This sounds like a blown cylinder had gasket. Although on some engines you will find core plugs below the rocker coverin the head.

You have coolant leaking into your crankcase.It could be a head gasket, cracked head, intake manifold gasket leak, or a cracked block. It seems Lumina's have always had head gasket problems. Probably the most likely cause. Check the spark plugs electrode areas. Are any white or gray and very clean? This indicate coolant is getting in there.

Two possibilities, one it could be leaking into the engine just through the leaking intake manifold gasket or yo could have a blown head gasket

Hi dear

First remove the cylinder head cover to see inside if there any water seal my leak if that is fine the second step is to check if you have oil cooler has problem if that is ok you want .
1- relece the water and oil from the engine
2-remove the cylinder head then check the cylinder head if there any craks specialy water holes.
i would advice you to resurvice cylinder head. also check the valve seats.
Use original parts you want new gasket.new oil filter .

2001 2.4L. Why is white smoke issuing from engine and exhaust?


White smoke is an indication of a bad head gasket and engine coolant getting into a cylinder.
Check:
- dipstick for coolant mixed with oil
- Radiator for coolant level.
If coolant on oil or coolant level low, time for some time consuming and costly repairs.

What make a 1999 dodge Durango leak water out of the over flow I took thermostat out


Water coming from the overflow bottle usually means excess pressure in the water system or a faulty pressure cap. The first can be a failing head gasket, the second is a cheap fix. Taking the thermostat out will have no effect on water loss but will have a big effect on cooling. If you remove the thermostat the water circulates too fast through the rad and overheating results. You need to find someone who can properly pressure test the cooling system to arrive at a suitable answer. Have you removed the dipstick? Has it a white sludge on it? Is the engine oil discoloured to brown with white traces? If so then a head gasket is likely. If you've run it for any time without the correct coolant mix then its likely internal corrosion has eaten the gasket. When all is fixed run the correct mix.

Oil in radiator , but there is no oil and water mixing in sump


I am assuming its motor oil and not transmission fluid, right ?
You can have a leaking intake gasket or head gasket and get oil in the coolant without getting coolant in the crankcase.
Same thing opposite. The bigger the leak, the better the chance of getting both at the same time.

Oil leak


Check your oil pan, did you run over something? That many quarts of oil has to be leaking from somewhere. Headgasket blown would likely show as water mixing with engine oil(no loss of water would likely remove likelihood of blown headgasket).

My 2003 Ford focus blew a head gasket a while back. I got fixed that, changed out the water pump, thermostate, water resevoir, and a few hoses. It started to overheat again, but the thermostate wasn&#


If you got a blown head gasket, water is getting mixed with your oil, pretty much ruining it, and your oil's viscosity will be affected, causing oil pressure to drop and your light turns on.

How do you know your car is overheating if it's not showing in your gauge?

When replacing blown gaskets there are a few things that is best to do, like sandblasting the heads, clean, scrape block and use proper torque an sequence, only removing old gasket and placing new ones won't fix the issue, those gaskets go through extreme conditions, expansion, temp changes, etc, they need to be put mindfully. I mention this because it seems you changed a lot and ended up with the original issue...

If your gasket is blown you need to fix that asap, then identify where is your coolant leak/blockage that causes alleged overheating, doing a coolant flush might help. Good luck.

The water isn't boiling, you apparently have a combustion leak into your cooling system. What you are seeing are compression bubbles. Possible cracked head or another head gasket. Sorry.

Audi a4 mixing water and oil together hissing,grey/brown foam


That is not true oil and water being mixed can come from many different places. Such as a bad radiator which would cause transmission oil to mix with the water also alot of audi's have a water cooled oil cooler which are a very common cause of oil being mixed with with water. These type of oil coolers are located under you oil filter. They have water lines hooked to them which cools the oil and when they go bad the water and oil will mix. So dont be convinced that its your head gaskets it could be but not as likely. You can pressure test your oil cooler to see if this is the problem just romove it an plug one off the inlet or with rubber plug which can be purchased at you local hardware store (I found mine at ace hardware in there specialty drawers where they have all there bolts) then attach a air hose to the other outlet pressureize the system and place it in a bucket of water. this should tell you if the oil cooler is bad but be careful not to ove3r pressureize the cooler this could damage it and caust it to leak. 15 to 30 psi should be plenty.

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.
