ok so there is oil in the radiator does that mean that i have a blown headgasket or what can it mean please help quick so i can figure it out

 

yeah. usually blown headgasket my friend. fix it before you cause permanent damage. and see what the oil looks like too.

 

Are you automatic or manual. If your an auto, I would suspect the cooler leaking into the radiator.

Any coolant in the oil? After the engine stops hot, there is no pressure in the oil orifice, but 13-15psi in the cooling system, that will transfer coolant into the oil.

Are you running a swap/engine with the factory donut oil cooler? (GSR/Type R's have these) Overtightening a filter can crush the separator plates in the cooler, resulting in a oil/coolant mix.

 

yeah that too. just check engine oil. if its a headgasket youll have somewhat milky oil.

 

Dude, did you just read what I posted...... wtf
