You are getting antifreeze in your oil. If you continue to run it the engine will be ruined. The oil pump will fail to pump foam. Sorry I can't tell you where the problem is. The first time I had this was with my 1953 Ford flathead v8. Luckily I happened to look at my oil pressure gauge just as it was dropping to zero. It needed a new head gasket.

SOURCE: how do i fix water mixed with my oil

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

your radiator oil cooler went bad and coolant got in your oil so replace the radiator the cooler is built in!

SOURCE: I changed the oil but my dip stick is showing way

Make sure you are not checking the oil with the car running first of all, second don't check the oil immediately after turning off the car let the engine stand for about ten minute allowing the oil to drain off the dip stick,

SOURCE: My 97 Chevy Camaro, Is overheating, The Thermostat

I hate to be the one to tell you but water (coolant) is in your engine oil. The more you run your engine the more you will hurt the engine. Stop running the engine. You have eather a blown head gasket or a cracked head or both. Your engine is full of scum and must be rebuilt or replaced. All of the scum (oil and water mixed) will never come out. It washes the lube off of all you engine parts and clogs up small oiling holes.

SOURCE: Have some white, milky looking substance on the dip stick

I'd be tempted to live with it depending on whether the vehicle is using coolant on the assumption that it is condensation causing the saponification of the oil. If the Lucas oil treatment caused the pressure to rise so dramatically I would suspect that some crud has come adrift and lodged in the pressure sender.
The chance that the cylinder head is cracked would be more rare than a leaking head gasket both of which could possibly be tested by a leakdown test of individual cylinders.
The water has to come from somewhere.
Does the soap go away when the engine is warmed up?

Testimonial: "Good point on the pressure issue, not using coolant. Dip stick had rust on it and so did the inside of the fill cap. Hot or cold white on the stick."

Why the water keep going down in the radiator when i fill it up?

It could be leaking into the cylinders. Check your oil to see if it looks milky

Foamie milky look on dip stick none in oil

You need to run a compression check on the cylinders and see if you have a head gasket leaking or an intake gasket leak. Milky look to the dipstick can only mean one thing and that is water in the oil and maybe the leak is just starting. It might be condensate but if it is it is not normal. If you don't find a problem I would check regular to make sure it is not getting worse.

Check list for answers to my Montero overheating...

Methods to trouble shoot
(1) check thermostat device. if thermostat is stuck - not working half the water used in cooling system is missing once engine heats up which can lead to over heating. (may need mechanic to check this)
(2) check radiator has water in it . if it is low there may be a leak in cooling system somewhere check rubber hose and radiator are not leaking.
(3) check fan belt is engaging fan in front of radiator
(4) if electric fan check if fan activates once car has heated up
(5) check oil level of engine on dip stick. If low oil add some oil and re check oil dip stick. DO NOT PUT whole oil pack in (don't laugh I know someone who did this and has to go to mechanic and get oil removed)
(6) if rubber hoses blow off connectors then you may have a broken head gasket seal. A pressure test of the radiator will confirm this.
(7) Possible water pump failure. Check by taking cap off radiator and run engine see if water is flowing in radiator and test if water is heating up in the radiator. Remember to put cap back on radiator when finishing test.
(8) check if bubbles or oil are in radiator water this could indicate a blown head gasket problem also.

I have a 1984 ford f150, I starts a runs until I come to a stop then It just shuts off...Whats wrong? I also have low oil pressure, and my dip stick for my oil looks kinda milky.

The problem you have is a cracked block. This allows water to get into your oil, and that causes the milky appearance. As you might imagine, this is not a good thing. You can try the block seal, but, there are no guarantees. Good luck. Oh, and by the way, it has nothing to do with the dip stick, just the water and oil failing to mix.

Gmc Sonoma 94 losing water no leaks not in oil or on floorboard. New water pump. New radiator cap.

your leak is likely in head leaking into the spark plug ignition area and burning of once vehicle is running check plugs for moisture before motor is hot, also can seal using blue rhino at auto zone I used on 6 vehicles and sealed all of them.

04 Dodge Ram V8 - #3 Miss fire - more than once! Had a tune-up, replace #3 plug & coil, swaped out coil & plug. Engine light still came on after running for a while. Checked radiator for oil,...

Hello crey60
Try checking the fuel injector on the #3 clyinder for dirt or damage. A faulty injector will cause a missfire code and trip the check engine light. Hope this is helpful.

I have oil leaking into my 1990 ford festivas radiator,what could be causing this?Is this a serious problem?

It could be the transmission oil leaking since the transmission fluid goes through the bottom of the radiator to cool off. You may need to replace the radiator. But if it's motor oil then there is a blown gasket on the motor or crack. Look at the motor oil on the dip stick and see if it looks normal or is milky looking indicating that there is also water in your motor. If it's just the radiator then it's not a serious as it is if the water is in the motor. Motor will be damaged with water in it.

My engine over heated. Is there a problem with the thermostat housing or unit

Usually when an engine overheats it is caused by:

1. In town driving and the fan switch on the radiator has failed and the cooling fan will NOT turn on. Check the fan by disconnecting the plug and applying power from the battery + and - to the 2 terminals/ The fan should run. If the fan runs only when you apply power from the battery and not while the car is running then the radiator fan switch is the prime suspect. It can be a fuse... or a relay but usually the problem is the switch itself. It screws directly into the radiator on the back side and will have 2 terminals on it.

2. The engine coolant thermostat located at the end of the top radiator hose is stuck closed. (Actually it is under the fitting the top hose attaches to on the manifold)

3. The impeller has falied inside the water pump housing. You can check to see if the impeller is working AFTER you have checked the thermostat. Fill the radiator with water all the way to within about 1/8 inch of the top of the radiator. On a WARM engine start the car and then rev the engine. You should see water flow inside the radiator.
No flow = bad water pump.

4. Engine Head gasket is leaking.
Pull the engine oil dip stick and see if the oil appears milky in color. If it does not look like oil and is milky then the engine head gasket has failed.
Also with the radiator cap off if you rev the engine and see quite a bit of water pushed out of the radiator then the engine head gasket has failed.

Those are all standard.. overheating problem checks. Hopefully the overheating incident has not caused other engine damage to your vehicle.

Thanks for using FixYa!
