Re: engine oil dipstick shows water and rust mixed in...
Everyone always jumps to head gaskets. There are plenty of MINOR things that can be looked at first.
The Volvo 2.3, 2.4, 2.5 Inline 5 Cylinder dipstick tube is known to develop a large amount of condensationin winter months and stop and go driving. What you see on your dip stick is possibly just condensation. Take off your oil cap and look under the cap and inside the valve cover. Is there any thick foamy oatmeal like substance or noticeable amounts of water? If your oil was saturated with coolant, you would be able to see it up there too. Check your coolant for oil. Volvo coolant is typically brown to orange, however make sure there is no sludge. Start the car with the cap off and keep an eye out for alot of bubbles. A large amount of bubbles is a sign of a bad head gasket. A couple here and there is just air in your cooling system.
Coolant, Transmission fluid, and Oil have several places they can mix. If you have a turbocharged Volvo, the seals in the turbo can go bad and cause a mix of oil and coolant. Your transmission cooler is also in your radiator, and if it cracks your transmission fluid and coolant can mix. I believe turbo models have an oil cooler built into the radiator as well.
Overall if your car sounds fine, you dont see oatmeal, your not using coolant and oil in excessive amounts, dont have white smoke, and your turbo isnt whining you probably just have condensation in your dip stick. If you are overly concerned you can send a sample of your oil to a lab and have it tested for traces of coolant. Headgaskets rarely fail on Volvo's, even the old ones....I have seen many that have gone to replace them have not found a failed gasket and end up finding a bad transmission cooler or a bad turbo.

Re: engine oil dipstick shows water and rust mixed in...
Check you radiator fluid, see if there is any mixing in there too. If there is no indication of a Head Gasket problem, your Oil cooler could have a leak in it and that is a part of the radiator too.
You need to get that repaired soon and change the oil soon as possible too. Radiator fluid is corrosive to the Engine bearings.
Good luck and hope this helps.

Oil Life Monitor Resetting (KD, KE)
The engine oil life monitor will indicate when to change the engine oil and the engine oil filter - usually between 5 000 km (3,000 miles) and 12 500 km (7,500 miles) since the last oil change. Under severe conditions, the CHANGE OIL message may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 12 500 km (7,500 miles) or 12 months without an oil change.
The engine oil life monitor will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 miles) or sooner if the CHANGE ENGINE OIL message is displayed.
Reset the oil life monitor when the oil has been changed.
Press the INFORMATION SKIP button on the DIC control panel in order to display the OIL LIFE LEFT message.
Press and hold the RESET NO button until the display shows 100% ENGINE OIL LIFE.
have a compression test done on your engine to diagnose its state...if the cylinder head gasket has gone it will need replacing. You cannot fix it with sealnt.
The head gasket usually goes because of overheating at some prior time to the gasket going. The heat can cause the head to warp or crack in extreme circumstances. I n either case the head would have to be repaired if possible, adding sealant will not fix this.
The more you drive in this condition the more damage you are likely to incur
GM OIL LIFE SYSTEM - RESETTING The engine oil life monitor will indicate when to change the engine oil - usually between 5 000 km (3,000 miles) and 16 000 km (10,000 miles) since the last oil change. Under severe conditions, the "CHANGE OIL SOON" light may be displayed before 5 000 km (3,000 miles). The vehicle must not be driven more than 16 000 km (10,000 miles) or 12 months without an oil change.
Reset the oil life monitor when the oil has been changed, use the following procedure:
Turn the ignition key to the RUN position.
Fully push and release the accelerator pedal 3 times within 5 seconds.
If the Change Oil Soon light flashes, the system is resetting.
Start the vehicle.
The oil life will change to 100%.
If the Change Oil Soon light comes back on, the system has not reset. Repeat the procedure.
If its just condensation in the oil cap or dipstick, to some degree its normal. However if you have water in the oil and its very creamy in texture, its probably a head gasket leak, or cracked head. Its important to get it repaired soon, or total engine bearing failure will result.
The white creamy solution is oil mixed with water. Take out your dipstick and check for the same substance, if so, you have a blown head gasket. If not, it's just condensed water in your valve cover that mixes with the oil, witch isn't really a problem. Have a nice day!
seems to be water mixed with oil check engine oil remove dipstick and check how the oil condition if the oil same as soon as possible get in to experience technician to find how the water mixed with oil possibly by the oil cooler, is this information helped you? please vote me and leave a comment.
How did you determine that there is petrol in the mix? Oil and water mixing will show grey on the oil dipstick. Clear indication that you have a blown headgasket. Get the cylinder head off, have it resurfaced(at an engineering shop), new headgasket, reassemble, and Bob's your uncle you're under way again.
