I have started the engine rebuild process. Prior to cleaning in "soup" and while taping up all orifices I noticed two small open holes (about 1/8") in the clutch cover. One at top front exposed after removing the oil pump and one facing the front. I have searched and the only thing i can find is a picture in the rebuild process clearly showing the top hole. What is the purpose of these holes? Venting? Seems odd to have places where dirt can enter.
