What is this? (Picture)

[going4speed]

with the pcv open to atmosphere with no check ball like a pcv you are sucking in atmosphere when the car is off as the car cools off.

The BIG question though is that why would I not see any of this substance present on the dipstick, or when I open the oil cap and look inside the valve cover? This substance is ONLY present coming from the hose connected to my valve cover and only when the vehicle is off for a long period of time. For example. When I park the car, I looked 15 minutes after and didn't have a drop. After two hours I had a little, after 4 hours I had a bunch.

having the info on it coming DIRECTLY from the valve cover would have been helpful earlier

This build up is commonly found in short tripped vehicles even with good PCV systems. I would repair the PCV system and allow the vehicle to fully warm up before driving about once a week. My girlfriend drives 3/4 of a mile to work every day and this can be found in her 2010 Colbolt. Let the car run until fully warmed up once a week and this problem is gone.
Just my 2 cents

I only drive this car to and from work which is a 15 mile trip, so it always fully warms up. I am so confused.

I'd consider draining the oil out and try scrapeing the bottom of the oil pan through the drain hole with a q tip or screwdriver to see if you find any of that same sludge in the bottom of the pan as oil floats on water it may not show up on the dipstick

and , just because your head gasket was good last week dosen't mean it is still good this week
- especially if it's an old o-e one
they rot around the water passages and get punky given enough time - which is why I never use a mopar head gasket

[turbo_shelby]

I am going to drain the oil tonight. If I see any milky colors I am going to say a head gasket with probably a very minor leak. (because I have no noticeable smoke from exhaust or no noticeable low coolant)

I did some more research though and it appears I may have a valve cover baffle issue which would cause me to lose oil without burning it and without seeing puddles of oil after parking overnight.

Another guy did tell me that the sludge in the picture could be oil vapors cooling with humid air, which would cause the "muddy" substance.

why did you think it was a good idea to eliminate the pcv setup in the first place?? were you trying something? it just doesnt make sense is why i'm asking.

Good Question... The reason I took it off is because the area under and along the nipple coming off the valve cover was saturated in oil. I thought I had a valve cover gasket leak, but realized that when i took the PVC valve off that the rubber tee on the nipple was cracked (it fell to pieces when I removed it) I plugged the vacuum source and just ran a heater hose from the nipple to below the car. Even with a PVC valve, there was still a direct path from the valve cover to atmosphere because the PVC valve just sucked when the intake was in a vacuum and did nothing when in boost besides close and not allow pressure back into the crankcase, then the crankcase ventilated to atmosphere anyhow.

How many miles/minutes do you drive each day?

[turbo_shelby]

15 miles or 30 minutes each way to work and back.

[Lotashelbys]

I would do a compression test and coolant pressure test if you havent already and report back with the numbers and if the coolant tester loses pressure.

[Jakecs]

Ok. Was gonna say. If the car can't warm up properly its easy for oil/water mixture to build up. My car would always do it when I used to drive a short distance commute.
