NOTE: Minimize chips in pan

Question:
A common question about repairing drain pans on the vehicle
is how do you keep chips from entering the drain pan?

Answer:
Using some general purpose grease on the drill and tap will help
prevent chips from going into the drain pan. Using a low RPM or
drilling by hand instead of using a drill motor would further reduce
the chips into the pan. Because we are only removing the old threads
with the drill, there will only be a minimal amount of material removed.

Optional tip to keep chips out of the pan would be pouring the old oil
back through pan to flush any remaining chips as it drains. Then after the
old oil has drained out, replace the drain plug and continue with the new oil.
Also remember the filter is there to catch any debris from normal engine wear.
