and IM were horrible and the tech noted this to me. Related, probably not. But

interesting walnut blasting I've heard or that on industrial gas turbines also, plus rice both combustible residues I guess

catch cans the new tail light lol
I have one too! the colder climates have always cause the greasy deposits due to colder starts and condensing exhaust

exhaust. Most of the exhaust comes from chemical combinations of the fuel and oxygen. When a hydrogen-carbon-based fuel (like gasoline) burns, the exhaust includes water (hydrogen + oxygen) and carbon dioxide (carbon + oxygen). But the exhaust can also include chemical combinations from the oxidizer alone. If the gasoline is burned in air, which contains 21% oxygen and 78% nitrogen, the exhaust can also include nitrous oxides (NOX, nitrogen + oxygen
