About 2 years ago I started having a issue of loud tappets when I started my 62 235. Not every time, some times it's quiet, some times it sounds like it's coming apart, like a echoing noise and quiets to tappet noise. Then the next time I start it it's quiet. The motor only has 1700 miles on the rebuild. I've changed two lifters that I thought were the problem. I'm tired of removing the floor boards. HELP!
