I found signs an oil leak from the engine into the vacuum pump on the O-320-EG2 in my Grumman. It appears that the lip seal around the shaft in the accessory adapter has failed. I located the oil seal and vacuum pump to adapter gasket, but have had trouble finding the part number and a source for the gasket that goes between the vacuum pump adapter and the case.
Any leads would be much appreciated.
