I went to check my oil today and noticed it was a lil low so i wanted to add a lil as i opened the oil cap i noticed there was soem white gunk in there then i took the whoel neck off and i saw there was more with gunk along with some green and yellow gunk when i emptied it out there was also clear water in the neck. Anyone know what happened?

There is probably coolant in your oil.

"Milkshake" is what we like to call that substance.

thats coolant mixed with your oil.. bad times will insue

PCV system isnt working as #2, condensation will get in there. Mine did that but it wasnt due to a coolant seal.

My gsl-se had that in the oil fill till I hook up the vac line that was blocked off on the neck. My motor only has 5K on it so I know it is not the coolant seal but mine was whiteish/clear not that green looking.


Tell ya what...... drain your coolant and change it to that orange color kind and see if it changes color. If it oes it is your coolant seal, if not you must have it blocked off. Are you using any coolant at all?

That is condensation, something in your emissions/PCV system either clogged, misrouted or not working. Do a search and you will find the answer here. I have that sometimes in my engines because I don't have the stupid pcv. I have been running my engines for years.

That or you're not warming it up before you turn it off.

i suppose it could be PVC, but it looks a little worse than that

The technical term for what causes that is emulsion. It happens when you get water (or some other liquid that doesn't mix with oil) in your oil. The detergents in the oil break down and attemp to mix the water with the oil so that you don't have a layer of water sitting on top of your oil in the pan that could get sucked into and destroy the engine. A little bit of this foam is fairly normal under the oil fill cap, due to moisture evaporation caused by the oil heating up when the engine is run, but a lot could mean something serious. It could be coolant leaking into your oil, which is bad and generally means your motor is on it's very last leg. It could be a loose vacuum line coming from the oil filler neck that somehow allowed water to enter the crankcase (rain, snow, washing your engine bay), or in very rare cases, if you live in a very humid area, it could be just the humidity, in which case you just need to change your oil. Don't count on the last one though. I would suggest changing your oil and checking to make sure you don't have any loose, missing, or cracked vacuum lines. After you change the oil keep a close eye on it. If the emulsion foam develops again within a week or two, you may have a problem. Also keep an eye on your coolant level and condition. If it looks like it is getting lower, or has little oil globules floating in it, or if it starts to turn brown, it may be an indication of impending motor falure.

Same here. I had that when I bought my car, car was sitting some time before me buying it.

Let's see... I see you have removed all of your "emissions" from that picture... I'd bet the "foamy emulsion" is due to an improperly ventilated crankcase... In fact, you can see it's not properly ventilated from that picture. If you're not losing coolant, you don't have much to worry about. My engine looks like this too... my old N/A with emissions intact did not do this.
