I went ahead and installed the fill tube in the miter box and that went well. Then I drilled a hole on the dip stick handle to let air out, like in Boomer's pic above. I did all this at the garage where I store my bus. Then tonight I brought my bus home so I can finish installing my cruise control tomorrow (that will be another project eagle post). Anyway, when I got home I opened the engine compartment and there was no oil spilled out anywhere.
