Question about Cars & Trucks
I read that suppliers/bottlers were mixing in other vegetable oils to extend shelf life because pure olive oil gets rancid so fast. That makes those of us allergic to soy at high risk.
Try buying genuine brand oils sealed in bottles. Generic brands may be mixed but genuine brands would not do this as it would ruin their reputation

SOURCE: Oil engine oil mix with water
sounds like you have a problem with the head or head gasket.Pulled out the spark plugs and see if you have any showing signs of leakage from head/gasket.

SOURCE: water/oil mixing in 22r engine
yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.

You may have a intake manifold gasket that has gone bad or a cracked intake manifold which is causing the antifreeze to leak in to your crank case. keep an eye on your antifreeze level and have the problem repaired soon as you can, Antifreeze is corrosive to the engine's internal bearings and it's been known for bearing to fail as low as 2000 miles. Once the bearing fails your going to have to replace the engine, sorry for the bad news. This is common for the lack coolant service, after 150,000 miles or 5 years, the antifreeze will start to crystallize and restrict the coolant flow through out the engine. This will create hotter areas then others making gaskets and heads gaskets to fail. Keep me posted, be glad to help you get your Tahoe running 100% again soon.

The copper washers on the bottom of the injectors can give this fault if they are not renewed when the injectors are replaced .
If you have changed these allready and made sure you pulled them down exactly as the manual says in 3 stages then you may have a bad injector - see your Isuzu dealer .

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.
