Oil leak

[Benjamin D]

Hi I have a 51 m37 it’s been leaking oil so I did a dye test. I’m leaking from under the bell housing and it seems like oil is getting blown under the truck , it’s all over back of transmission and transfer case, I even saw green dips off the rear differential. But the most alarming is I saw green on the line that goes from bottom of the carb to the intake manifold, and I had green dye show up in the oil bath air cleaner. Any help would be be appreciated, thanks.

Perhaps you might check the routeing of the vacuum & atmosphere lines for the several fording destinations, looking for improper connections.

Also, pull the PCV valve and make sure it isn't plugged.
