Lost Oil Pressure

[turbochargedv6]

Well here is the story I lost oil pressure while driving had about thirteen pounds of boost and let off and the car died. I tried to restart and heard a noise and the oil pressure was at about 5 pounds and shut it down. I thought I screwed up the bottom end but after dropping the pan there was no metal just a little silver swirl in the oil. The engine is rebuilt and gone through so I decided to take apart the top end and found a 19/32 softplug under the intake a little chewed up so I guess I found what the noise was, I am wondering does anyone know were I can purchase another one? I have gone to all the auto stores and nobody has them, It is one of the plugs behind the timing chain and is the reason why I have no oil pressure. I have searched online and can't find anything or anyone that has them any help would be great.
Thanks Frank
