Hello, I am hearing a distinct tapping noise in the left side of the motor. This is only after the engine reaches operating temperature. It is not there at all when the engine is cold. I have 170-175 compression on all cylinders, and all the carbs are synced equally. Valves are all adjusted correctly. The engine runs perfectly at 70,000 miles. Last week I changed both timing belts and 2 scored lifters on the right side of the motor, but didn't do anything on the left noisy side. The noisy side lifters look fine. I am not sure if the noise is related or not. I was extremely careful when changing the timing belts. I used napa timing belts.
Any Ideas?
