Landcruiser 200 Series Diesel V8 IHI Turbo Problems
Turbocharger Replacement and Preventative Maintenance
The Toyota Landcruiser 200 Series Diesel V8 (4.5L) is the first twin turbo V8 Diesel engine vehicle by Toyota.
The 1VD-FTV engine was first fitted as a single-turbo variant and first used in Australia from March 2007. It was fitted to the 70-series Land Cruiser range.
This was a single Garrett GTA2359v turbo as available here, but it is not the focus of this page.
But 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 with an asymmetrical left and right side configuration.
There is some talk about problems relating excess oil use with twin turbo 200 Series.
Some of this appears to relate to faulty oil system components. With vacuum pumps and problems with the oil strainer blocking with sludge indicated.
Others believed excess oil consumption related to a problem with the seals in the IHI turbo chargers. Thereby remediated by replacing turbocharger seals.
As some of these issues relate to the turbocharging of the engine, a few have gone back to the 100 Series.
The MAIN reason Turbos Fail on the 200 Series Landcruiser
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. Dust appears less of an issue on the right side turbo, or driver’s side turbo.
And vehicles that are driven in more remote areas on unsealed roads, like those used in the mining industry, are more prone to this foreign object damage (FOD).
If you own a 200 series diesel V8 and it has been used like this, there is a high possibility the turbo may already have FOD. It just may not exhibit any symptoms yet.
Due to its position, the RHS turbocharger is less likely to suffer this acute FOD than the LHS. However, 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 it is not entirely necessary, and often dependent on finances available.
Air Filters and the Good Oil on the 200 Series Land Cruiser
Below is some brief advice on how to prevent the turbo problems.
You will also find a more economical choice to remedy the Land Cruiser 200 Series V8 IHI turbo problems mentioned above.
These ‘dusted’ original IHI turbos are more likely if the original OEM Toyota air filter has been removed and replaced with an aftermarket one.
In this case, it appears that an aftermarket system is not better.
But the OEM filter will not necessarily completely cure the issue. However, anecdotal evidence suggests it may slow the problems occurrence.
So perhaps consider changing back to OEM filtering and perhaps change that filtering system more often.
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 Land Cruiser 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 every few services.
Neither under or over fill the oil sump. 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.
