Put on a new genuine Honda Drain Plug and washer
Not sure about needing a new drain plug. You could just clean it up. Did your threads feel all mangled up? If, after breaking the initial bolt preload, your drain bolt smoothly un-threaded all the way out, then you probably only needed a
new washer.
Recently I changed my oil and ATF. I noticed that my
oil plug alum washer was wrapped around the head of the bolt like yours was. Why don't mechanics replace this 25cent washer?
OdyFamily is right, these guys should face public slapping.
I believe the problem starts because the washer is not replaced. Then each time the drain bolt (either the oil or ATF) is reinstalled, it must be torqued higher to prevent leaks. Not good. Then we hear about some of these reservoir female threads stripping out. Nightmare scenario! Just change the 25cent washer!
