Oil mixing with coolant

My car overheated. I had a thermostat and sensor installed. The idiot light now comes on and says that I am low on water. I do not have water on my dipstick but I do have water sludge on the bottom of the oil fill cap. I am trying to get an idea of what I will need and a cost estimate so that I do not get cheated. Tks.

Water in the oil.

I have a 1999 chevy malibu and my mechanic said that I have antifreeze in the motor oil. Can this be fixed? He said I might need a new motor

You probaly have a bad intake gasket, How long has this been going on? When that Dex-cool gets in the oil, its almost like sandpaper on your internal bearings, If you catch it in a reasonable amount of time, then repair of the leak is usaully ok, every one that owns a GM vehicle with the 3.1 or 3.4 has had to do intake gaskets on them, its only a matter of time, alot of times the coolant will get low, overheat, then your dealing with cracked heads or head gaskets, maybe your mechanic is thinking along those lines (head/ or head gaskets, or internal bearing damage from prolonged coolant in oil), then you could justfiy a new or used engine, but anyway first determine where the leak is coming from, usaully with a pressure tester you can put your ear to the oil fill tube on the valve cover and hear hissing internally if the intake gasket is bad and is leaking inside, but if the car has overheated(even once) have the coolant system tested for combustion gases, to find out if the head gaskets/heads are bad.

Hey Doc.

1998 Chevy Malibu 4 cyl Two Wheel Drive Automatic

what could be leaking out of my car that looks like water and oil mixed together?

I have a 1998 Chevy malibu and the coolant is leaking into the oil. Any coolant you add it just sucks it up. The past few months leading up to this it was hard starting and had a rough idle, I just assumed it was a vaccum leak and I would get to it when I had the chance. I believe it to be a blown head or intake man. Gasket. I am planning on repairing it myself and was wondering how I would go about locating the leak. Also it never overheated I only went a few blocks before figuring it out, what are the chances anything else has been harmed. Thank you any help or suggestions would be greatly appreciated!

My car was making a loud tapping sound it sounded like it came from the engine. I took it to repair shop and they said it was because water was leaking to the oil. Is this possible and how much would a repair like this cost.
Thank you

I live in the state of california cityof bakersfield the mechanic shop where my car is getting fixed said they would fix it for 300 to 400. Since I am your typical woman who does not know a thing about cars I had my dad take it for me. Is this a ok estimate
thank you
