My 1995 Ford Escort lx is hemoraging oil from the engine its a 1.9l 4cyl what engine can I swap into it?

Leaking from the main seal, not enough money to fix it. Thinking of throwing in a used one from a car at the wreck yard, just want to know which engines will fit/be compatible.

If you can pull the motor to switch it, you can pull the motor to replace the rear main. The seal is a lot cheaper than a used engine

You can buy the seal kit for under $20 and the labor is the same
