I had a leaking hose next to the engine and i ran it with just water for a week(cause the antifreeze leaked out) till i could fix the hose. now the hose is fixed but the oil is milky and i was thinking of changing the oil but i heard i could also mix in diesel fuel with oil to help get all the water out then replacing the oil again?? what do you think??
just do a thing called engine oil flush, is like diesel, but is designed for its purpose. then you can change the oil after wards.
drain all the oil right away. put in fresh oil with maybe a pint of diesel and run it for a bit, then drain that and put fresh oil in it again.
this probably still wont help too much as you probably blew a headgasket or cracked a cylinder head. the latter is my bet because it probably ran hot because of the leaking coolant.
The antifreeze might not have leaked out, it may have leaked in.
You probably have a leaky intake manifold gasket, which is different and easier to replace than the head gasket.
But will is a lot of work, and will run you about $700.
The radiator fluid got sucked in past the old gasket due to the vaccuum in the cylinders, and the pressure in the radiator.
Change the oil immediately.
If it looks like mustard, well there you go.
You will need to change your oil every week or so, until you can get the intake manifold replaced.
If you dont, it can lead to damage, and also it will overheat and boil over. This is because the radiator fluid, or worse yet water ! will boil as the engine oil temperature reaches operating temp.
Dont fill it with water !, use straight radiator fluid.
Radiator fluid has a much higher boiling point than water, and wont corrode the engine like water will.
Forget the diesel fuel, it will thin your oil, and loose what little lubrication you have.
After you get it fixed, you can switch back to a 50/50 radiator fluid/water mix.
Start looking around for an honest mechanic.
if the oil is white then there is water in it and unless the water went in through the filler cap you have a head gasket problem .
change the oil and filter to get rid of the water in the engine if the problem persists you have head gasket or cracked head problem.
with the car running rough it sound like you cooked it when the water leaked out
Change the oil only, and change again later. Just keep check for “milky” deposits under the oil cap. please, DO NOT put in any kind of engine flushes, diesel fuel, or anything into the engine crankcase, ONLY motor oil. the water will do enough damage (if any) alone. Engine flushes only thins out motor oil and leaves the opportunity for serious damage because the lubricating properties are destroyed. I do not care if anyone says engine flushes are fine to use, they are not ! ! ! I wish i could show you some of the engines I have had to overhaul just from the use of engine flushes, and that was only sitting in a driveway with the engine running. A engine’s crankcase was only made for one thing, motor oil, and nothing else.
Don’t take chances with your engine. Change the oil and filter.
Your cylinder head gasket need to replace,.it is worn.
There is no other way but to replace it ASAP.
