It's time to change the oil in the H. Did that yesterday and removed the old oil filter. I noticed there was no gasket at the mating surface of the cover. I can't for the life of me remember if there was one there before or not - it doesn't seem to leak there, so I'm wondering if anyone knows if it should have a gasket or not? Also, I know it takes six quarts of oil, but is that with or without the amount taken up by the filter?
