Fresh engine, wiped cam? Tick? (new pics added)

Dont try running the engine. Buy an intake gasket and pull the intake and inspect it. The more it's run, the more likely the damage becomes severe if it's losing a lobe. A fresh engine will often have crap in the oil for the first couple oil changes. Especially if you havent changed the oil since the first start... (Which should have been done just after the cam break in procedure) If there is any chance of the lobe being gone, you must not allow the particles to keep runnning throught the oil system. Pull the intake and take a good long look (or post pics). I don't think adjusting the preload or lash and then running it is wise if you think there's a problem. It's like trying to sprint to see if the sprained ankle will affect you. All you're gonna do is hurt more.
