SOURCE: Nissan Maxima 1996 Engine oil turns milky white

Sounds like you may have a blown head gasket or a cracked head. There are test that can be done to check this the easiest and cheapest method I use is drope a few dropes of oil from your engine on something hot like the exhaust if it boils there is good indication there is coolant in your oil as the flash point of coolant is a lower temperature than oil

SOURCE: My 1996 Nissan Maxima has a milky colour engine oil & white smoke from the exhaust.

Check to make sure your gasket is not bad or the head could be damaged

Blowing white smoke

If you have overheated your car recently, then you possibly have a blown head gasket. Take off your oil fill cap (with engine off) and inspect to see if there is a milky substance underneath the cap. If so, bad news- head gasket. You can also check the oil dipstick for the same substance to verify bad head gasket, but usually it has to be pretty bad (gasket) or driven for a while before exhibiting any signs. The oil fill cap is a pretty good indicator. With the car cool, you can open the radiator cap and look and smell for anything other than coolant (fuel smell or oil slick). If so, probable head gasket.

I have 2002 GMC Envoy. Didn't over heat but when you turn it on it blows out white smoke and when you accelerate it blows out even more. I pulled over when this happened my gauges showed all was fine and...

White means coolant in the cylinder. With high mileage, the head can crack without over heating. Check the oil filler cap for a milky brown substance to prove there's coolant and oil mixing.

I have a 2000 ford contour.It's over heating and I got white smoke coming out of the exhaust. What is the problem? Thanks

Sounds like your head gasket is leaking coolant into one or more of the combustion chambers, do you have any water in the oil pan?(does the oil look milky? Or does the oil filler cap have a milky residue along with the overheating and white smoke you have, these are all tell tale sighn of head gasket failure.
Thanks, Frank

There is white smoke coming from the exhaust shooting out a watery substance. the white smoke gets worse as i drive it. there is no water in the oil or milky sludge build up and dont need to add water.

This acts and sounds suspiciously like a blown head gasket. You can't fix it if it is. I suggest you check your oil for water (pull the dip stick, is the oil milky white?). Get your car to your mechanic as soon as you reasonably can before you cause much more damage if this is a blown head gasket.

Alot of white smoke coming out of exhaust

If you are also losing coolant it is likely a blown exhaust gasket. The white smoke is a result of coolant leaking through the exhaust gasket and and being forced out your tailpipe. You can check to see if the head gasket is blown by removing your oil fill cap and checking the oil for a milky brown color. I hope this was helpful.

What causes the white milky subtance under oil cap. How do you prevent it?

The milky white substance is water mixing with oil. Oil normally mixes with water in your engine from a blown head gasket, but if your not having any problems with your car I have seen where a little water gets under the oil cap from washing the engine down. Hope this helps.

2005 Acura TL Turns over - won't start - grey smoke coming out of exhaust when engine turns over

Check for water in your oil. The oil will look like a milky substance kinda white in color. If this is what you see I recommend you take it to a dealership or a certified mechanic and have your head gasket replaced.

White smoke out the exhaust

You will need to check head gasket. Please check the oil for coolant (milky deposition or presipitation). Also check if you loosing coolant and if coolant has oil in it.
Please kindly let me know if you need more info
Good Luck

Lexus ES300 White smoke out the exhaust no milky substance in oil

It could be the intake gaskets or even still the head gasket. How about the coolant ? Did you refill with same type coolant ? Have you noticed if it's thick and gooey ? mixing coolants will sometimes produce a thick gooey coolant that clogs up the cooling system. If the car ran hot it could also be a cracked head or block. Warped heads also. Somehow the coolant seems to be getting into the cylinder(s).
