Most common problems, symptoms & fixes for the RT OHC engine.

Engine RT OHC in the Ford Escort 1.8 Diesel (1988–1998) commonly faces injector clogging and turbocharger wear. Diagnose injector issues by rough idling or poor acceleration; clean or replace injectors as needed. Turbo problems manifest as loss of power or smoke; inspect for shaft play and oil leaks, replacing worn turbos. Regular oil changes with quality diesel oil prevent premature wear. Fuel filter replacement every 20,000 km avoids clogging and fuel starvation. Check timing belt condition and tension to prevent engine damage. Maintaining cooling system health prevents overheating. Overall, routine maintenance and timely part replacements ensure reliability.
