Metal in oil

[putnam00]

I have changed my oil twice once in sept the oil plug was covered in super fine shavings, I know some is normal. When I changed it last weekend the oil plug again was covered in shavings and you could even see it in the oil. I know something is bad, could it be the oil pump? I have run about 20 psi when its cold and it will go past 40 it high rpms, but around valentines day i actually had the display say low oil pressure and ran really low, I stopped checked the oil and it was only 1/4 of a quart low. i restarted it and it was showing more pressure. it has just over 235,000 miles and runs good i have a picture of the oil shown
