Hello all, sorry for the delay, here is an update:
- Checked for vacuum leaks. I put a vacuum pump on the line from the pump, and it held 20" of vacuum for over 15 minutes.
- Pulled the tube to the air-horn...bone dry and clean as a whistle.
- The dirt in the intake side of the Turbo is probably from the K&N filter the PO had on the truck when I bought it. That went directly into the trash.
- No oil leaks.
