Bad oil cooler or blown head on 924S?

Here's where I'm at鈥rove the car and noticed it was hot. Checked and found the coolant level was usually low. Refilled all the way. Next day ran hot again, coolant level was down and there was oil in the reservoir. I checked the dip stick and it only had oil on it. However, there was some white frothy stuff in the oil filler tube. I fired it up once more to check the gauges. Oil pressure is fine, idol is okay, feels strong still. My hope is it's just the oil cooler. Anyone think it could be the heads?Bad oil cooler or blown head on 924S?

It sure sounds like a blown head gasket or cracked head or cracked block. The frothy oil is a dead giveaway that there is water in the oil. Coolant loss without any visible leaks is also a obvious sign. I would check a couple of things before I removed the head. First check the compression or better yet a leak-down test. Secondly a Combustion Gas Detection of the air coming out of the radiator will tell you if there is combustion gases escaping from the cylinder.
