Hey guys just had a question about a valve job. I have an 04 wrx wagon and I just passed 30K. I am in a car club and do 6-10 track days a year. I am religious about oil (Mobil1 5W-30), tranny(Redline), diff(Redline), coolant, brake fluid(ATE Racing Blue), etc so the car is in good shape. I'm about to change the plugs because I had a guy in my car club recommend changing a little more often based on the driving we do. The engine sounds a little noisier lately and I think that maybe the valve train is getting a little loud. It's not anything extreme by any means but being completely anal retentive about my car I thought I would ask if any of you guys have experienced similar stuff with your cars. Have any of you had valve jobs? With the kind of driving I do does it seem likely I need one?
