Even valves out of adjustment can cause rocking. I adjusted the 84SD this weekend and was amazed at the change. A couple were tight. The engine starts quicker and idles better.

Strange because the valves were adjusted not too ong ago. Other cars I've owned with solid lifters became loose, not tight. I wonder what's up.
