What could it be from. When i did an oil change about 2 weeks ago I noticed yellow and rust all on the inside of the oil filler neck. Im not using any coolant so it couldnt be blown coolant seal. I stuck a rag down as far as i could and still got globs of rust and watery yellow oil, anyone have any ideas?The only thing i can think of is when I sprayed my engine down and cleaned it, maybe the oil filler cap wasnt on tight and water leaked down into it.

 

How can you not be using any coolant????

 

well you know what I mean, not an excessive amount like If I blew a seal, lol smart ***

 

Oh right, well it could be the freeze out plug.
Search for a thread title; "Search for the freeze out plug begins today" Or something like that...

 

god i felt sorry for that guy..

 

I had the same problem in the spring. The car had been sitting for a while. After an oil change and driving around, it went away. My guess, condensation.

 

here to.

 

its just what i call OIL SNOT, i hope its not bad, both my cars got it, especially the t2. I hope its not a bad thing, my friends 7 also has a lil of it

 

Prayed to the coolant god's.
