[QUOTE="Doubt 1T, post: 16446381, member: 197329"] *Update* So I had the car on the lift and really tried to source this out. It sounds like its coming from #8 Cylinder like the TSB said :( I let the car sit on my lift for 40 mins with pretty much zero noise, I was just lightly blipping the motor to hear for any noise and nothing. Once I was really revving the motor up the noise came out of no where like a light switch as if the higher RPM triggered it but it would go away when I would rev the motor around 1500 RPMS if that makes sense to you guys. Being I was by myself I couldn't rev it and be under the car at the same time so I put the AC on full blast to put more of a load on the motor and the noise came back consistently "click click" pause click click click pause etc. I used my stethoscope on the valve cover bolt of cylinder #8 and I can hear the noise. I believe it sounds like more of tin sound vs the rest of the cylinders but very hard to tell it almost sounds identical to the others, you can also hear it clearer if you put the stethoscope on the Driver side Exhaust / CAT and of course you can hear it from Driver side wheel well like the TSB states. I've noticed the hotter the car runs the more the noise happens. What puzzles me is how all the sudden I got the noise after 23k id be more understanding if it happened a lot earlier on these cars but who knows I gues this can come at any time?? Anyway here's a video underneath the car, sorry if I was moving around a good bunch it was hot as hell under there haha [MEDIA=youtube]cuVV6KFcSt4[/MEDIA] Jonah- [/QUOTE]
