I'm at 130K miles and the only sign of that is higher oil consumption - aprox. 1 quart every 500 miles or so. Other than that, the motor is original, pulls strong to 7800rpm (with Jim C. chip) and doesn't even leak anywhere. I'd say the S14 is a pretty solid motor when serviced correctly, even with high miles.
