Check the oil on the dipstick, if it is milky it is definately a head gasket. Also with the engine cold, open the coolant tank and fill to the brim. If you have a blown head gasket you will note quite a bit of air bubbling out, alternatively have it tested for exhaust gas in the cooling system, some service centers will be able to do this for you for free.

Oil in coolant problems on my 2001 cadillac catera?


Sounds like the head-gasket blew and allowed oil into the coolant and coolant into the oil. Unfortunately, it's time for a tear-down and rebuild of the engine.

If you see bubbles in your overflow tank, it is either overheating or (more probably) it has a blown head gasket. How long after engine cold start do the bubbles show?
A compression test could tell you more about the head gasket condition. You can also have the coolant tested against CO2 contamination.
Sometimes you can see oil on the surface of the coolant in the overflow tank when the head gasket is blown (check this with cold engine).

Why do I have oil in my 1997 honda civic coolant reservoir tank.


A few things could have happen,
1 you overheated and blew the head gasket and now the oil in mixing with the anti-freeze,
OR due to high Mileage the head gasket has just failed and is leaking into the anti-freeze journals inside the engine.,

Did you check the oil to make sure it's not a white'ish sludge on the inside of the cap, you might be mixing both back and forth..

1999 Cadillac STS OverHeating !!!


A blown head gasket or intake gasket does not always put coolant into the oil or produce smoke.. If the gasket blew between an oil vein and coolant vein then there is a possibility that your actually pushing the oil into the coolant side.. When the car is cool... look at your antifreeze and see if it has the oil slick look to it.. That being said it could be a head gasket or it could be in the intake as well..

Coolant and oil leak


have a compression test done as the bubbles suggest a blown head gasket or cracks. That will account for the overheating. The oil leak may be from the head gasket or cracks.

Replaced thermostat on pontiac sunfire now there's smoke coming from coolant tank


Sounds like you have a leaking head gasket or damage to the engine from when it overheated.
A leaking head gasket can cause compression to leak into the cooling system and pull coolant into the cylinders which is burned out the exhaust. It does not have to leak into the oil.
A shop would check for exhaust gas in the cooling system and run a compression test on the cylinders.

Overheating coolant boiling out into reserve tank


you have a blown head gasket.. doesn't have to have coolant in the oil for a blown head gasket... if hoses are rock hard when running then you have exhaust leaking into the coolant via a blown head gasket...

Excessive overheating!!!,water within oil.? Was told buy friend needed water pump.? Yet now told it may be the head gasket, or manifold gasket? To drive i constantly fill the antifreeze tank with water yet...


Sounds like a head gasket to me. If the oil is milky than the only way coolant can get into the oil is through the head gasket. Since there is also a lot of whit smoke out the exhaust coolant is getting into the combustion chamber and then getting pushed out the exhaust. Your best option might be to find a low mileage used engine. Heads gaskets can get very expensive!

Oil in over coolant tank


If there is oil inside the coolant liquid that is the head gasket.

Check first if oil can leak into the coolant tank from the cap.

Usually when you get oil into the coolant liquid you have an head gasket problem, do a compression test, or buy the home tester below.
