Toyota Trucks: 3VZ-E oil seals?

The front crankshaft seal is mounted in the body of the oil pump. I don't
think you can replace it without removing the oil pump first, which is quite
a job because it means dropping the oil pan (to remove the sump) which -- in
the case of 4WD -- means pulling the front differential. That is how I
recently did it and the results have been very good. It was definitely
worth doing right and it gave me a chance to check the oil pump and reseal
the oil pan and baffle. A friend's shop had replaced this seal (2x) in the
past and it leaked like a sieve both times. Now it is as tight as a drum.
I suspect they took some sort of shortcut as it's not exactly rocket
science.

I haven't had the pleasure of doing the camshaft seals. However, it is my
understanding that the camshafts need to be removed to do this job properly.

That's the one that looks the the easiest to do in place. I'll have to decide
what to do with the crankshaft seals once I get the pulley's off. It also looks
possible to replace the #2 idler pulley after the rear timing belt cover is
off, without removing the intake manifold. Anyone BTDT?

The number 2 pulley bolts to the intake manifold. You will have to pull the
air intake chamber to access the four mounting bolts. So, you are correct
that you do not have to remove the intake manifold. Unfortunately, the
hardest part of removing the manifold -- getting to it by pulling the intake
chamber -- will nonetheless be required.

Luther, yesterday I spent some quality time with the front end of my truck
engine. The camshaft and crankshaft seals can both easily be changed in place.
The #2 idler pulley can replaced without removing the air intake chamber, mine
was dry and loose, gear wrenches help here. Thanks.

What year was your's again? I'm not a professional mechanic but I don't see
how the crank seal could be replaced on mine without sliding the oil pump
off as the seal is flush with the oil pump. I suppose a hole could be
drilled in the seal and it could be snatched out with a puller. Also, this
is the way the shop manual says to do it (pulling the pump).

Sorry that I gave you bad advice. Perhaps the 3VZ-E changed a bit with the
years and/or I need to be educated. One of my head gaskets just blew and I
am going back in. Let me know what the procedure is and I will see if it
will work on an '88.

Gary and Luther,

I had a 22RE that had a front seal go out, and I took it to the dealer
expecting the pull the head off scenario (as the Chilton manual said would
happen), but they took about 2 hours to somehow grab the seal with the pump
in place. About $150 (about eight years ago). What a pleasant surprise!

Toyota somehow improvised and came up with a tool to remove it. This is an
example of the kind of things that should be done as it benefits the
consumer!

Your "mileage" of course may vary with a different motor.
