The coolant will seep down through the cylinder wall into the oil pan.
thats quite psoosible , if the sputtering is at low speeds when the engin e is cold . A sure sign that you have a blown head gasket is when you loose coolant with no external signs of collant loss , you have coolant in the engine oil or vice versa . Any of those conditions warrant further investigation to determine the cause . usually a compression test and coolant leak test will show when you have a blown head gasket . elevated engine temp is also another common sign of a blown head gasket , get it checked out and repaired asap as you can quickly destroy an engine with a bad head gasket depending on how bad it is and how much coolant/lubricant are beign lost or mixed together.
Could have water (coolant) on it, or oil. If you are worried about a blown head gasket, be less concerned about spark plugs and check to see if coolant is in your crankcase, (motor oil) or vice versa.....oil in your radiator. It is possible for an engine to become hydrolocked, or seized, from coolant in a cylinder with both valves closed. But even if the engine is not seized pull spark plugs to see if there is coolant in cylinder. If there is, bad news. Do a compression check also............David
Most likely, your head gasket no longer seals properly. Coolant and oil normally circulate through separate channels in your engine. A faulty head gasket allows oil to pass into the coolant channels and vice versa. If your gasket is leaking, you will also have loss of compression in one or more cylinders and possibly white clouds of steam in your exhaust, from coolant getting into the cylinders.
A blown head gasket will pressurise the cooling system sometimes to the extent of blowing the radiator. A blocked radiator will cause a lack of coolant flow and overheating, which can cause head gasket failiure. Without inspecting the vehicle there is now way to tell which component failed first. Best wishes.
It may not look any different than normal. Symptoms of blown head gasket are: Loss of coolant with no apparent leak, engine overheating, white smoke from the exhaust especially at start up, overfull oil level, a white foamy substance on the underside of the oil fill cap, possible engine miss, & air bubbles escaping from the radiator with cap off. This is not an "improvement" on Clay's answer. I agree 100%, just more on the topic. It is obvious he knows what he is talking about. Could have water (coolant) on it, or oil.

Odds are you have blown a head gasket and the antifreeze and oil flow share the same gasket. As the gasket wears, the antifreeze mixes into the oil and vice versa! I suggest replacing your current antifreeze and do a full flush. Test it for a few days and test if you have oil again. A tell tell sign of a blown head gasket is black smoke (burning oil) or white smoke (burning antifreeze ) coming out the exhaust.
In short the cylinder head gasket can "blow" in various places giving a range of symptoms. If the gasket blows between the waterways and the outside of the engine water will seep out under pressure as the engine warms. You will note a loss of coolant. If the gasket blows between the oil and water ways you can find either water in the oil (usually seen as a white milky look to the oil on the dipstick) a rise in oil quantity as the water gets into the sump and a loss of water from the cooling system. As the cooling system runs under pressure it is likelier that you will see water in the oil than vice versa. That said there is sometimes a negative pressure in the cooling system as the engine cools which can draw oil back into the cooling system staining the coolant. If the gasket is blown between one of the combustion chambers and the cooling water ways you will experience high pressures building up in the cooling system. The raditor cap will lift and vent water into the overflow tank at relatively low coolant temperatures. Cracked or warped cylinder heads, cylinder liners or porous liners can give some of the above symptoms.
not very easily... Is their oil in your coolant or vise-versa? is your car smoking white? blue? Car overheating regularly? these are all signs of a bad head gasket but may be signs of a different problem....To check your head gasket you can do one of two things.1. do a leak down test2. pull the head off and visually inspect the gasket...those are really your only two options and both are time consuming

the coolant temperature sensor is faulty. It will need to be replaced
Are you loosing coolant? Is coolant getting mixed with oil or vice versa? Run engine to normal opeating temperature Remove dipstick and let a drop fall onto a hot engine part Oil will smoke coolant will sizzle Do a compression test 2 adjacient cylinders with low readings indicate a leaking head gasket
Combustion leak detection. The liquid changes color from blue to light green when Carbon Dioxide (in exhaust gas) is passed through it. It tests for leaks from the vehicle's head gasket(s) or cracked engine block into the cooling system. The head gasket is the culprit in most all cases. Also, if there is exhaust gas in the cooling system, usually there will be other indications of head gasket or block failure, such as white smoke from the exhaust (coolant vaporizing in the combustion process), oil in the coolant or vice versa (is known as the "chocolate shake" where the coolant or engine oil starts to look like milk chocolate from the two mixing), and/or bubbles in the coolant reservoir while the engine is running. The Combustion Leak Detector will tell you in no time.
