Look for a similar car on Row52 dot com that has some crash damage. Check under the oil cap and make sure it doesn’t look like a chocolate milkshake. Pull the motor or hire someone in the yard for 100 bucks. You’ll be out of there for 250 bucks. You can likely find a mobile mechanic near you that could swap engines for 1000 or so. I certainly would. If any coolant has leaked into the cylinders, I’d say the current motor is trash and likely has a bent connecting rod.
