Toyota Trucks: Oil Pump Replacement - 3VZ-E

Hi Ben,

It can be a bear. I just did mine (1988 4Runner) while I was taking care of
some other stuff and I would have been pretty proud if I could have done it
in that amount of time.

The oil pump is bolted to the front of the engine behind the crankshaft
timing pulley. As such, the timing belt and the pulley have to be removed.
This, of course, involves pulling the radiator, power steering pump, fan
pulley assembly, etc. Once you can access the oil pump from the front, it
can be unbolted from the engine and oil pan. However, the sump has to be
unbolted from the bottom of the engine. This means that the oil pan and
baffle have to be removed which, in turn, means that the front differential
must be pulled (for 4WD.) Actually, the baffle doesn't have to be removed
but I did mine so that it could be cleaned and resealed to the motor to
prevent leaks.

Experienced mechanics may have some shortcuts but the above was according to
the shop manual for my engine/chassis combination. Also, if someone were to
promise me a quick and easy method, my first concern would be the potential
for oil leaks. It's probably better to get everything the hell out of the
way and do the job right.

Good time to have the water pump, idler pulleys, and timing belt checked.
Also, care should be taken that the new oil seal (this is the front
crankshaft seal) is installed properly and, specifically, that there are no
burrs on the crankshaft. Otherwise, there could be leaks. This is pretty
common. I installed a Redi-Sleeve on mine to ensure the oil seal had a nice
smooth surface to ride on. Others on this list had recommended that to me.

Obviously, it is also a good time to take care of any leaks from the oil
pan.

HTH,

Luther

About right. Maybe even a little light.

Inasmuch as the Democrats are complaining on how long the war is taking,
consider this:

It took less time to take Iraq than it took Janet Reno to take the
Branch Davidian compound. That was a 51-day operation.

It took less time to find Saddam's sons in Iraq than it took Hillary
Clinton to find the Rose Law Firm billing records.

It took less time for the 3rd Infantry Division and the Marines to
destroy the Medina Republican Guard than it took Teddy Kennedy to call
the police after his Oldsmobile sunk at Chappaquiddick.

It took less time to take Iraq than it took to count the votes in
Florida! TWICE!!!!!

Damn our military is GREAT!!
