Because most street machiners are on a budget, they opt to reuse many items, like the oil pan. If you do reuse the oil pan, thoroughly clean out the sludge buildup inside. In addition, check for any cracks or dents that could wreak havoc later on. If the pan is in bad shape, you may wish to update to a new oil pan, such as from Milodon. Milodon pans can even be ordered with special oil-control baffles, if that suits your fancy.
