2005 Mazda6 Auto - Oil in water - jammods

Hi, I have oil coming from the overflow pip of my radiator header tank. No water present in the oil though.

Does this suggest a blown head gasket - hope not!

Car hasnt overheated or cut out, but oily water has leaked all over engine bay.

Thanks in advance for any advice from the forum

Sounds very much the head gasket I am afraid. The only other possibility is a leaky oil to water cooler if it has one. Its a popular misconception that a failed head gasket causes overheating, what does cause it is if the leak is bad enough to pressurise the system and blow most of the water out.

Could be the turbo if it has one
