It is a bit of trouble to change the oil filter on the 5.7. After struggling with that skid plate a couple of times I got smart and cut a 6" square hole under the filter housing and had a sheet metal shop weld 4 10 MM nuts on the backside of the skid plate. I cut a scrap piece of 16 ga ungalvanized sheet metal to cover the hole-had to form it a little to match the bend in the skid plate. Did the forming with a dead blow hammer and vise. Painted the cover plate black to match the skid plate. Smoothed all the edges to make it user friendly and oil filter changes are much easier. I got the idea from my son's old S10 Chevy truck.
