Question about 1998 Ford Windstar

1 Answer

Coolant leaking into oil

The engine runs smooth and with power. I would have never known I had a problem except it would overheat and I would find a great deal of coolant missing, and the oil level high. When I took the oil fill cap off the valve cover and looked inside, I found that the oil was thick and grease like. What I don't know is the likely pathway the coolant is taking to get to the crank case. As I said at the start, the engine is running just fine, so I can't believe that it is a head gasket. We already had that problem in the past and the engine was rebuilt. The rebuilt engine has about 40k miles on it.

SOURCE: Fos the past five months unexplained coolant

Thick black oil generally does not indicate coolant in oil...that appears as coffee coloured residue with a milkshake thickness to it. But, I'd let the car stand overnight and then drain oil. coolant will stay at the bottom of the pan and exit first, so watch carefully.
Next, have a shop dye check for leaks...often small leaks are in the form of seepage that is light enough to evaporate on the hot engine before reaching the ground. Another test you can do is to let it sit overnight with the radiator cap off. Sometimes a water pump seal will only leak when not under pressure. (like when you try to empty a can of dog food...punch a hole in the bottom of the can and it will fall right out!) Also, check the rug inside the car...any dampness indicates a leaking heater core.
I hope at least one item here will help. Obviously if you are loosing coolant, it has to be going somewhere. PS: use a good grade of synthetic oil and it should not break down as quickly as what you are using (regardless of if contaminated or not)

SOURCE: Low coolant and oil smells like gas. No white/blue

let your car idle go back to the tail pipe if it seems to be steaming alot , and or smells like antifreeze then you have a head gasket problem or a gasket leak alowing in directly into your engine

SOURCE: Slow to rapid coolant rise after engine is shut off

Normal. This is called heat soak. When you stop the engine, its temperature rises since the coolant is no longer being circulated by the water pump through the radiator. The coolant then expands and goes higher in the overflow tank. As the engine cools, it retreats back into the engine. Proper level should be determined only when the engine is cool.

SOURCE: Their is a white milky

No, it does not mean you have a head gasket failure. Moisture can build up under the cap and when the moisture mixes with the light oil film, it will appear milky. If there is no evidence of coolant in the oil on the dipstick or evidence of coolant in the oil when it is drained, then there is no reason to believe that there is an internal gasket failure, unless of course, you are overheating or the engine is running a high temp.

What are the symptoms of a bad intake gasket on a 1999 buick century?


Coolant leaks,When the intake manifold gasket cracks or blows out, coolant will leak out of the intake manifold. You may see puddles underneath your car or notice smoke or steam coming off of the engine and exhaust from the coolant dripping onto it and then burning.Overheating, If the intake manifold gasket fails and allows coolant to leak out into the engine, your car will begin to overheat. If your car frequently runs low on coolant or begins to overheat, check the intake manifold gasket.Running poorly, When the intake manifold gasket falters, it affects the way the motor handles its emission gases. The change in pressure can affect the vacuum in the intake as well as how smoothly your car runs. Mainly, it will idle roughly and may hesitate, cough or sputter.

Gets hot and low power


1 If engine overheating has occurred the coolant level will naturally be low due to expansion of the coolant from the extreme heat of the engine. This heat expansion forces coolant out of the radiator and coolant reservoir. To test for an engine coolant leak move the car to a dry smooth surface and allow the engine to cool. Remove the radiator cap and carefully (do not spill) add water until full, then re-install cap. Start engine and allow to run for about three to five minutes (do not allow to overheat) while the engine is running inspect the ground below the engine, if an engine coolant leak is present observe the location of the coolant drops, this will help determine where to start looking for the coolant leak (shut the engine off before inspecting). If no coolant is observed two additional checks are needed for a complete test. With the engine off remove the engine oil fill cap and turn it over, if a milky oil condensation is present the engine may have a failed cylinder head or intake manifold gasket allowing coolant to leak internally. To inspect engine gaskets disassembly is required. Next, the car heater core must be inspected; the quickest way to check the heater core condition without removal the heater core is to inspect the passenger's side foot well compartment carpet for the presences of coolant. If coolant is present the heater core has failed and must be replaced or repaired. After necessary repairs have been made refill the cooling system with manufacturers recommended engine coolant and recheck operation.

Car overheated and lost all power. how do I get it to start?


ENGINE NOT GOING TO START IF GET TOO HOT FIRST THING I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP THEN ADD COOLANT UNTIL COOLANT LEVEL CORRECT THATS WHEN THERMOSTAT OPEN UP AND TOP HOSE HOT.CHECK FOR LEAKING RADIATOR HOSES CHECK TOP RADIATOR HOSE CHECK BOTTOM RADIATOR HOSE.CHECK FOR LEAKS AROUND THE RADIATOR LOOK DOWN BELOW COOLANTS FANS CHECK FOR LEAKS AT RADIATOR CORES OR LEAKS AT THE RADIATOR PLASTIC SIDE CONTAINERS. CHECK FOR LEAKS AT WATER PUMP WEEP HOLE AND CHECK FOR LEAKS AT THE HEATER HOSES AROUND ENGINE BLOCK TO THE HEATER CORE HOSES. THERE IS A REASON CAR OVERHEAT.IF CAR OVERHEAT WHILE DRIVING YOU HAVE FAULTY THERMOSTAT OR LEAKING OUT COOLANT OR BLOWN HEAD GASKET.IF ENGINE OVER HEAT WHILE SITTING DURING A LONG IDLING PERIOD.YOU COULD HAVE FAULTY COOLANT TEMPERATURE SENSOR OR FAULTY COOLING FAN FUSE OR RELAY.HOT WIRE COOLANT TO SEE IF IT RUNS IF NO REPLACE FAN MOTOR. IF YES FAN MOTOR COULD HAVE FAULTY WIRE OR PCM FAILURE. CHECK ENGINE CRANKCASE IF OIL LOOKS LIKE MILK SHAKE ENGINE HEAD GASKET LEAKING.

I have a 90 chev camaro rs since new, but since then this vehicules has the same problems, "getting hot" and hotter when getting older. I have change every detail at it and even a additional...


Inside your car's engine, thousands of controlled explosions called combustion events occur. These explosions are created by igniting a fuel / air mixture inside the engine. Spark plugs are used to ignite the fuel / air mixture contained in the cylinders. These explosions are converted into power through the engine while producing a large amount of heat. These high temperatures are controlled with the help of the cooling system. A cooling system consists of a water pump, cooling fan, thermostat, radiator hose, hose clamps, radiator, radiator cap and coolant. Engine coolant is used to transfer heat from the engine to the radiator by the cooling system. The radiator removes heat from the coolant by forcing air through the radiator cooling fins. Without coolant your engine will overheat and if left unattended severe engine damage will occur. Engine coolant colors can vary from green, orange, blue, clear and yellow each having their own unique protective and environmental properties. Coolant leaks are a common car problem that can lead to overheating; we have listed some of the most common causes below.(Always inspect engine cold to avoid personal injury) (note: coolant and antifreeze refer to the same product, in below freezing, coolant lowers the freeze point hence the name anti-freeze and in warm weather coolant help raise the boiling point, "coolant").
Troubleshooting Procedure
Step 1: Check Engine Coolant Level, Test For Leaks - Engine coolant is used to transfer heat from the engine to the radiator; if a coolant leak is present the engine will eventually overheat. Inspect the engine coolant level in the coolant reservoir tank; coolant level should be between the hot and cold marks. Always check the coolant level when the engine is cold, preferably over night. If the coolant level is not between the reservoir marks the cooling system may have a leak.

If engine overheating has occurred the coolant level will naturally be low due to expansion of the coolant from the extreme heat of the engine. This heat expansion forces coolant out of the radiator and coolant reservoir. To test for an engine coolant leak move the car to a dry smooth surface and allow the engine to cool. Remove the radiator cap and carefully (do not spill) add water until full, then re-install cap. Start engine and allow to run for about three to five minutes (do not allow to overheat) while the engine is running inspect the ground below the engine, if an engine coolant leak is present observe the location of the coolant drops, this will help determine where to start looking for the coolant leak (shut the engine off before inspecting).

If no coolant is observed two additional checks are needed for a complete test. With the engine off remove the engine oil fill cap and turn it over, if a milky oil condensation is present the engine may have a failed cylinder head or intake manifold gasket allowing coolant to leak internally. To inspect engine gaskets disassembly is required. Next, the car heater core must be inspected; the quickest way to check the heater core condition without removal the heater core is to inspect the passenger's side foot well compartment carpet for the presences of coolant. If coolant is present the heater core has failed and must be replaced or repaired. After necessary repairs have been made refill the cooling system with manufacturers recommended engine coolant and recheck operation.

White cloud of smoke through tailpipe


well I'd say that coolant is definitely leaking into the combustion chamber, albeit at a slow rate (for now). It could be anything from a blown head gasket to a cracked block or head. I'd get it to a shop as soon as possible and not drive it any more than need be until that point.
