Best Answer

A bad head gasket can do that or an engine oil cooler gone bad in the radiator. The year, make and model info would help.

If there is motor oil in the antifreeze reservoir there is a good chance there is also antifreeze in the motor oil. This condition is probably the result of a bad head gasket or a cracked head. Antifreeze mixing with motor oil is a recipe for disaster for the engine. Have a trusted mechanic diagnose the situation soon as possible to hopefully avoid even more costly repairs.

If it is motor oil in the anti freeze, then it is either a cracked head, cracked engine block, or a head gasket blown.

What does Brown milky oil in oil pan mean?

That means that there is engine coolant / antifreeze leaking into the engine and mixing with the engine oil. You must have an 1997---2000 modal V-8 or V-6 engine. It is very common for the intake gasket to leak coolant into the engine oil on those engines. Are you sure it did not freeze and crack the engine block ?? If you know that it had enough antifreeze in it not to freeze, Then you may get lucky and flush the engine oil and replace the oil filter several times AFTER you replace the intake gasket. OIL and ANTIFREEZE don't mix well and the antifreeze will destroy the engine BEARINGS.

What happens if you put antifreeze in where the oil go?

If you start and warm up your engine: 1) The oil gets very foamy and mucky, and does not circulate through the engine properly. 2) The water in the antifreeze can heat up until it turns to steam, which expands with great force, and breaks some part of the engine. It's best to have the oil changed. That will empty the engine of the oil and antifreeze mix.

What happens if you accidentally pour antifreeze where your oil goes?

First DON'T START THE ENGINE If you start the engine the antifreeze will be in the oil filter also Drain the oil out of the oil pan Take some new oil and pour it into the engine a few times and just let it drain out of the engine oil pan Replace the engine oil pan drain plug and then put the proper type of engine oil in ( less the amount the engine oil filter holds ) If you haven't started the engine you should be okay
