I have to change the washer on the sump plug, to stop a little oil leak I have.
The oil in the car has done about 100 miles (if that), so not old at all. I do not think it is worth trying to take the plug out, stop the oil leaking with my finger and then putting the plug in again (with new washer). So I was going to drain it out, change the washer, put sump plug back in and then fill the oil back up.
With the oil being new and clear I was thinking of putting it back in.
Would anyone do this or just put new stuff in?
