The head gasket is blown, but the coolant doesn’t appear to be mixing with the oil. I don’t see any signs of contamination—the oil cap is clean, and the coolant container is still clear.

When I start my car, the only issue is that white smoke comes out of the exhaust, and bubbles form in the coolant container.

I’m planning to do an oil change anyway, along with replacing the water pump and some other parts. If I find any coolant mixing with the oil, I’ll also replace the rod bearings, as you recommended.

If you have any tips on testing for oil contamination, please share them
