At the end of every year we clean out the old to make room for the new. Today we put together all the LS oil pans from 2013 to be recycled. On most LS builds we are not able to use the LS pans for clearance issues. We install our new custom built pans and acquire the old pan. Unfortunately these pans are not a commonly used item so they are sent to the recycler to be turned into new products.
