Hi guys, To respond to your question about the sealant, I don't know what is the right stuff. I have just used the same sealant as that with which I re-sealed the rocker cover gasket. Can't think of the name, but it has lasted a couple of weeks so far! I will keep an eye on it. If oil reappears in the tubes I will bother to find the right adhesive for the job. I know how to do it now! (I did read that a threadlocking compound is probably better, but didn't have any on hand) As for a mechanic who can do it right, I have no idea. I have yet to find a mech who I can trust. Which is why I am trying to learn how to do it myself. It's not rocket science. Kind regards, rubberowner
