I got a set of nice cam towers from a friend who had them in storage for a long time. I debated whether or not to remove the spray bars. Glad I did. Look what I found in one of them- a big hunk of......... dirt/mud? I heard something rattling around in the tower and couldn't shake it out. So I removed the M12 fittings and that's when I found the chunk of dirt in there.

Yup, that's why all my parts were shipped to Ollie's. There's some things with a 911 engine any machinist should be able to do, but I feel safer sending it to someone that specializes in our cars.
