318 oil leak

Yeah there"s no way that is getting buffed out. I dealt with the same issues on my divorced transfer case and I wound up just replacing all the yokes and seals. The easy route would be the sleeve and just give that a shot, but like Cruze said. what else could be wrong??? I didn't pay a lot for the motor so I can't really complain. I'm probably going to just tear it all apart and replace timing set too. Any recommendations on timing set? The engine is in a Kaiser Jeep M715 and it is mostly a grocery getter and cruise around truck.
