You did not say, but what year/model rig do you have? Not that relevent, as it has to be an earlier rig if it has a 3.0.

I have an '89 4Runner with a 3VZE. Since I can't go to sleep, and the 10 month old just went to sleep, and the wife is asleep, I grabbed the FSM and looked through it. I could not find a specific procedure for just pulling the oil pan.

Assuming you have some type of IFS front end, there is not a lot of clearance to get the pan off with the motor installed and the IFS in place.

You might, and I do not know this for sure, be able to get the pan off by putting a hoist on the motor, disonnecting the exhaust, motor mounts, radiator hoses, removing the fan shrowd and fan, etc, etc, and then pivoting the motor/tranny on the tranny mount. Might, but that seems questionable, and a lot of work, and risky.

Other path is to pull the axles shafts, remove the sway bar, remove the front driveshaft, and drop the front differential assembly on the ground. Then you could easily pull the pan with the motor in place.

That's my opinion, for what it is worth.
