Hi Joseph,

That white fluid is emulsified oil and water. Coolant is getting mixed with the oil and the engine whips it into a sort of milkshake.

The head gasket probably failed along on or more of the cylinders. This would explain both the oil/water and the rough running. Have you noticed a loss of power?

I'd run a compression test to confirm it. But it sounds like you need to replace the head gasket.

Sorry about the bad news,

Mike

Dude, I have a XJ6 also, and it sounds like your head gasket has bought the farm. That milky fluid is water and oil mixed. DO NOT KEEP DRIVING THIS CAR WITHOUT GETTING IT FIXED IT WILL DESTROY THE BEARINGS IN THE ENGINE. The head gasket job is really not that terrible. It takes our techs around 6 hours to do the job. It will take you all weekend if your not used to heavy repairs. Be sure to get new gasket kit, head bolts, and change your oil 3 times in a row, letting it run 15 min in between changes to clean out the water in your block.

This is a sign that you have a blown head gasket or cracked head. Are you loosing coolant with no apparent leak? Do you see white smoke coming from the exhaust? If you do these are more signs of a head gasket problem. STOP driving the car immediately or serious engine damage will occur. This must be repaired now. A compression test will verify if this is the case.

I need to know how to tell if i have a blown head \head gasket


If you car is overheating often and white smoke come out the tail pipe when running, good chance it is. Easiest way it to check is the fluid in the radiator - look for oil floating on the top. If your cooling reservoir (off white container connected by a smaller black hose to the radiator) has fluid in it, check it or you can open the radiator cap (only when the engine is cool - hasn't been running - don't touch it until it's sat for a few hours if you used it) and use a turkey baster or similar to pull some fluid out. If you see some oil floating, it's most likely a head gasket.

Sorry, this may be a repost. I have a 1989 2.3 liter Ford Ranger i've been working on. I replaced the gaskets on the intake manifold and within two days a milky white substnce (oil & moisture)


The high idle is a vacuum leak from your work, as well
as the gasket issue is not resolved yet

Have to start over & check your work

I have a 1984 ford f150, I starts a runs until I come to a stop then It just shuts off...Whats wrong? I also have low oil pressure, and my dip stick for my oil looks kinda milky.


The problem you have is a cracked block. This allows water to get into your oil, and that causes the milky appearance. As you might imagine, this is not a good thing. You can try the block seal, but, there are no guarantees. Good luck. Oh, and by the way, it has nothing to do with the dip stick, just the water and oil failing to mix.

2000 durango milky substance in oil cap


milky in the oil cap is ok -- this is caused by condensation and oil mixing inside the oil cap and it is nothing to be worried about.
now if you look at the dip stick and you see a milky looking oil on it -- and if you do a oil change and notice it to be milky - then this is a sign that you may have a blown head gasket, and this you need to worry about.

Chevy s-10 pick up truck ,158154, 4cyl engine, wont start


Milky substance on your dip stick indicates contamination in your engine oil, most likely coolant and that is an indication of head gasket, or intake gasket gone bad and coolant leaking into your oil system. Note that coolant in your engine oil is bad, coolant will corrode the internal engine's bearing causing you to replace or overhaul the engine. The engine not starting is most likely the result of being blown and will need to be replaced.
Thank you for using Fixya and god luck

Smoke emitted from the engine area


If your oil is turning milky and smoke is coming from the engine check to see if your exhaust smoke is blowing white. If it is, you've got a blown head gasket. Hate to be the bearer of bad news, but good luck.

Engine oil moisture


Known issues or not,It sounds like the head gasket is blown,or it has a cracked head.If it was water it would be thick and light grey in color on the dip stick,But yellow indicates antifreeze leak that has not had time to mix with the oil.

My toyota has white blowby on oil cap is this a sign have a blown


It could just be some sort of condensation. I would clean the oil cap well and drive it for a few days. Then check it again. If its a coolant leak it will not go away. I would eliminate the easy stuff before you tear into it.
