So I have three engines I want to turn over to test the compression. I think the philosophy is turn it over and document the output. If pressure is low in some cylinders, squirt some oil in them and retry. If it improves-bad rings, if not-sticky/obstructed/burned valves.
first, these things have been sitting for years, I’m leery of not lubricating the cylinders before turning it over. But I don’t want to get false readings on the rings. Maybe oil, rotate the engines, then let them sit a week or three?
second, how much oil is a squirt? I know it’s silly, like a pinch of salt, but like a tablespoon?
