making it work

 I figured if the oil return out the pump was bent, then maybe a straight fitting out of the block might work. The issue is that toyota uses such fine threads I couldn't find a fitting like this that would screw right in. I had to use some kind of adapter but unfortunately that made the whole thing stick out too much and I was still dealing with an awkwardly sharp angle for the hose.






At this point, I said F it and made it work. The kink in the hose doesn't look good and I was a bit nervous that running it like that might build up too much pressure in the pump, but it worked fine and I tested the line by bending it and blowing through and it still had flow.It looks bad but it worked out. 




I ended up finding a Chinese made aftermarket vacuum pump with the correct oil return angle from ebay. I ordered it, but while I waited for it to arrive I drove the Cruiser like this and it was fine.

Found another vacuum pump

 So my brother came through for me and sent me a spare vacuum pump he had. (He also sent me the old o ring it had.) His pump looks the same as my old one except for one minor difference. The tube for the oil return line bends downwards and the one on my old one came straight out. This minor difference made it very difficult to attach the oil return hose, I ended up cutting the hose in an attempt to get it on the pump better but it didn't work out.




In order to replace the hose I had to remove the banjo fitting's barbed end from the crimp. I had to carefully use a grinder to get the crimp off. This was a bit tricky but it worked out.





However Even after replacing the hose, the angle was still too awkward to make it work.

Vacuum Pump snafu

 One of the issues I've been having with this Landcruiser is that she leaks a lot of oil. I noticed excessive amounts were coming from the seam between the back of the alternator and the vacuum pump. The pump is held on by three little bolts, I figured I'd open it up and have a look.





Sure enough, when I got the vacuum pump off I saw what the problem was. There is supposed to be a rubber O-ring that forms the seal between the alternator and the vacuum pump. Looks like when the previous owner replaced the alternator they forget to put this o ring back in. 





I measured the grove to figure out the size of the o ring and then bought a generic one at the parts store. Unfortunately I did not realize that the proper OEM o ring is much thinner then the one I got, and when I tried to tighten the vacuum pump back in I ended up cracking the housing. Bummer. Now I need to replace it.
