I've found two more oil leaks in addition to the area of the vacuum pump, which I will be working soon.

The first one is at the seal in the upper oil pan the goes to the turbo drain tube. Does anyone know if you can change this seal without removing the whole turbo oil drain tube...the nuts at the turbo that connect the pipe look rusted and in a bad location to get to. Is it possible to just raise the tube to get enough clearance to replace the seal in the top of the upper oil pan?

The second leak is at the air cleaner to pan oil return line. Mine seems to be leaking at both the top and bottom. I put new o rings on both ends, but for some reason I can't mount the air cleaner on the car and connect the air cleaner connection when the bottom is fully connected. It looks like my pipe is either bent or too short, or my air cleaner isn't mounting correctly. The three rubber shock mounts for the air cleaner look good, but I don't know if they are the correct ones...previous owner did these.

Thanks for any advice.
