How hard are these Gen 1 Tacoma oil pans to reseal? I've read they don't have gaskets but some kind of polymer applied to them. I just got the truck and it's on my list of things to do. Thanks!

The first thing to do is clean off all the oil, and then observe over several days of driving, to verify where the oil is leaking from. It appears it's a 2wd, which would make the job of pulling, re-sealing, and installing the pan easier.

From the factory the oil pan doesn't have a gasket and uses Toyota FIPG. It was/is the same for our 1993 Toyota 4x4 pickup. When I overhauled the engine to replace the timing chain, I removed the oil pan and found broken plastic chain guides in the pan. It did not have a gasket. I used FIPG and reinstalled the pan onto the engine block. Use Toyota FIPG or Permatex Ultra Grey RTV.
 
Also if you have to remove the pump pickup to completely get the pan off, order the gasket for the pickup interface to block. Ran into this on a '93 4R 3.slow
 
It is a straight forward job - cleanliness and prep are key. Remove ALL of the old sealer, brake clean it all very well and I have actually used "The Right Stuff" as a substitute sealer and works the same. Be sure to run a good clean bead all the way around but do not make it so wide it squishes out and falls in the pan. Slightly tighten the bolts in a criss cross manner to evenly bring the pan up. Wait about 10 mins and then finish torquing to spec. Also - read the sealer directions closely and follow.

I've even used good ol' Ultra Black which is fine if you're willing to wait the cure time. It's inexpensive and readily available. Ultra Gray is often next to it on the shelf, but if a place carries only one it's usually the Black
