I built a K24 with an A2 head. I installed Skunk 2 stage 2 tuner cams, Skunk 2 valve springs, Skunk 2 Titanium retainers, Skunk 2 tensioner. All these Skunk parts were brand new. The timing chain was a brand new K24a2 chain. I put 900 miles on the engine and now I'm having bad chain slap and rattle. I will note that the TCT rattle occurred from day one. Yes, I read all the stories about the Skunk 2 cams having issues back around 2006 and they were supposed to fix it with version 3 cams. It's 2020 and these cams are still not working correctly and it's frustrating. I called customer support and they said they have never heard of any issues with their cams. I hate being lied to because I can literally pull up dozens of threads. I will post a video up of the problem, and the noise it is making. I'm going to remove the TCT and check the chain to see if it stretched, but something fishy is going on with these cams because they should not have been making noise, and they have since day one and it is only getting worse. Why I didn't just buy another cam.... now I'm kicking myself.
