Why does the Left Hand Bank Turbo Fail on the 200 Series Land Cruiser?
The 200 Series Land Cruiser has a 4.5L 1VD-FTV engine fitted with a Left (LHS) and Right (RHS) bank Turbo, in a twin-turbo set up.
OEM turbos fitted at factory have v-spec designation VB22 / VB36 (right bank) and VB23 / VB37 (left bank).
Each unit is not identical in housing structure, due to the unique fitment position of each unit.
So they are not inter-changeable between the driver and passenger side turbo banks.
The Passenger (left bank from seated position) side Turbocharger, is more likely to fail earlier than the Driver side (right bank from seated position) Turbocharger.
Why does this happen?
There are 2 reasons:
1) Due to its unique intake position, the LHS (VB23 / VB37) turbocharger is more likely to suffer Foreign Object Damage (FOD).
What can you do to prevent this?
Change the air filter on a regular basis, especially if you operate the vehicle in a dusty environment such as gravel and dirt roads.
2) And due to its position in the exhaust system, the LHS turbocharger has a higher load of carbonized gases from the EGR (Exhaust Gas Reticulation) system.
The EGR system takes exhaust from the diesel’s manifold and adds it back to the combustion chamber.
An EGR functions to to reduce emissions, and reduce the temperature in the combustion chamber.
But in the process, sooty gasses are passed back through the system (before it passes out through the particulate filter), affecting the LHS turbo more than the RHS turbo.
Unfortunately there isn’t an easy solution to this issue.
