have a problem with oily exhaust fumes under the cowl, I removed the top cover on the drive shaft housing and found a 2 strange holes that looks as if they are not original, cant see them anywhere in the manual, when the engine are running exhaust fumes (and water ????) comes out of the hole...
I noticed that when running the engine with cups and a water hose, water is comming out between the gearhousing and the driveshaft housing, looking in my service manual it seems there is not supposed to be a gasket there, so is this normal or do I have a problem?
