Oil getting into radiator/cooling system

I have had the head serviced and gaskets replaced etc. I thought this may solve the problem of oil into the cooling system. Has any one seen this problem before. 150kms of driving and tall the oil is pumped out of the sump and into the cooling system filling the expansion bottle. No water gets into the lubrication system, the oil remains clean all the time. Apart from that it is a mightyl little and goes really well.
Thanks for any help.

    update did run for 2 days with replacement block, radiator seemed fine, previous night changed tappet cover, thought pvc valve was causing rough idle, is idling better now but oil in radiator has increased substantially, theory is pressure in rocker area has increased now oil is forced between head bolt and head water jacket looks like head is faulty after all will try another, i do have a spear

    I have VB Bora 130ST PDI, withthe same problem, but I need to have it checked out, I spoke to some people and checked on the net, the common answer is the cooling unit, even VW would change the cooling unit first and if the problem still exist then they would change the head gasket. I hope its not a common problems with VW

    i have a VW and am having a similar problem. there is oil (not sure if trans or engine oil) in the coolant bottle. I took it to be repaired the head gaskit was replaced, all seals were replaced and the radiator was said to be fine. after the engine was rebuilt the coolant light came on again and upon checking there was oil back in the coolant bottle. The mechanic is now telling me he thinks the block is cracked and needs to be pressure tested or i need a new engine. However some else told me its probably just the oil cooler needs to be replaced. I have no idea wat the real problem is and am spending tons of $ trying to get this repaired...any suggestions?

    I have a diahatsu charade and have oil in the water system but the dip stick is free from water. Earlier this year i was looking at a charade from a registered dealer and that car had same problem nothing noticeable on test drive air con on and everything. No evidence of the oil until bonnet was popped and only because i saw oil residue on the bottle on the side of engine a mechnic from the dealership suggested that it could be a faulty thermostat amoung other things. I only realised i had the problem because of oil on the mudflap, the engine was not running rough or over heating no tell tale signs.

The only way for engine oil to get into the cooling system at such a high degree is if you have a cracked block. even a blown head gasket doesn't allow that much oil into the coolant system. if the block was cracked it would be the water jackets around the cylinder walls. even a cracked head would not allow for this to occure. now if you don't have engine oil in the coolant but transmission oil instead via the trans oil cooler this would mean that the radiator has a crack in the tanks along the side where the coils of the oil cooler runs through it,(this only applys to vehicles that have an integral trans oil cooler). another thing that could occure is that the heads are cracked and the coolant is mixing with the oil in the upper oil galleys in the heads and then getting pumped through the intake into the bypass. if this were to occure your vehicle probably would not start at all and even if it did I seriously doubt it would stay running. You stated that you just had the head gasket replaced. well if the heads them selves were warped or the block deck was warped and they were not planed then a new headgasket would not solve the problem to begin with. My suggestion is to take it back to the shop you had do it and have them do it again because i believe someone screwed up because you did not have this problem before so the mechanic did not do something right.

    Ronald, I'm going to disagree with you. I'm working on an engine right now that has an oil cooler in the water jacket. The oil cooler is about 9" long and 1.5" wide and 1.5" high. The oil cooler is made out of aluminum and it corroded. Oil pressure in th engine is higher than the cooling system and oil leaks into and with the coolant. I've had to replace the radiator, heater core, and all of the rubber hoses. Then try to flush the oil/coolant mixer out of the engine. Lot of work and time involve. but the engine runs still very strong and there was never any coolant in the oil system.

Well for oil to get into the water system, I would suspect the head gasket or the oil cooler (if you have one fitted it's located between the oil filter and engine). The fact the oil is migrating into the water would suggest a fairly high pressure source.

    I had the same problem, with a Charade (G102) CX 5-door hatchback (Australia) and eventually my mechanic found that the seals at the bottom of the cylinders were damaged. He took the engine apart and fixed the problems. $1400 later.

On my sons car it has a feed from the oil filter to the radiator. Perhaps the radiator is allowing the oil into the water. Suggest check/replace radiator.

How do I check for a blown head gasket on my 1990


Pretty much same answer as I gave for 87 Reliant see below. Shops have equipment to do cylinder leakage test. Do basic stuff below before doing last test ...cylinder leakage...which costs $$$.

Main point you are losing antifreeze/water. Check to see if you have water on the dipstick mixed in with oil. If so...probably a head gasket. If oil looks normal..... Before you do any test, tighten every hose connection. Check for loose connection into antifreeze reservoir. Sometimes there are small cracks on top which lets out pressure from cooling system. Look for leaks on water pump and radiator. Look at spot where you park the car...any liquid on floor? Not sure?..Put piece of cardboard under car to see if liquid is dripping from car. No leaks?...Start with a pressure test of the system. The pressure test is simply equipment that replace the radiator cap, a hand pump connected to it then air is pumped into cooling system. You watch the gauge to see if pressure is dropping. If pressure does not drop ..problem is most like a worn radiator pressure cap or stuck thermostat.. Do not buy the kind with button on cap to push down and release pressure. get original type and correct pressure. If overheating still, thermostat could be stuck, replace. Overheating of engine causes vapor lock, bubbles in fuel, which causes car to stall and kill. When cools off, fuel cools down and fuel will flow through fuel system again. Large amount of oil disappearing with overheating also sounds like head gasket or cracked head....Tighten up all bolts to gaskets, look for oil leaks on garage floor or driveway. If engine has developed a miss when running, pull plugs out and look for wet fouled plug. If antifreeze leaking into cylinder...plug tip will be whitish, if oil leaking into cylinder, grimey oil fouled. Do compression test on cylinder that is fouled and that will pinpoint if bad head gasket or cracked head. When doing compression test, radiator cap is removed and you listen to hear bubbles in radiator from the cylinder leaking into cooling system. 87 Reliant not worth pulling engine apart if head gasket or cracked head. Best oil treatment to reduce oil consumption is "Engine Restore" Used on my 58 Impala 348 tri power for 28 years. If I did not add it after oil changes it used oil and smoked....I swear by it for ANY engine after 100,000 miles.

Signs of a Blown Head Gasket
Note: You can only truly confirm your suspicion by actually seeing the gasket, although precursor signs are usually evident.

Input from Answers.com contributors:

If you see coolant leaking from the water pump, I would pressure-test it and pinpoint the leak and fix that first; oil seepage isn't necessarily abnormal.
Typical symptoms of a blown head gasket may include these: bubbles of air coming up into your radiator (remove cap before starting); a leaking radiator; milkshake-colored oil; overheating; rough running; coolant or oil running from head; spark plug(s) that have a green tint (if green coolant); white-colored or sweet-smelling exhaust.
White smoke from your tail pipe, or loosing coolant through your overflow. Take the cap off and rev the engine: if you see bubbles, or if it comes out, you'll know.
A blown head gasket will leave a dark smell in the radiator. And you will have high back pressure coming though your radiator cap.
Take your car to a radiator shop to have a detector installed: If the blue liquid inside a "bulb" turns yellow, you have a leak.
Beware that if you drive for too long and it overheats, a blown engine will be your outcome.
A blown head gasket can go out in different areas causing different symptoms. Do a compression test to give you some idea. Don't confuse low compression for a bad head gasket, though. A bad valve can lower compression. And a bad ring.
There are lots of clues you can look for. When in doubt and you have tried everything, have the head checked out by a well-established machine shop first, to see if the head was the problem. This way you're not wasting your time replacing the gasket.
My car once had a blown head gasket. I had a great deal of coolant loss. The engine lacked power and ran poorly. It had white smoke coming out the tail pipe. And it overheated very quickly. Also, it had water in the oil.
A quick way to check: Look at your spark plugs; if coolant squirts out, you definitely have a blown head gasket!
Low compression does not necessarily mean a blown head gasket, but it is a good indicator if there is a sharp drop in compression on one or two cylinders, with no drop in the others. Sometimes a blown head gasket will cause a whistling or wheezing sound, but not always. It will not always cause water to enter the oil - or oil to enter the water - but they are signs to look for. Overheating will almost always occur, due to the exhaust entering the coolant. Check your overflow bottle for exhaust smells. Watch for bubbles or overflow of coolant from the radiator while running the engine. Check for muddy gray-looking oil or bubbles on the dipstick.
Often (but not always), a blown head gasket will also cause deposit of water on a piece of cardboard held an inch from the tailpipe output while the engine is running (when this is happening, it is likely that the catalytic converter has been ruined and the muffler will corrode in short order as well). Sometimes drops of water will be seen dropping from the end of the tailpipe.
Another clue: Turn on the heater; often when the head gasket is blown an odor of antifreeze and synthetic rubber will emanate from the heater vents.
Many of the symptoms of a blown head gasket can be caused by some other problem in the cooling system, without the head gasket being damaged. Conversely, other problems with the cooling system can cause a blown head gasket and/or warped head. For example, a corroding radiator can send chunks of rust through the cooling system which take out the thermostat and water pump. If the thermostat is old, sticking and corroding, it can send those chunks through the system and take out the water pump or cause a blockage in the radiator, etc.
Radiator leaks can be the primary cause, or a result, of failures in other cooling system components.
Don't keep driving with the car overheated, especially if your engine has an aluminum head; you are likely to warp it. If it is warped beyond a certain tolerance, it cannot be planed and will have to be replaced when the head gasket is replaced.
One of the most common tell-tale signs is a milky-gray ring around your oil cap. When coolant enters the engine oil through a crack in the head or through a blown gasket, it evaporates and leaves a milky ring around the oil cap. Another easy way to tell is to check your oil dipstick. Change your oil and pull out the dipstick. Make sure that you take note of how far up the dipstick the oil is. Top off your cooling system and fill your cooling reservoir to the top. Screw radiator cap back on and start engine. Run engine for about 20-30 minutes or until it reaches normal operating temperature. Allow engine to cool (engine must cool completely to get accurate oil reading). Check oil dipstick again. If the oil has a watery appearance and has risen noticeably up the dipstick, then you probably have a blown head gasket or a warped head. Also, look for a sweet-smelling liquid coming out of your tailpipe. Any of the above symptoms could be the result of a blown head gasket.
The easiest way to tell is with a compression meter. This replaces the spark plug and lets you know what compression each cylinder is running at. If your compression is abnormally low, then you have a blown head gasket or a warped head. (Note: check the repair manual for appropriate compression of each cylinder.)
This can be detected in a variety of ways: One way is to note whether that part of the engine block is leaking fluid. This is difficult to determine since there are many other parts of the engine nearby that can also leak fluids, especially when a vehicle is parked in one place for more than a few hours. One of the best indications of a blown, or nearly blown, head gasket in most automobiles is when the cooling system appears to be malfunctioning. The cooling system's efficiency and performance can be directly affected by the quality of the head gasket.
If your radiator is getting low on water often, this is a sign. The water could be discharged through the tailpipe on your automobile. Another sign is if your car motor has a miss in the engine. The water could be going in on top of the cylinders. This will foul the plugs and cause it to miss.
There are a few simple indicators you can check for with the engine cold and not running: 1) contaminated oil - it will have a milky appearance from the water mixing in the oil 2) oil on the top of the coolant inside the radiator (if your vehicle has a remote header tank you may not get this); 3) Have someone crank (remove the coil lead or disable the electronic ignition) the engine on the starter with the radiator cap or coolant jacket bleed hose/bolt removed. If the coolant pulses up and down or blows bubbles, you could be in trouble. If you find any of these symptoms move on to removing the spark plugs (label the plugs and the leads as you remove them, so you can put them back in the same place) and again crank the engine on the starter. Depending on how badly your head or gasket is gone, you may get coolant or oil coming out of the plug holes. Inspection of the plugs will also reveal problems during combustion: if you have rusty flaky deposits on the plugs, you may be burning off water; and if you have a heavy carbon, you are burning oil. If you have any of the first 3 items listed (water in oil, oil in water, or pulsing coolant - but don't get any result from checking the plugs) change the oil and water as appropriate, then warm up the engine without the radiator cap on (or the bleeder hose/bolt) and watch for bubbles as the engine warms up. Put the cap back on the cooling system and take the vehicle for a short drive, or run the engine till the entire system is up to temperature and then check the oil for contamination. Having these symptoms is not always indicative of a blown head gasket; usually if the gasket is gone, there is going to be some warping of the head and or block of the engine.
Loss of engine coolant with no external leaks, a continuous stream of bubbles can be seen with the radiator cap off, black gummy and sometimes crusty stuff around the radiator


Several common signs of a blown head gasket:

Blue/white smoke coming out the tail pipe which indicates oil is burning
Dripping oil from the gasket itself
Carbon Monoxide or hydrocarbons in the cooling reservoir
Excessive coolant loss with no obvious source of leakage
Loss of power or a rough engine due to compression loss
Water mixing with oil
Oil mixing with water
Low compression in 2 or more adjacent cylinders
Remove dipstick and let a drop of fluid fall on hot part of engine - oil will smoke water will "sizzle"

Oil entering the cooling system


  • With a new radiator it sounds like a cracked head or a bad had gasket. The only place that oil can enter the coolant (other than a cooler line in the radiator) is from the two things I listed above. That's the only real place oil can pressurize into the coolant. A head gasket can leak antifreeze into the crankcase or oil into the coolant. Just depends on where the gasket (or block) fails.


  • You need to have a compression test to confirm this but if you replaced the radiator the head gasket ( in extreeme cases th block) is the the other reason for oil in the radiator.


  • Hope this helps.

I found some oil in the water of the rediator , and the mechanical change the gasket and still the same problem


You may be looking at OLD TRANSMISSION FLUID that has turned brown. This problem is normally associated with the Transmission Cooling tank leaking into the cooling system, there is not enough information in your write up to be 100 percent sure but I have had this same problem with a 328i

If it is OIL, then you are looking at a blown head gasket or a crack in the head or block. There are a few other ways to get oil in the system but I would start with troubleshooting the Radiator in a Tank and then see if there is air bubbles coming out of the Transmission fittings. This is going to be your first clue your radiator tank is leaking.

Good luck

Has anyone ever had water in the reservoir of an radiator mixed with oil in a 4 cyclinder 1998 saturn engine I had the head gasket changed and everything flushed but now I see water in the radiator.


Oil in the cooling system can come from two places. First is the head gasket or from a crack in the cylinder head. Could be residue from previous failure...If so, cleaning it out should get rid of it.
If your engine oil has any coolant in it or you are overheating or loosing coolant, though the job was just done, head could be cracked or warped. Second place oil can come from is the transmission cooler in the radiator. (automatic trans only) If it fails trans fluid (oil) will get into the cooling system. That oil is red in color and usually easily identified. Only way to fix that is to replace the radiator, but be sure it's that before buying one.

sorry dont run it. The cooling system is a sealed unit with no way for oil to get it. Problem the system is allowing oil from acrack in the block- head or metal area to the cooling system. Maybe a gasket that is alowing the transfer in the head area.

Getting oil in radiator --but no water in the oil--its NOT a blown head gasket or head -we allready checked that out -it's a datsun 1971 1600 cc engine with very low miles =truck runs great


What about the possibility of a crack in head gasket between oil passages and coolant passages. Oil pressure would be higher than cooling system pressure, thus oil would be more likely to enter cooling system, than coolant enter oil /lube system. Just a thought. Have you done a cooling system pressure test, just to see if any drop at all in pressure? Seeing how engine would not be running, oil pressure would be 0, and may allow coolant to seep through same path, only from cooling system, to oil. Is it a large amount that your getting?

Oil in water resovour vw 2002 passat


This is probably a head gasket problem and not an oil cooler problem.

The oil cooler is fairly easy to test.

Remove the cooler from the engine but do not disconnect cooling lines and then pressurize the cooling system. You can use a radiator test tool to put pressure on the cooling system and look for leaks. If it leaks, replace it.

You may also be able to bypass the oil cooler altogether if it leaks.

The head gasket is another story.

Get a 1/4" pipe to spark plug fitting and put a male air coupling fitting in it.

Then you can charge the cylinders with air from your compressor.

Make sure each cylinder that you test is at top dead center so that the valves are closed.

If air bubbles into your coolant, you found your problem.

If air leaks out your intake you have a bad intake valve

If air leaks out your exhaust you have a bad exhaust valve etc.


If you find this useful, please take the time to rate it.

OIL IN ANTIFREEZE


Everyone automatically assumes that oil and water mixing means a blown head gasket or cracked engine block. Of course common sense is usually not that common. Oil in coolant is a different problem than coolant in oil. The former is a low pressure leak, and could indicate only an intake manifold gasket. It could also be an early or small head gasket leak. Coolant in oil is usually a cracked block or torn head gasket, and has concomitant symptoms of white exhaust smoke and milky oil on dipstick. If you replace the head gasket and the problem persists, an intake gasket could have fixed the problem.
