So this morning i take my brother to drivers ed and its like 28* outside, i aint think to check the fluid levels... On the way there my heater core burst, the windows fog up then freeze. I make it nearly halfway home and the car cuts off...i pull over wait a second, get it cranked and it does this twice more, wiating and then starting works.

Later on i drain the oil its pretty black... I drop the oil filter in and around the oil filter are some like brownish swirls i would say. Would this be considerd mikly oil?

And i will guess that indeed my head gasket is blown ?

 

I would say no, when you pull the dipstick and it looks like you shook up some chocolate milk thats when you need to worry. But to be on the safe side rent a coolant pressure tester from autozone and test your system for leaks.

 

i would say no but im not possitive. i agree with cooter bout using the coolant pressure tester but if you drive it around for a while and see a whiteish milky foam on the oil fill cap (the side that faces the valves) then you are leaking most likely your head gasket but also possible intake manifold gaskets go alot also. although if you suspect a coolant leak into the oil i suggest not running the engine since it can seriously damage the engine most typically the bearings

 

I wouldn't freak out just yet either , short trips in cold weather can create condensation inside an engine resulting in some foam , If you ever tear into a little old lady grocery getters engine you'll see what I'm talking about .

 

i had a smart teacher at my school that told me that when running therre is more oil pressure than coolant pressure that would push oil into the coolant and that when the engine is off there is more pressure in the cooling system which would push coolant into the oil and when i had oil in my water jackets (long story) it made it all the way back into my coolant jug so look there too while you are at it will be foamy greyish brown color not orange residue clearly floating in there if you have any
