I have a 1995 dodge 1500 with the 5.9 360 gas engine i have oil in coolant reservoir but no coolant in oil also has no white smoke runs great but the oil is fresh oil in the reservoir any help would be great

Dense white smoke often indicates coolant in the exhaust. Check for water in the crankcase by inspecting oil on dipstick. Milky coloring indicates water. Check the coolant reservoir, or under radiator cap (wait until engine is cooled down!), for oil in cooling system. If you see evidence of either water in oil or oil in coolant, you may have a blown head gasket, or a cracked cylinder head or block.

cracked head or head gasket

Hi. If you see white smoke out the tailpipe, the engine is running rough and the coolant temp is getting higher and fluctuating. Your engine has a bad head gasket. There is no way the radiator cap can hold back that type of pressure. With the radiator cool and full. As the engine runs, you should witness coolant filling the over flow reservoir. Any questions please write back.

he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

Internal coolant leaks can and will cause

Usually a leaking head gasket if its not transmission fluid.
The gasket can leak oil into the coolant without leaking coolant into the cylinders.
You might also want to check and see if you have an engine oil cooler running thru the radiator.

I was going to say that white smoke wouldn't be oil but I see that you figured that out. Look for loose coolant hose clamps on or near the reservoir or possibly a small crack in the reservoir itself. As a general rule for gasoline engines: White smoke = coolant, Blue smoke = oil, Gray smoke = fuel, Black smoke = "Uh oh, that can't be good." :-)

The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?

Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.

Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.

If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.

What are you consuming, fluid wise, will direct where you go next.

Do you see white smoke from the exhaust? If so you may have a blown head gasket especially if this engine has overheated. Check the oil level and if it is overfull and looks like a cup of coffee with creme in it, you have coolant in the oil. Remove the oil cap, and if you see a foamy broth under the cap that is another sign of an internal coolant leak. If you see none of this then you have a leak somewhere. Fill the reservoir and radiator with coolant. Park the car over a clean driveway. Start the engine and then let it sit and run until you see where the leak is coming from.

There are only two things that cause smoke, one is oil,the other is coolant, coolant has a really nauseating smell, most likely the oil is your smoke, it is caused by worn valve guides and or leaking valve stem seals, if it doesn't use more than a quart every 1000 miles I would not worry about it, how many miles on the car?
