So I had my motor rebuilt. Cams installed. A few miles in I had the drivers side secondary cam sprocket fail. Luckily I had no piston damage or valve damage. A few days ago I met a guy who had the same failure here in Houston. Also Jdm cams. Drivers side secondary sprocket. Yesterday a man messaged me on Facebook curious about my outcome because he also had the drivers side secondary sprocket fail. And what the heck. Jdm cams. Kind of scary. Any one else ever heard of the sprocket failing? Is it common with cam changes or is it just crap luck
