well guys I was able to get the harmonic balancer correct[place front washer on wrong] after timing belt change. notice valve chatter is getting kinda loud after 355k/miles what would be the opinion of my fellow brick rider.adjust and replace shims or contiue to drive & turn radio louder. I have read some threads saying don't worry about and others say it's maybe cam wear after many miles and won't help the performance.what's the group opinion????
