Engine Oil in coolant

[Mrg2783]

I have a supercharged 92 GT. Looks like blue bits from the felpro gasket are on the radiator cap. I have oil in the radiator and reservoir. I read online it can also be a cracked block. Just wanted to confirm before I tear it down, can a bad head gasket cause oil in the coolant but no coolant in the oil?

I changed the oil and it was black as night. No milky coloring.

If it’s a head gasket I’m happy lol

Cracked block I’m sad

The best way is to tear it down. You need the heads off anyway. Although they usually split under the lower intake. They do make a tool you can plug into your radiator, it reads carbon dioxide in the coolant. ( It reads something not sure what really) but also a compression check would tell you a lot to. I hope it's just a head gasket. Go copper.

Thank you! Yeah I tore down. I’m gonna do a leak down test this week. What copper gaskets do you recommend?
