Oil leak under the M38

[rob love]

First off, does the oil have the distinctive smell of hypoid, or is it engine oil? The rear engine seals on the Willys were not really what you would call perfect. Same goes for the front transmission seal, it was a felt washer, and not a true seal.

There are only so many places a jeep can leak from the transmission/t-case. Spray the whole area down with engine shampoo and then pressure wash everything down there. After a quick run, the source of the leak should become obvious.
