I just bought a 1977 FJ40 and found an oil leak coming from the head, it is right behind the air cleaner bolts on passenger side in the head, it has some sort of plug but when running has a constant leak. Any ideas how to fix or what it's there for

That's the oil galley plug. It's pressed in. That's where the head was drilled for the oil passageway to the rocker assembly. Search it up. It can be drilled, tapped and plugged.
Get to it soon. if it blows out, you'll loose oil & pressure quickly and do serious damage.

what is THIS for? well whatever it is it's leaking...
This is a pic of the head and the #5 spark plug. The culprit is the white thing circled in the middle, between the #4 and #5 spark plugs. What is it/its purpose? Kinda need to know since it's leaking like MAD. Is it a replaceable plug of some sort? Is there anything I can do to stop this thing...

Appreciate it, fixing this today.
You will likely need a right-angle drill to get in there, or at least a compact one.

Yup, I am already back on the road, not too bad of a job, loctite still had a leak so I used some permatex thread sealant made for oil and gas applications on a m8x1.25 set screw , holding now.
Nicely done! Sounds like you did it just right. I think I JB-Welded mine in place, and zero leaks for several years.

Even if you catch it before any damage it makes mess of the engine bay if it pops out.

How do I get some legroom in this ol girl?
Fabricate steel mounts that move the driver's seat back about 2". It's a blessed 2", however, and fixes the legroom problem for most people. You can't go much further back because the back of the seat tracks will be close to hitting the tub. There are pix and threads, but if you study it, it will make sense.

Thanks! I would never have picked it, but once I saw it in person I really like it.
