It’s the love and hate choice.
Exceptional chasis for offroad, exceptional engine output and towing capacity (when it works).
Yet also famouse for so many overheating issues and injector issues.
Due to the high output tune of this engine, it generally runs at a high temperature. Over time, injectors would have knocking issue.
Black smoke is also very common, mainly due to injector nozzle damage and turbo failure.
Customers normally experience much quieter engine and improved fuel economy after replacing injectors.
Common injector caused problem:
1. Black smoke
*Poor atomization of fuel ( spray quality) -- poor spray quality will cause smoke or engine knock. Require replacement of injectors
*Leaking injector from nozzle nut, causing diesel to mix up with engine oil. The turbo is then affected by poor oil quality and spins up slow, causing black smoke during gear change or under load.
**Injector seating blow-by, require seat cutting and injector replacement.
2. Engine knock
If knocking affected by temperature, normally caused by faulty injector.
3. Rough running or misfire
Generally injector failure or blown head gasket
4. Hard to start
*Yd25 hard to start issue is generally related to injector or pump.
5. Poor fuel economy
If turbo, compression and transmission all in good condition, injector is mainly responsible for fuel consumption issues.
6. Bad exhaust smell
Mainly caused by injector poor atomization and seat washer leaking compression (blow-by)
