Location of Oil Pressure Sensor and Oil Pressure Relieve Valve
I have a 1989 Land Cruiser with a 2-HT Diesel Engine
The vehicle is new to me and I am trying to locate the electric Oil Pressure Sensor and the Oil Pressure Relief Valve which I suspect is dirty. Can anyone help me?

Re: Location of Oil Pressure Sensor and Oil Pressure...
The oil pressure switch is on pssenger side, lower engine area,beside oil filter, mounted in engine block. The pressure relief valve is in the oil pump, in which case, you have to drop the oil pan,and take off the oil pump.

For 1989 Toyota Truck Land Cruiser 4.0L FI 6cyl, check this diagrams, according with your Engine Code...

When installing a new thermostat always use a new gasket. Be sure
that the thermostat is positioned with the spring down or into the
housing. On 3VZ-E engines, the jiggle valve (looks like a small rivet in
the edge of the thermostat) must be at the top or 12 o'clock position.

Install the water inlet. Install the bolts finger-tight until the
inlet is positioned exactly. Tighten the bolts to 10-14 ft. lbs. (13-19
Nm). Overtightening will break the ear off the housing and spoil your
afternoon-don't do it.
Install the hoses and wire connectors removed for access. Make
certain the coolant hoses are not kinked or twisted after installation.
Do not overtighten the hose clamps.
Fill the cooling system with coolant.
Start the engine and check for leaks. Top off any fluid levels.
lifters noisy,lots of miles on engine?as oil pressure gets higher and engine warms up(everything expands a little and quietens a little)it gets better,try fresh oil thats thicker for worn engines,and or check tappets(valve adjustment)if its applicable to this engine

Take the Vehicle back to the Installer/Supplier, for a Free of Charge CHECK and ADVISE under New Engine Warranty. If the OIL PRESSURE is LOW, when starting up from COLD, there is a genuine fault, so do not drive any distance.
Whoa! Never remove the oil filter while the motor is running. Alot of vehicles have valve cover leakage and it is easily repaired with a new valve cover gasket. It is completely normal for the dipstick to be dry until the motor is off and all oil has drained from the upper compartments of the engine including the area where the oil lubricates the valve guides. Most mechanics will place the vehicle on a completely level area and then wait 15 minutes or so after the motor is off to check the oil. The dipstick will always show that you have low oil if you check it while the motor is running as the oil is elsewhere doing it's job. If you replace your valve cover gasket be sure to not overtighten and tighten in a random crisscross pattern so that you have uniform pressure all along the gasket. There are torque guides for this and you can usually get them from your local parts house. Buy a good torque wrench also.
