I recently purchased a 1995 Land Rover Discovery I with 130,xxx miles to tow my boat. However, the motor blew a head gasket and now I believe it has a cracked head. I took it into T & C Racing and was told the bottom end is making noise now too. They recommended swapping the motor out completely. The whole thing including labor is going to cost me $1,400. The new motor only has 35,000 original miles. I want to swap this motor and sell the SUV, since the boat is now for sale too. What do you guys think? Should I do the full swap or sell the vehicle as is?
