2005-07 Toyota Hilux/Prado With 1kd-Ftv Engine: Injector Seal Failure
Initially, The 1KD-FT Enigne Had Copper Seats At The Base Of The Common Rail Injector To Provide A Seal Against The Combustion Chamber. These Seats, However, Can Fail And Cause The Following Problems:
Blow-By Gases Enter The Tappet Cover And Mix With The Engine Oil - This Bakes And Carbonises The Engine Oil;
Blow-By Gases Block The Oil Sump Pick-Up;
The Engine Can Be Starved Of Oil;
The Lack Of Lubrication Cause Excessive Friction And Heat, Causing The Bottom End Bearings To Melt And Engine Failure.
Symptoms Of A Failed Common Rail Injector Seal Include:
We Recommend That Owners Of Vehicles With The 1kd-Ftv Engine Which Has Copper Injector Seats Have Them Replaced With The Updated Injectors And The Oil Sump Pick-Up Cleaned If There Is Evidence Of The Copper Injector Seats Allowing Blow-By Gases To Pass. At Each Service, The Oil Sump Pick-Up Should Be Inspected And, If Required, Cleaned By Removing The Oil Sump Covers, Taking Out The Screen And Spraying It With A Carbon Cleaner Or Degreaser.
05-07 Toyota Hilux/Prado With 1kd-Ftv Engine: Injector Failure
It Is Not Uncommon For The Injectors In The 1KD-FT Engine To Fail Around 120,000 To 140,000 Kilometres, Though They May Fail As Early As 75,000 Kilometres Or Last 250,000 Kilometres. Symptoms Of A Failing Injector Include:
A Loud 'Knock' Noise That Is Audible When The Windows Are Down, Particularly When The Engine Is Cold;
The Shorter Lifespan Of These Injectors Is Attributable To The High Fuel Pressure (From 30 To 160 Mpa), Multiple Injections Per Combustion Stroke, Small Tolerances And Fuel Quality. As A Preventative Measure, It Is Recommended That The Injectors Be Replaced Every 100,000 Kilometres. At Each Service, It Is Recommended That A Diagnostic Test Be Conducted To Measure Feedback Volumes Or Total Volumes For The Injectors To See If They Are Working Properly.
