Hi Chris,You may recall my last post where you advised to use Wurth RTV Silicone all purpose low volatile formula to stop the leak coming from one of my rocker shafts. Well it did the trick and we made it all the way to Charleston, S.C. and then Parade in Charlotte from our home in Canada and back, almost! Yours truly here ##?@@# obviously did not fully tighten the rocker shaft so in the last 500 miles I developed a leak again followed by a subsequent loud click which sounded much like very loose valves. One finger into the #2 lower plug (twin plug) cavity confirmed that the shaft had moved out part way. My heart was pounding as I removed the lower valve cover--thoughts of a bent valve tower box, oblonged shaft insert, etc. came to mind. Careful examination did not reveal any damage to the tower, rocker arm or shaft despite the fact that the shaft and rocker were at this point only supported on one side. I nevertheless replaced the shaft with spare including new o-rings, used some of the silicone and made sure that it was well tightened this time. 500 miles and no leak. All my fingers are crossed every morning before I check #2 plug cavity with my finger. For me the moral learned is check, tighten and check again particularly when it comes to the engine. Cheers
