Yes we ALL know that I should hang up my wrenches and never touch a car again. Stated multiple times by numerous ppl. Thanks for adding to the number.
I checked the cam before installing it. I didn't put a gauge or dial on it but none of the lobes looked rounded off. To have a misfire in a cylinder, I would think the cam would have to be pretty rounded off, not just slightly wore. My dart sport had a rounded out camshaft completely. It sounded like a rod knock. I assumed that's what it was so I pulled the motor to find out it was the rear camshaft lobe. It was rounded off completely.
What I'm saying is there's no knocking or banging or clanking. Plus, like I said, I wouldn't have put a camshaft in that looked bad or even lightly wore down. They're cheap enough that I would replace it at that point
