Bone dry? Weird. How many miles?

Yeah it is dry. I'm at 18k right now. I was expecting some oil at least.

Here is a video. Hard to see but it is a $25 usb cam. You can see the dip stick in the video to the left. Nothing is on it when i pull it out either.

What is your normal driving day like, wasinger? Feathering the pedal, stop-n-go, lots of boost time? Only a drop of waste here & there, for sure!

Would like to have Nighthawk do his IC also, he's got a hi-mileage SHO.

I only drive the car on the weekends which most likely allows the moisture to evaporate. But I expected an oily sludge if anything.

My driving habits are mixed. Some weeks I'll be doing lots of WOT data logs back to back and some weekends I'll just cruise around.

I poked the camera around the intake valves and they are dirty. More than I'd like them to be. I'll upload that video tonight. Maybe you guys can tell me if the build up is excessive.

Meth kit is next on the mod list for sure. Just wish I could use the max mpg snow kit.

Interesting, I wonder how much if any this buildup in the CAC is location dependant?

Here is the humidity average where I live. So it can be compared to others.

The relative humidity typically ranges from 37% (comfortable) to 88% (very humid) over the course of the year, rarely dropping below 18% (dry) and reaching as high as 100% (very humid).

The air is driest around July 8, at which time the relative humidity drops below 44% (comfortable) three days out of four; it is most humid around May 28, exceeding 82% (humid) three days out of four.

Great how to! Thanks for adding to the list of must do's.

Just checked mine (I'm at 70k) and there is a good amount in there, about as much is shown on my dip stick as the first post. I tried to such as much out as possible but I couldn't seem to get much more than maybe a teaspoon. If I stick my dipstick down there, it still shows more. I'll be taking the front bumper off soon to remove the grille, and when I do I'll take a look at maybe putting a valve in the bottom of the CAC to be able to drain it easier. I will also be looking into getting an oil separator, thinking about a JLT for now.

Rich mentioned that you could jack up the front driver side so the crud flows over to the passenger side. Should be able to drain out significantly more that way.

I had mine performed at the dealer with a compressor suction gun which pretty much sucked it up but the ocd in me purchased a 3' drain opener and securly attached a microfiber cloth to it,probably help with anything left behind.Z

Nice, Z!

Bringing this thread back! Just checked mine and there's close to a 1/4" on the dipstick. More than i'd like to see for sure.

^ Wondering if anyone has done a drainplug/petcock in the CAC? How difficult do you guys think that would be? Obviously it would have to have a good seal but the idea of just opening a valve and sucking the fluid out the bottom every 10k or so is pretty appealing.
Also,don't see why a cheap tool like this wouldn't work to drain it from the top. Just drop the hose into the CAC opening and spray away

The CAC is NOT an oil catch can that comes with a drain valve and would advise to Only Use a suction type compressor air gun on TOP to suck out any trapped oil inside the CAC as seen on my video and definitely a great idea on Top. Z

Well obviously being a catch can is not it's purpose! lol. but what would be the harm in installing a drain valve in the bottom to easily remove oil buildup when needed?
