I am posting this on behalf of Cosmo, we had a phone conversation and he is away from his computer so I thought I would ask the great minds here to see if we can figure this out.
Cosmo is a daily driver. He takes many long trips during the year and on his recent drive from VA to upstate NY he noticed a slight ticking coming from one of the valves on cylinder #5. The noise only occurs after hours of driving then the ticking starts. Once it starts, he is able to pull over and isolate the noise to the #5 set.
Is he having a worn out spring? Any other areas to investigate?
