Water and engine oil mixture in the oil sump. What can I do?

You are about to lose the whole engine. The issue is a head gasket that is bad. Could be a cracked head too.

hi there.
Water in the engine - Water can get into your oil sump in two ways: ... Water in the oil- Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is getting into the oil.
Water in engine oil
If you found water in oil car , this water engine car section is for you!
Water in car engine? Water should never be allowed to get into the oil in your engine or gearbox. Otherwise, it will result in significant foaming, dramatically reducing the product's lubrication properties.
Water in the engine - Water can get into your oil sump in two ways:

• Water in car - Water condensation in cold air or combustion gases: this phenomenon is extremely rare and only occurs at specific temperatures.
• Water in the oil - Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is getting into the oil.

Water in motor oil can cause serious damage to your engine - the oil will be denatured and no longer effectively cooled.
Contact your repair centre as soon as possible.

Your hole in the oil pan is from some damage caused when the vehicle hit something over rough terrain, I am assuming since it is a 4x4. The mixture of water and oil is because you have some leak whether it is a blown gasket or maybe some hole internally in the engine. Do you notice a brownish foam at the end of the oil dipstick if you check the oil, that is usually a sign that water is seeping into the oil parts of the engine.

Stalling at lo revs..
Try increasing throttle / idle speed on carb.
Set timing with timing light.

Oil puddles..
Use engine de-greaser to first clean entire engine
allow to dry, then
Check all seals and gaskets, esp
tappet cover gasket
head gasket
sump gasket
cam shaft o-ring seal
crank shaft o-ring seal

Water & overheating..
Top up radiator.
Idle engine.
Check for leaks around radiator, cracked hoses, water pump.

Could be engine and/or gaskets are blown.
Listen for wheezing / whistling sounds around gasket edges.

Have cooling pressure system donefirst to prove a gasket problem. Some engine head studs go into the water jacket and the head bvolts have a sealer around the threads to stop the coolant leaking into the sump.. Normally coolant in the sump oil is white or grey oil not yellow. If it is not over heating the problem may be else where.. Blown head gaskets are renouned for over heating in short time.

milky oil means water is mixing with it might be a gasket

hi could be the thermostat, take it out when engine is cold, put in a pan of hot water if it opens ok, if not bin and replace, if it opens then look for water leak.
or remove oil filler cap if you see a grey sludgy mixture,this is a mixtur of oil and water, it could be the head gasket, or a cracked block, have you run the vehicle without water, if so it could be the head or cracked block

Hi Koe, Most older cars do eventually develop oil leeks, typically/Hopefully its just the rocker-cover gasket that needs replacing. Check the colour and viscosity of the oil in your sump via the dip-stick, its good to change your oil and oil filter every 10,000 klm. Top your engine oil up to the full line on the Dip stick if its low, check your water level in the radiator, the water should be free of oil/dirt and put some antifreeze in, this will help protect your engine and keep the car running cooler, Top up your power steering fluid if it is low, This may fix all the immediate issues, after you replace all the fluids and filters, just run her at an stationary idle (no load on the engine) till she gets warm, take note if your fan is working, also check your belts!! You might find that its not even there! this would make the car over heat and the power steering pump wont work without it. all the best. Ian

It appears that you have a minor leak at where a hose attaches to an engine or radiator pipe. When the engine is hot, any small leak will evaporate quickly and therefore not be seen. As the coolant heats up it will expand into the overflow tank but once the engine is stopped the extra heat build up will force the coolant out the leaking joint. As the engine cools, the leak prevents the coolant from being sucked back from the overflow tank.

Check all hoses and clamps including heater hoses and those pesky little bypass hoses in the cooling system for a good tight fit and replace any hoses that have gone hard or have become soft and stretched. Those spring type hose clamps tend to be less effective in clamping as the hoses age. Worm drive ones are the best to use.

If unsure take vehicle to a cooling system specialist and have them do a pressure test and more thorough diagnosis.

If problem persists, then it could indicate a problem with the head gasket (Usually caused by allowing engine to become excessively overheated when cooling system has run dry) allowing very hot high pressure combustion gases into the engine water jacket, which super heats the coolant in the engine block, which then boils off, and is released via the cap or any leaks. If the head gasket is really bad it will leak water into the cylinders and into the oil in the sump. This is indicated by an emulsion of water and oil mix on the dipstick. You will also see white smoke (water vapour) from the exhaust.

hi, please check you oil level, ( on level ground). when the car is running place an old rag in front of you and take off the oil filler cap (be careful not to get near the fan, fan belt) if no oil comes out of the filler hole possible fault: oil pick-up pipe (in sump partial block), / oil filter in sump ( blocked), oil pump worn, oil relief valve (returning oil back into the sump), spring weak / broken. the (E C U) ENGINE CONTROL UNIT has many sensors that can stop the engine: but try cleaning the (EGR) ENGINE GAS RECIRCLING VALVE, this valve recycles gas back in to the engine, ( must be CLEANED with BRAKE FLUID) this is a VERY DIRTY job, as this gets block with carbon (EXHAUST PARTICULES). the E C U will detect all of these sensors: the (ECT), TOP OF ENGINE engine coolant temperature sensor rough tick over, (HO2), EXHAUST DOWN PIPE, heated oxygen sensor checks mixture of fuel, can adjust air / fuel, it tries to keep car going / may flood engine. (M A F) mass air flow, adjusts fuel / air retio this sensor can so much fuel to the engine it may flood it. flooded engine mean WET spark plugs. i would put it on dianostic machine to check these out before paying for extra sensors. gerry
