There's some clown on a Yahoo video who has glued pens to his 300SD. I'm a
computer dolt so I don't know how to put a link in a post.
If you frequent Yahoo, give it a gander...I don't think this guy is hooked up
right.

Turbo was from the '82 300D with 74kmi in unknown condition. Both the original
turbo and the current one have no axial play but do have slight side to side.
Tell me more about the foot valve. Is there one on the turbo oil return line
also?
