so i thought i got rid of my timing chain tensioner problem after i purchased a new one, but i was wrong. this one went bad after about a year (9k miles). i read the DIY on sandblasting the worm gear to eliminate the rattling, and figured i should give that a whirl. anyone know of a place where i can get a small part sandblasted?

 

I bought a cheapo sandblaster ($15) at harbor freight. Also bought media ($20 or so for 20lbs.)

 

i used old fashioned sandpaper and it worked just fine for me
