The Not So Mighty Toyota Land Cruiser, And Its Turbochargers

The Not So Mighty Toyota Land Cruiser, And Its Turbochargers

The Toyota Land Cruiser 200 Series Diesel V8 (4.5l) Is The First Twin Turbo V8 Diesel Engine Vehicle By Toyota.

A Twin-Turbo Variant Was Introduced In September 2007 And Fitted To The 200-Series Wagon Land Cruiser.
The Twin Set Up Is An Ihi Turbo Left And Right Side Configuration.

There Is Some Information About The Problems Owners Have Had With The Twin Turbo 200 Series Relating Excess Oil Use.
Some Of This Appeared To Relate To Faulty Oil System Vacuum Pumps And Problems With The Oil Strainer Blocking With Sludge.
Others Believed Excess Oil Consumption Related To A Problem With The Seals In The Ihi Turbo Chargers And Actually Had The Turbocharger Seals Replaced.
As Some Of These Issues Relate To The Turbocharging Of The Engine (And Some Opinions That The 200 Series Is Too Heavy On Fuel), A Few Have Gone Back To The 100 Series.

Excess Oil Use Aside, More Serious Turbo Problems Appear To Come From Dust Ingress Into The Ihi Turbos.


The Left Side (From Driving Position) Turbocharger Appears More Prone To The Dust Problem Than The Right Side Turbo, Or Driver’s Side Turbo.
And Vehicles That Are Driven In More Remote Areas On Unsealed Roads, Especially Those Used In The Mining Industry Are More Prone To This Foreign Object Damage.
The Right Hand Side Turbocharger Due To Its Position Is Less Likely To Suffer Than The Left Hand Side, But If One Of The Turbos (E.G. Lhs) Has To Be Replaced Then It Is Recommended Best Practice To Have Both Turbochargers Replaced At The Same Time, But Not Entirely Necessary.

As Always, Engine Sludge Build-Up Can Be A Contributing Factor In Turbocharger Problems.

More So Than For The Older 6 Cylinder Diesel Engines, For The Landcruiser 200 Series Diesel V8 It Might Be Worth Doing A Full Service Before The Usual 10,000km Mark.
And The Most Critical Need Is For The Oil And Filter To Be Changed At Every Service, The Air Filtration Ever Few Services.

Oil Sump Levels Must Be Neither Under Or Overfilled. An Over-Filled Sump Creates Higher Pressure That Pushes Against The Oil Flowing Out Of The Turbo Oil Dump Lines.

It Goes Without Saying And It Is An Absolute Requirement To Have Oil And Filter Changed When A New Turbo Is Installed.

The Above Outlines Some Land Cruiser Ihi Turbo Problems, And Some Ways To Help Prevent The Issue Re-Occurring.
