This valve stem image shows the occlusions in the coating that occurred on a specific batch of valve stems, which caused excessive wear of the valve guides and resulted in premature failure.

Add CommentJoe Gibbs needs to use his new Nikon microscope and take a better look at his drivers. He, just might find all his problems!!
Reply | Report Abuse | Link to thisI know that these articles are supposed to be general interest 'quick reads' but this one was very disappointing to me. Let me see if I have this straight: JGR was having problems with some engines, they got a new microscope, they looked at rocker arms and then everything was fixed. The only thing that I really learned was that these folks were way behind the times because they couldn't share images with their suppliers and now they can. Where is there any science in this?
Reply | Report Abuse | Link to thisI read it again. It is really just a Nikon advert. Nevermind.
Reply | Report Abuse | Link to thisI am well aware that Scientific American standards have declined greatly since the magazine's heyday half a century ago - but this article takes the cake ! Please, dear editors, take us back to the future and once again begin to publish basic science articles written by persons engaged in the respective field of endeavour....

"We're getting 875 horsepower out of 358-cubic-inch motors. If you know anything about motors, that's not supposed to happen."
Reply | Report Abuse | Link to thisIf you know anything about motors, you'd know that F1 cars produce 750 hp with 2.4L engines. That's twice more power per cubic inch than your car. And top fuel dragsters produce 7,000 hp with 8.0L engines. That's over five times more power per cubic inch. What's not supposed to happen is the cracks in your engine. That's poor engineering. The engine is supposed to break after the race.
