Carl - Let me help you with a couple of things. First, I assume you do some kind of engine work for a living (or at least, as a sideline). If that is so, you should really learn that when a customer or fellow enthusiast tries to help others, but provides incorrect information, you gain absolutely nothing by being an asshole. Second, the information I posted was given to me by a noted (your would recognize his name instantly) race engine builder, so in addition to being so proud that you were able to correct John Lingenfelter (who was also apparently wrong about what happens when the plug is removed and not replaced), you could add this prestigious name to the list... that is, if like you, I was enough of a jerk to embarrass him publicly. And finally, if the plug being left out has absolutely no effect on the life of cam bearings, what do you suppose the engine builder to which I refer ACTUALLY did to eliminate the repeat bearing failure problem? He admitted that he discovered that the plug had been removed and not reinstalled, apologized for the error, and reassembled and dyno'ed the engine at no cost. And I never experienced a cam bearing failure again. So, if you can avoid telling me what an idiot I am, maybe you can help me understand what actually happened. Thanks.
