Is it cheaper to buy a used engine than to repair a head gasket?
In most instances. Get some quotes. The labor can be quite high to replace a head gasket.
True ... your looking at a 21 year old car whose resale is probably close to the cost of the repair. Unless the car is in otherwise good condition I would evaluate selling it as-is or going with the engine
I'd move on. As Tom said the vehicle is 21 years old. Whether you do the head gasket or replace the engine many many things such as wiring harnesses, vacuum hoses, sensors, etc. must be moved, unplugged, and disconnected. Then moved, plugged back in, and reconnected. Most of which haven't been disturbed since the car was built 21 years ago. Hoses and wiring get brittle and break. This creates bad connections and all sorts of trouble. Endless check engine light issues, poor engine performance, etc., etc., etc. I wouldn't bother with it. Use the money you'd spend on the head gasket or replacement engine for a down payment on something newer. You'll be better off in the long run. HTH. -Jim
