Initial Checks
- Check air intake system for cracks or restrictions. Inspect exhaust system for leaks or restrictions.
- Check air intake system and exhaust system for signs of oil leaks from turbocharger. Oil leaks can be caused by worn oil seals in the turbocharger.
NOTE:
Turbo pressure may be referred to as boost pressure. Tachometer is required when checking turbo pressure. If installing tachometer, ensure it is connected to proper terminals. For tachometer connections, see IDLE SPEED & MIXTURE in ADJUSTMENTS
