Since I was cleaning things I decided to take out the oil filler tube and wipe all the previous caked on oil and dirt off of it. When checking out the tube I noticed on one side of the inside there was some holes there. Are these vent holes or something else. Should they be clear of debris and what should I use to clean the inside. Thanks again, Cliff
