Okay, I have posted this before, but wanted to start a new thread since I now have more details. Here is the issue, when I drive around town and travel no faster than 50mph, everything seems OK. When I travel on the highway and do more than that, or above 55, I hear sporadic banging under the valve cover. When I remove the valve cover cap, the inside appears dry. I think the banging is from unlubricated valves. I add Marvin mystery oil and let it sit, then the banging goes away and it seems okay. it is only when I drive at high speeds. I know, I can just drive around town, and that really isn't a problem, but I would like to have this issue resolved.
