Transfer case 4wd actuator leak question

Hello all,
I recently sold my 2012 DC and upgraded(?) to a 2004 limited DC. Overall I'm pretty happy with the smaller size and slightly larger cab. Plus it fits my lifestyle and driving style much better (slow and steady).
After driving it around this week, I noticed a slight oil-burning smell that I chalked up to a valve cover gasket leak. But after inspection, I realized that what is happening is this: There is a triangular cover on the side of the 4wd actuator that is held on with three screws. Two of them were/are missing (lower two) and I'm guessing that while spinning it was throwing out some of the gear oil, and the wind was blowing it onto the exhaust.
My questions are thus: Can anyone point me to a replacement gasket? Or should I just use RTV sealant to reseal the cover?
I assume I need to check the transfer case fluid level, as they appear connected. Or do I need to fill this tiny reservoir directly? Does the transfer case fluid circulate through the actuator?
I don't want to screw anything up in the driveline, and could use some help if anyone knows these systems.
In the pictures I'm attaching, I have already removed the final screw and cover - I wasnt driving around like that. The top screw was still attached and holding the cover in place, but the lower two are gone and the cover appeared to be allowing fluid out at a rapid rate.
Cheers!

 

First thing I would do is plug your VIN into the parts system and look at the exploded diagrams.

You should find the actuator and whatever was originally there, with the fasteners, in the Transmission and Driveline section, probably under the Transfer Case & Extension Housing.

 

Thanks for that Shifty, I didnt know that resource existed. Unfortunately it doesn't quite show the parts I need. It shows one side of the actuator, and the exploded diagram, which has helped to make sense of how the system works, but not the cover and bolts on the other side (which is what I'm looking for).
After studying the exploded view however, and looking at my part, it seems that the actuator motor spins a gear in the "x" axis, which drives the actuating rod (p/n 36313F) forward and back within the transfer case in the "y" axis (90 degrees to the orientation of the motor shaft). The issue I'm having is that the small metal cover that covers the gear is what came loose, allowing what I now think is simply some of the transfer case gear oil to spill out when driving.
Does this sound right? It seems a pretty easy fix to seal the cover back to the actuator with RTV and use blue locktite to ensure the bolts don't back out again. I would also check the transfer case fluid and make sure it isn't too low.
Thoughts? Feel free to correct me if I'm wrong about any of this. I really don't want to screw up my transfer case or actuator.......
In the diagram I'm attaching, I drew the location of the three small (M4?) bolts in red.

 

I see what you're saying. I'd need throw some eyes on my actuator (which I can't at the moment) to see what the hell I've got on mine - the red material makes it look like there was a cardboard gasket there. I'm wondering if you can't just toss a blockoff plate on it, but I can't remember what the hell is there. Maybe someone else can chime in with pics they've taken of their actuator bodies so we can see what's there.

I take it you've tested shifting into 4HI, and all seems to work right, the button's light goes solid within a couple of seconds?

 

Yep, 4wd works flawlessly. The truck ran 60 miles in 4HI yesterday with no problems. Thanks so much for the input, I really appreciate it.

 

Take the one good bolt to the hardware store, figure out its thread dia and pitch, then buy three shiny new ones. It looks like two fo the bolts are broken, so you'll likely have to drill and re-tap (You may want to remove the actuator before do this. Good thing...you have to remove that cover and the gear to remove the actuator). Toyota FIPG, or Permatex Ultra Black will seal it when you put it all back together.

Make sure you read up on how to remove/replace the actuator correctly, or you'll mess up the switching/timing and have a flashing 4wd light (don't ask me how I know about this....)

 

Well crap!! You're right, two of the bolts are indeed broken off in their housings. Guess I'm doing exactly what you said, pulling the actuator and repairing everything.
So much for a 10-minute fix!
Thanks again to all. I'll post up when repaired (or if more questions arise).

 

The below video shows the little gear that needs removed before acuator can come off.

 

Thanks BubbaW, I just watched that video. It's the two lower bolts on the little triangular cover that I thought was missing, but turns out are broken. And all the gear oil has leaked out, blown down the driveline and onto my exhaust. Thats what was causing the slight "burning oil" smell" I mentioned in my first post.
I'm gonna pull it and (hopefully) extract the bolts using easyouts. Then reinstall everything. But that probably wont be until the weekend.
Thanks!

 

Thanks to everyone who responded. I did exactly as recommended: Removed the actuator following the guidance of the video, drilled and retapped the broken bolts, reinstalled the actuator and cover (with nylock bolts backing the threads), and added a small amount of 75-90 gear oil to top everything off. I then cleaned the exhaust as best I could with brake-clean to remove the residual gear oil that was causing the burning oil smell. It's already doing better.
Thanks again to everyone for the advice. I really appreciate it.
