'Phooey. This happened on the way to a fly-in yesterday and kinda ruined my day plus the appearance of the front of the airplane.

Can someone in the group tell me when I can obtain a new seal and how difficult a job it is to replace?

Thanks,

Ranger Mike'

I am assuming you have a Ranger engine, if this is the case sorry but there is
no prop seal. It uses a slinger designed into the bearing retainer to keep the
oil within the engine nose case, if you blowing oil past thr bearing retainer
you may have bigger problems. There a few Ranger experts who may have seen this
before like the Denests, but my guess would be the crank case has had a build up
of pressure. Make sure your breather is clear of blockage, if it is then you may
want to perform a compression check for piston blow by.

'Hmmm....I'm going through the Ranger overhaul manual today. I'll check the
breather but doubt that's a problem. I've had to replace jugs from time to
time due to stuck rings but never had this issue before. I haven't pulled
the prop yet but wonder if it's possible the bearing has issues. Everything
feels tight and smooth.

Thanks for the imput Jim.

'Mike,

If it happened suddenly, you ought to clean it up and then run it long enough to see where it is leaking. The vertical tube between the cam housing and the crankcase could be the culprit. Also check the nuts on the front flange on the crankcase. Something like a broken ring could cause a sudden increase in crankcase pressure, so a compression test is in order.
