94 integra burning oil + white smoke

well you see how well of a lubricant water is and let us all know. first its like this. i say it was ran hot blowed a head gasket maybe warped the head drenched a couple of plugs so the couldnt fire and instead of calling a tow truck they drove it the rest of the way home therefore the water and unspent fuel that was getting by the piston at that time prematurely cut out the cylinder walls or caught by too much friction and broke some rings. then when they tried to fix it it was too late then changed the oil bandaged it up and then sold it to him this way,and its no different when you get water in your oil and it cuts the bearing then you spin one.it just happens. some times when a car burn exessivly rich your oil smells like gas because it runs down by the rings and into the oil pan and those motors wear alot quicker.

Sure, water is not the lubricant of choice when it comes to engines... but the cylinder walls are lubricated by an oil spray from the top of the connecting rods, not by fuel and combustion gasses from the top of the cylinder and combustion chamber. I highly doubt that in the operation of the engine significant amounts of coolant would be contacting the piston rings and cylinder walls (which are already coated in a very thin layer of oil). As we all know, oil and water don't mix, so the coolant won't be able to make contact with the cylinder walls.

Even if gasoline were being taken into the cylinder and not burned, as you proposed, I don't understand how that would affect the piston rings. The high ambient temperature would keep it vaporized, and it would simply by be passed without burning. Remember, the cylinder and piston rings are lubricated by oil from underneath the piston. I'm sure carbon and soot would make an even worse lubricant than coolant... but even though all engines have this, a well maintained engine should not suffer worn piston rings because of it.

A more likely explanation would be this.
The car already had worn piston rings from poor maintenance and normal daily driving. The smoke in the exhaust under acceleration has already been present. The car overheated and trashed the head gasket. Now the car burns coolant and oil. The owner no longer wanted it, so he sold it.

lol. well everyone has seen thier share of somthing diffrent but check this out below.

oil and water dont mix right! but if you put oil and water in a container and when it seperates the water is heavier than the oil and it always stays against the bottom side or in fact just runs of the water because it cant mix as oil also repels water. but in fact it can mix for a short time or the oil wouldnt look milky after it runs a while, then it reseperates after it setsthen when you drain the oil out comes the water then oil. so if the oil sets atop the water be cause water is heavier the oil couldnt lubricate the cylinder if it cant get to right?

So you're telling me that if I had a cylinder with a thin layer of oil on it and I sprayed water on it, the oil would wash off? If that were the case, we wouldn't need detergents and degreasers to clean our stuff. It's a vertical surface, so how does the weight of the water take the oil away?

The cylinder, piston and rings are lubricated mostly from underneath on the piston's down stroke, like I said earlier. There is some oil that gets by the rings and stays on the cylinder walls. This accounts for some of the engine's oil burning.

There are popular and legit methods of cleaning the cylinder by sucking in water through a vacuum hose in the intake manifold- up to a couple gallons. People who do this report only positive results.

oil rises on top of slick roads when it first rains, hence the first 20 mins of rainfall is the slickest the roads will be. but inside a motor i have no idea. lol
