Have just done my first oil change, I bought the car in october 07, should have done it a bit earlier i know!
Got the plug out ok (previous owner had to helicoil it when he changed the oil before he sold it), but the plug is covered in filings! Is this something to be worried about? - also the washer isnt copper (i dont think)

and the long thin bit im pretty sure is just PTFE Tape.
any help would be great, cheers
