1996 Volvo Oil Issue

I have a 1996 Vovlo 850 with $200k miles. Recently when I went to check the oil I notice this white slimey stuff mixed in with the oil. There is quite a bit of this. I don't really drive the car much, just back and forth to work which is about a 20 mile round trip...... Any ideas on what would be causing this.

    Last oil change on our 1996 850 turbo (150K miles) the oil was black with no sludge however, the dip stick prior and after that shows the caramel colored sludge. No other fluids are escaping so the engine oil seems sound. I hear many responses such as PCV valve is bad or it does not get run long enough and condensation builds up. We replaced the oil cap however I'm thinking it may be the O-ring on the dip stick allowing condensation to enter and reside only on the stick base. Previous owner has had the engine flushed which makes me think he unloaded thinking the engine was going bad which has run great for over the last year. Does this Model experience ths problem often?

    Only other problem is how do we get the console off to replace the window switch which works intermitently?

Change the oil and filter.  I had this same thing happen; the sludge reminded me of chocolate mousse...  The mechanic who takes care of my car pointed out it had been a while since my last oil filter change.  Over time the filter gets clogged, and the engine basically whips up it's own oil - a la mousse.  A more expensive possibility is that the PCV valve is clogged and needs to be changed.  Again, in this instance the engine can't breathe properly, so it not only whips the oil up, but starts to shoot it out the dipstick hole, sort of like when you have to breath through your mouth when your nose gets clogged up because of a cold.  Didn't seem to injure the car, or freak out the mechanic.  Best of luck.

Occasional heavy smoke on tickover, but not using oil and oil clean.

HI do you now the color of the smoke
if engine emits white smoke its not burning the fuel
it could be water mixing with fuel = head gasket even tho you
dot have water in the oil
if engine emits black smoke - that's excessive fuel to air ration
check air filter & air inlet to see if clogged

if engine emits blue smoke - excessive oil consumption
cloud be valve seals

I have a 1996 Grand Cherokee and it just recently started making oil. I started running it about 3 weeks ago after it had been standing for most of the past 6-9 months. I dropped the oil (about 13 qts),...

The only liquid that can be getting into the crankcase and mixing with the oil is engine coolant. This is caused by a bad head gasket. Driving the truck as it is will cause serious engine damage. Have it looked at by a professional mechanic before driving it again.

I recently had my oil changed and they informed me of a sludgy like stuff on my dipstcik. They indicated that it was water in my oil and suggested I get into have it checked quickly>

If it was white then you have oil mixing with the oil if it was sludge kind of milky then yes you need to have it checked, you could have a bad intake manifold gasket or a head gasket going bad. If you blow the head gasket it can cost you a lot of money to replace the damaged parts. Replacing the head gasket before it blows will save you from having to buy a new engine.

Hi my hyundai excel 3 1996 white smoke everytime its idolling. not a black smoke. once its driving there's no white smoke, only when it stop or taking off.

Check your engine oil cap and see if the inside of it has yellowish gooey & slimey build up in it. If so you coolant is leaking in to your engine oil

Engine oil dipstick shows water and rust mixed in with oil

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.

Wrong Transmission oil

you dont need a complete oil change.
the other oil will also lubricate, so the oil you have put on, is as good as the oil who was there before
