I'm getting (have had) a noisy valve train on my 09 GT (85k miles) for a while now. I change the oil every 3,000 miles with mobil1 full synthetic and in general take good care of the car as a whole. Its a ticking more than a knock but I feel that it is just too loud to be totally normal? My driver's side catch can is also collecting a good amount of oil as well. Any ideas? It's driving me nuts. Also, both sides are making the noise.
