One of my dad's friends did his own mechanic work, and he used Quaker State (non-detergent, yet!) because it used so much oil. When he took a valve cover off because he was going to do a valve job (265 CID V-8), the oil had congealed in the shape of the inside of the valve cover. The push rods and rocker arms were the only place that the Jello-like green sludge wasn't. Same in the lifter galley- the push rods were surrounded by green goo.
