The 1989 Land Cruiser was sold with a single engine, the 4.0L naturally aspirated inline-six Toyota designated 3F-E, in one trim. On a truck this old the outcome of a repair usually rests on whether the work was held to Toyota's published figures for that combination — torque values, clearances and wear limits — rather than to generic numbers that ignore what changed from one model year to the next.

Known issues on the 1989 Land Cruiser. One recall is on federal record for this model year, and it covers the gasoline fuel system storage tank assembly: fuel leakage can lead to fire when near an ignition source. Owners have filed 3 complaints for the year, and Toyota has issued 7 technical service bulletins.
If that campaign — 91V110000 — was never carried out on a given truck, the tank assembly is the thing to verify before any other fuel work is started. Beyond it, keeping a 1989 Land Cruiser in service is a matter of holding the engine, the axles and the rest of the driveline to Toyota's own procedures and tolerances.
