I have a 1966 Cherokee 180 with fixed pitch prop. I have noticed some
oil streaks on the back plate of the prop spinner, apparently seeping
out between the prop and flywheel. Anyone have an expereince with this?
Is there a plug in the front the hollow (I assume) crankshaft that
could be leaking? Is this a common problem? Thanks for any info.

There is a seal at the front of the engine where the crankshaft exits.
It's glued in place and the glue can come loose.

Replacing it takes a few hours, as the prop needs to be removed and
replaced, but shouldn't be a big deal for an experienced technician (if
that's what's causing the leak).
