Is my engine in my car any good? will it last a long time?

okay, i have a 1995 ford escort wagon, it has 236k on it with the Original engine in it. Its a 1.9L 4 cylinder with a manual transmission. i kept up with the oil changes, spark plugs, air filer etc. so im just wondering if the engine it will last a long time. its the same motor and transmission since brand new. Thanks!
