Good evening,

When you have this situation, the head gaskets are the most failure. This is a major undertaking even for a shop.

As far as the oil, coolant in the oil damages the main and rod bearings. This issue could well turn out to be an overhaul of the motor.

If you were to have a shop do the repair of the motor, you would be looking at about $3,000.00 to $4,000.00

Replacing the engine with a used engine would be around $2,000.00 to $3,000.00. I would consider this.

Get this confirmed by a shop before making a decision on what route to take.
