Is it coolant in the oil or oil in the cooling system?
Ask Your Own Mercedes Question
Customer reply replied 4 months ago
Definitely coolant in the oil. No oil in the coolant. BUT the coolant system gets very pressurized even though the car won't start.
The engine needs to be disassembled to check for cracks. My advice is to get a used motor. If coolant in oil bearings could be wiped out. I wonder how bad it overheated?

I was afraid you were going to say that, visual inspection. Could filling the coolant overflow tank full cause the head gasket to blow?

no it would not. usually its a deterioration of the gasket from coolant not being changed , 2 different types of coolant being mixed, overheat condition that warped the heads and block causing an seal integrity issue!!.

Thank you I will be happy to give you a five star rating.
I have one more follow up question.
Could doing an oil change with standard oil instead of the recommended synthetic cause this problem? The car was not driven with the standard oil.

either oil would not cause this issue at all!!
