<div style="color:black;font: 10pt arial;">My 1976 TR6 has a little ticking sound at idle, as if a valve is sticking a bit. I am curious if I can assume that this is normal rattle on these engines as things wear or if I should start paying closer attention. To my knowledge the valve seats have never been hardened. I recently set the valve lash and believe it is spot on. Engine has about 54,000 miles. Also, does anyone use an oil additive on a regular basis and what has been your experience or recommendations. Thanks for any ideas or suggestions.
