What would happen if your crankcase breather was blocked?

Re: crankcase breather

Pressure will build up in the engine case - could blow a nose seal or someother path it can find to escape..jack

That's why there is a hole in the tube above the exit of the airframe.  If the tube ices over, it can still breath.  Blocking it causes many pressure issues--all are bad, too!  <ng>

Re: crankcase breather

Nose seal...goes around the crankshaft, right behind the prop....
You'll notice it if it leaks....

Jim,  Really hard to say....Do you have a reason to believe you may have a vent problem?  I wouldn't think your vent would be that easy to plug....jack

Re: crankcase breather

The crankcase pressurization would occur very, very quickly after the breather is blocked.  Immediately.
