Someone just gave me a 1986 GL Wagon, carb, 2W, 4Hi, 4Lo, 5speed.
Since it has coolant in the oil, I'm assuming a head gasket or cracked head.
I don't know the history of this problem, so whether it was badly overheated or not is unknown.
Where do I start with troubleshooting the exact problem? I've done minor repairs on an '83 Sub but nothing this serious.
Advice is appreciated.
