There is oil in my radiator. what in the world do i do? How did it get there?

The car runs good and doesn't over heat.There is oil in my radiator. what in the world do i do? How did it get there?
you might be lucky and just need a head gasket..


worse case is your block or heads are crackedThere is oil in my radiator. what in the world do i do? How did it get there?
the only connection between coolant and oil is the head gasket. when you car is cool open the radiator cap. start your engine. rev it up. if water shoots straight in the air, your head gasket is blown. if not, drain your coolant and add new antifreeze and thank god that you dont have a blown head gasket.
do you mean on or in?


my guess would be a cracked water jacket in the block is letting blow-by gases/oil into the coolant..or you might have a bad head gasket...keep a very close eye on it severe engine damage is possible
head gasket or cracked block and or head. the pressure loss is from a lubrication passage into a cooling system passage. the fun part is finding it.
Your head gasket is going.


It needs to be replaced before things get worse. give it time before water get in the oil and it will cause more damage.


This is the metal gasket between the head and the engine.
It's not oil it's trainy fluid and you have a busted cooling line. unless you have a oil cooler it could be the line is cracked. replace the radiator
Sounds like to me you have a blown head gasket.
