Hello captain, I am waiting for my recently purchased 260 to show up from Colorado. It is in transit as we speak. While my car was waiting for the shippers to show up I had the local datsun experts do a valve adjustment. When the valve cover came off, guess what? Yep, I have a 'going bad' oiler tube. Would you consider fabricating one more billet set up? Could you PM me when you can? Thank you, James
