Engine CA18ET

Symptoms:
- Loss of power or turbo lag
- Excessive smoke from the exhaust
- Engine overheating
- Rough idling or stalling
- Oil leaks around the turbocharger and engine seals

Diagnosis:
- Check for boost leaks in the intercooler piping and hoses
- Inspect turbocharger for shaft play or damaged blades
- Perform a compression test to assess cylinder health
- Examine the cooling system for leaks or blockages
- Look for oil leaks around turbo seals and gaskets
- Scan for any engine fault codes if equipped with electronic controls

Fixes:
- Replace cracked or leaking intercooler hoses and clamps to restore proper boost pressure
- Rebuild or replace the turbocharger if excessive shaft play or damage is found
- Repair or replace worn engine seals and gaskets to stop oil leaks
- Flush and refill the cooling system; replace faulty thermostat or radiator if overheating persists
- Clean or replace the idle air control valve and throttle body to resolve rough idling
- Regularly change engine oil and use high-quality synthetic oil to protect turbo bearings

Prevention:
- Maintain regular oil changes every 3,000 to 5,000 miles using recommended oil grade
- Inspect and tighten all intercooler and intake hoses periodically to prevent boost leaks
- Avoid prolonged high RPMs before the engine is fully warmed up to protect the turbo
- Monitor coolant levels and condition to prevent overheating issues
- Use quality replacement parts for turbo and engine seals to ensure longevity
- Follow manufacturer’s maintenance schedule closely to catch issues early
