A head gasket can fail such that oil gets into water but not the other way round. How much oil in rad? Foamy?

SOURCE: Water mixing with engine oil

5.7's had all kinds of problems with intake manifolds but it could also be a head gasket leaking. One way to check is to pull out your spark plugs and have a look at them. One of them will should be really white looking, that is the cylinder where the coolant is leaking into. A good rule of thumb (but not always true) is that if the coolant is leaking into one of the cylinders at the very front or very back of the engine, it is an intake leak. If the coolant is leaking in one of the middle cylinders, it is a head leak.
But the only way to know absolutly for sure is to pull the intake off and look for a break in the gasket, if you see that you know its the intake manifold. If you cant see any signs of leakage its probally a head problem. Another word of advice, there is an updated gasket from fellpro that lasts longer that the OEM gasket.

SOURCE: 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.

If you see no signs of burning oil ie blue smoke from exhaust, ticking from the engine, then most likely you have a valve cover gasket leak. The reason you wouldn't see the oil in the driveway is the oil is burning off on the exhaust manifold. Check around the valve cover gasket for seepage (usually around the bolts).

Replace the head gaskets. It would have passed the smog test, because oil and water are not getting in to the cylinders.

How could I really tell if my head gasket really blown step by step


check running temperature,check oil filler cap to see if there is a creamy residue on the bottom of the cap indicates oil/water mixing same check of radiator cap,finally check oil dipstick if this shows contaminated oil this is a positive indication of head gasket failure, the rad/oil cap check may only indicate condensation reaction. HOPE THIS HELPS

What causes 02 buick century that not running hot to show the guage hot and the fan running and temp light to show


1 How do you know it is not running hot? Engines run normally at close to 90 deg. C, that is, close to the boiling point of water. The pressure cap on the radiator ensures that the water does not steam off at this temperature.
2 If the engine is not running hot and the gauge shows that it does, the gauge is faulty, probably the sender unit. I am not sure of the Buick, but some cars have two senders, one for the gauge on the dash and the other for the radiator fan. If your car has only one, the information from the sender is probably used by the ecu to switch on the fan, so if the sender is faulty you will get the symptoms you describe.

Hi my toyota corrolla verso radhaeters anti freeze water turns to cream at the top


I'd check the oil and see if you have any "cream" or discoloration of the oil as well.
Sounds like you may have oil mixing into the water...(usually looks like a chocolate milkshake.)
If this is the case, you may have a warped head (from getting too hot) or there might be an area where the water & oil jets are close and merely separated by a gasket. (i.e. Ford's 4.6 oil filter & upper water hose housing.)

Oil in water or water in oil either way isn't too good.

If after checking oil and its not "creamy" as well...maybe a good radiator flush would help.

Hope this helps...

Antifreeze looks almost black in color is thisnormal.


No this is not normal, Sounds like you may be getting a little oil mixed with the water flow. I would have this checked out because you may have a crack within the engine allowing oil to mix with your coolant system.
