Obstructing maybe not the oil pan itself, but at least the removal of
the last couple screws that hold it...

Since I vented with that last post, I unbolted the engine mounts. I
will remove the oil pan tomorrow. Makes me wish I had just un done
the engine mounts to begin.
It seems with the engine unbolted (and the exhaust undone from the
downpipe) that I will have enough room now to remove the oilpan.
What a friggin pain.

I am glad I am not a toyota dealership mech.

I checked AutoZone to see what the instructions were. It says to remove
the differential...

Sorry...

Cheers for the link!

I did finally manage to get the oil pan off the engine. I unbolted
both engine mounts and the exhaust and hoisted the engine enough (with
the diff unbolted and flopping around as well). I could not,
however, pull it out from the bottom. I had to come out the top with
it after I removed the oil pickup. What a pain in the rear...

I thiink that's a job I woud have *paid* to have done!

Hope you kept a copy of the manual for further reference! These are
usually Factory manuals and come in handy.

Yes, the manual definitely helped untold amounts.

I finally got the thing back together... Let me fill you in on
everything I have done to this 3.4:

Was told that the engine needed head gaskets when we bought it. When
I put a socket on the crank bolt to undo it, I found that the bolt was
less than finger tight. The belt pulley keyway was wallowed as well
as the keyway on the crankshaft timing belt sprocket Had to purchase
*replacement* ones of those. Once I got the heads off and to the
machine shop, found out that passenger's side head was cracked.
Machine shop supposedly welded the crack then resurfaced the heads.
Did a pressure test and heads held pressure. Installed new water
pump, new oil pump, new timing belt and rollers...... got it all back
together.... I neglected to hook up the temp gauge the first time
we took it out because I just didn't see that it was disconnected..
Engine didn't run rough at any time, but after ten miles, the header
tank of the radiator blew out (stress fracture from previous bonehead
owner and a ditch). As soon as we saw steam, we shut down the
engine and let it cool... we called a ride, went back to the house,
then towed it home with the tow rig. Running it today with new
radiator and the gauge hooked up, the temp gauge keeps going up to the
red. Once it starts getting close to the red on the gauge, the
engine starts to run a bit rough.. Pull over and rev the engine in
park/neutral, the gauge will come back down to between 3/4 and
1/2.... The fan clutch doesn't seem to coincide with the gauge
position at all -- it engages randomly. Maybe an air bubble in
the system?? Should I jack the front end 20 feet in the air??
argh.... had this problem with a 735i once after replacing the head
gasket... took forever but finally burped the cooling system after
scaring myself too many times with the temp. gauge.. i am hoping I
haven't blown the head gaskets again already.... any input would be
great... damned V6s.... my mom's geo metro has more coolant
passages in the head than the 5vz.... no wonder the 5vz overheats
 >> Stay informed about: '96 Tacoma 4x4 Front diff removal 

Update:

Just went for a 20 minute drive. Engine runs smoothly, has great
trottle responsibility.

If I drive normally and let the engine go into 3rd and then OD and
chill at 1500 or so RPM, the gauge immediately starts to climb.
Shifting back into 2nd (and raising the RPM to 2000+) makes the temp
immediately start to plummet once again. The more I drive, the less
it seems to do this, but it still is worrysome. Hach, would
appreciate your input on this one.. this is the first 3.4 I've
done. Runs much better than I would have expected, 'cept for the
stupid overheating problem... It doesn't stall or sound rough
either. It sounded rough once today, but we shut it down
immediately...

One of the techs who used to post frequently here ran into a similar
condition that turned out to be something stuck in one of the coolant
passages in the block. Whatever was stuck came out when he disconnected
the radiator and back-flushed plain water through the system.

Since you seem to have a fair amount of experience working on engines, I'll
assume that you had the heater water valve fully open when you filled the
coolant and used a new radiator cap on the new radiator.

The random engaging of the fan clutch seems odd, you may want to remove it,
heat it up with a hair dryer or heat gun, and see if it locks up properly.

Also, is the fan shroud in place?

Hmmmm... sounds interesting. I guess I will try the back flush.
I'm sure something could have made its way into the coolant passages
-- probably a huge georgia brown recluse spider.. LOL Who knows.

I have to admit, I did do the heater valve fully open when I filled
it, but I have not bought a new radiator cap yet. I will purchase
one of those today.

After I posted my last message yesterday, we went for another drive.
Seems now the temp. gauge rides in the middle unless you move the
heater lever to 'cold'... if you have it on 'half hot' to 'fully hot',
no problems at all.

Okay, I 'll try that hairdryer stuff..
Yes, the fan shroud is on..
I'm sure i'll get this sorted eventually... it's nice to have some
people off which to bounce this stuff

It sounds like the little extra bit of cooling from the heater is enough to
prevent problems. Radiator caps are pretty cheap so start with that, and
check the fan clutch.

Replaced both... still doing the same thing. Once it cools down
again this afternoon, I'm going to backflush it..

The cooling system is not over-pressurizing, so hopefully the head
isn't still cracked/cracked again... argh, this is annoying!
 >> Stay informed about: '96 Tacoma 4x4 Front diff removal 

Flushed it this afternoon after it cooled down sufficiently. I let
plain ol' water run through there (put a flushing tee in place of the
heater valve -- i'm not cutting a $40 molded heater hose that would
take two weeks to get where I live..).. let it flush for at least 20
mins to half an hour..

I took the thermostat out before I did the flush.. closed the system
again and left the thermostat out of there. Filled with plain water
and ran the truck for at least 20 mins and drove it around the block a
couple times... (would have been enough to make the gauge start to
climb before without heater on). Couldn't get the gauge to come up
even to halfway... so .. Obviously, my test of the old thermostat was
bull$hit... I must have heated it too much and fail-safed it...

Needless to say, I feel rather idiotic! At least my brother is
smart enough not to overheat the thing..

Thanks everyone for the help! I appreciate it!
