I bought some new tires and hit the old two lane highways to rack up some miles for the break in. Smiling from ear to ear. Guy in an older 3 series BMW got behind me and heard the sound. We pull into a quick shop and I shut it down talked for a few minutes got back on the road and realized I had a dead skip. Pull over again raised the hood and clackaty clack valve sound. Slowly limped back home to do a hot valve adjustment. Pulled the cover and found a lash pad off #3 intake valve spring.
