Run the engine on the ground at ~2000 RPM and note the reading on the air speed indicator. If it's more than 50 MPH (if I remember correctly) then the crank case pressure is too great. If it's ok, try the same test in the air. If it's high then, the front crank seal is probably bad and ram air is getting in. Pull the fitting out of the case and check to see if it extends inside the case. If not, you can silver solder a tube that sticks out about 1 inch. This prevents oil from running down the case and getting blown into the vent. Also, many folks have routed the vent line so that it goes up from the case before heading down to the cowl exit. You only need about an inch of climb to make a difference. Check out the magazine article for more ideas. Good luck (You shouldn't be forced to wash the belly every time you fly) John __________________________________________________________________________ ______ To unsubscribe from this list please send mailto:[EMAIL PROTECTED] _____________________________________________________________ Who will win the Oscars?
